There’s a lot of talk of a “new” ingredient in the cosmetics industry and its benefits. But in fact, there is nothing new about cannabis.

Information and statistics on its use and benefits are widely available. In our opinion, the most important thing to keep in mind is that people have been using this plant in different ways for more than 8,000 years.

Cannabis is used to make hemp, which has multiple uses and benefits. For example, from the 16th to the 19th century, it was an essential material in the textile industry, competing directly with cotton. A curious fact in this regard is that King Henry VIII of England required all farmers to allocate part of their land for the growing of hemp in order to produce sails for the navy.”

However, in the 20th century, the word "hemp" began to gain a bad reputation and was directly linked to the psychotropic substance THC, as reflected in the Single Convention on Narcotic Drugs of March 30, 1961 in New York.

Beyond the issue of why this natural substance was “banished” from society, while the consumption of other harmful substances has been encouraged, we would like to explain how this ingredient has evolved and become one of the most sought-after compounds in cosmetics today.

As trivial as it may sound, it all comes down to legal loopholes that arise when certain restrictions are imposed. As such, both hemp leaves and seeds are excluded from the list of narcotic drugs, so hemp seed oil (Cannabis Sativa Seed Oil) can be used in cosmetics as long as the THC content does not exceed 2% (according to European legislation).

Now, we would like to tell you what CBD is and why it’s becoming increasingly popular.

The first thing you should know is that the human body has an endocannabinoid system. Discovered in the 1990s, it produces two types of receptors present in cannabidiol, more commonly known as CBD. This system is very important, as it regulates the majority of the physiological processes in your body on a daily basis. In other words, it keeps your body balanced despite external variables.

 So what happens if your endocannabinoid system doesn’t work correctly?

You get sick.

Returning to the subject of receptors, it’s important to identify where these two types of receptors are located:

CB1 receptors (linked to THC): they are mainly concentrated in your brain.

CB2 receptors (linked to CBD): they are concentrated in both your immune system and nervous system. But they are also present in your liver, heart, kidneys, blood vessels, and endocrine glands.

 

Keeping in mind that CBD has no psychotomimetic effects on your body, let’s look at how it benefits your skin.

As we indicated above, the oil approved for use in cosmetics must come from hemp leaves or seeds. These seeds are rich in omegas 3 and 6, which are well-known for their regenerating and moisturizing properties and highly beneficial to the skin.


 
 

However, the benefits of CBD go much further, because your skin also has cannabinoid receptors that help to maintain and protect it. For example, the endocannabinoid system is involved in various skin conditions, such as dryness and acne. It plays an essential role in controlling the skin’s condition, as it helps to regulate the growth and differentiation of skin cells.

Some studies also point to CBD as an adaptogenic agent, helping the skin to adapt to different environmental states and thus preventing it from being damaged; this makes it quite beneficial to sensitive skin.

Another reason why CBD is increasingly present in cosmetics is that it has anti-inflammatory, analgesic, and antioxidant properties.

In fact, CBD has a long list of benefits, but in our case, we only want to explain those closely related to the skin. We hope that we have helped you to understand why this ingredient is interesting and holds potential. However, don’t be fooled by long lists of benefits. Remember, there are no magical solutions, and the fact that your mascara contains CBD probably won’t benefit your body in any way.

It was the year 2014 and the first articles on the subject appeared in some magazines and fashion blogs in European. It was information without content, because there is no point in talking when do you don’t know what you’re talking about, like many things you can find on Google. At Per Purr, we like to understand what we are talking about and, most of all, try things ourselves before recommending them, because it is very easy to get lost in the game of telephone that is the internet.
 
I started researching scientific articles that could explain the physiology behind the interaction between infrared rays and our beloved skin. The first articles I read were practically copy & pasted. I found experts contradicting themselves within the same article. Other research said things like: infrared spectroscopy and magnetic measurements, {Gd38 (ClO4) 6}, encapsulating six ClO4? ions?
 
Is this information, which is almost impossible to decipher actually useful to us? What I do know how to do is use something, test it on my skin and evaluate it.
 
I asked my husband, who is a doctor (and partner of Per Purr), what he thought about infrared rays. He, somewhat incredulous, went to research this hot topic. He asked two pathological anatomists (people who are cooped up in the laboratory behind the microscope looking at cells) at his hospital about this great “discovery” and he told me that they both laughed at him, telling him that it wasn’t like that.
 
Here's what he explained to me:
 
“Infrared rays are thermal energy, that light and pleasant heat that we feel when the sun touches our skin. They are not only emitted by the sun, but also by dryers, laptops, heaters, hot sidewalks and many other things. Humans also emit these rays, which are captured by night vision cameras.”
 
 

 
 
The sun’s ray is subdivided into 3 parts: UV rays - 7%, IRA rays - 54% and visible rays - 39%, which may be the next target of skin science. But what interests us here is whether these rays have the capacity to damage our skin.
 
Visible rays are what allow us to see the rainbow and are stronger than infrared rays. Why did a ray that is weaker than the rainbow become the new villain? Maybe because it is not as beautiful? Who would have the courage to accuse the beautiful rainbow of causing skin cancer?
 
So how can infrared rays cause damage? The answer is very simple: free radicals.
 
Almost all sunscreens available on the market today block half of the free radicals formed in the skin, as these free radicals cause premature aging and skin disease.
 
What is a free radical, anyway? It's a highly reactive short-lived molecule derived from oxygen. Oxygen is present everywhere and, as its name suggests, it oxidizes like rust on metal, what we call "oxidative stress.”
 
Okay, but if IRA rays produce these free radicals in the skin, wouldn’t dryers, fires and the heat of human contact also cause cancer?
 
 

 
 
No! After all, there are other factors in this equation, such as intensity and length of exposure, which leads us to understand that just by sitting very close to a heater we can feel the burn. There are two important issues to clarify about this infrared issue:
 

  1. Free radicals are not only produced by infrared rays, but also and mainly by ultraviolet rays. And you know what else? When the body’s defense cells destroy "invaders", they generate the same free radicals as infrared rays.

 
It seems that the villain has been unmasked and is not as ugly as we thought.
 
Excessively produced free radicals cause damage and must be combated. By whom? By antioxidants. A good sunscreen should have good antioxidants that act on ultraviolet rays. This is the key point: free radicals are not a new discovery and, in the fight for protection against UV and IRA rays, the antidote is exactly the same.
 

  1. Research on effects of the sun on the skin shows that IRA rays penetrate deeper than UV rays. However, it is very difficult for a sunscreen to go beyond the horny layer of the skin (the first layer of the epidermis, which is subdivided into many layers of dead cells), because the function of this layer is precisely that of protection; a skin protector that does not allow any chemical agent to penetrate.

 
Even using the latest nanoparticle technology in sunscreens, pathological biopsies (the study of microscopic tissue structures) show that the horny layer of the skin allows less than 1% of all topical agents we apply to the skin to penetrate.
 
IRA protectors are sold as a protective barrier. But is an antioxidant a barrier? In theory, maybe. UV protectors are chemical and physical filters, true walls, inorganic particles (like titanium dioxide) that absorb and/or reflect the rays, which is not the same as an antioxidant.
 
Last but not least, we have a chemical factor that reveals the whole picture: vitamin C is still the top antioxidant and must be present with at least 10% of the formula in a very acidic environment (pH 2.5 - 3.5) for its effect to be stable and efficient.
 
This new topical application (UVA + UVB + IRA protectors) that is invading the market has created high expectations but with low amounts of antioxidants. Today, it is still NOT possible to find a sunscreen containing 10% to 20% vitamin C because UV filters already make up 20% of the formula, and these require a basic pH (6-7), which would destroy the vitamin C.
 

 
 
What can be done to further protect the skin?
 
It’s very simple: instead of trying to find just one ideal product, it is better to use two real products. For example, use a serum with a minimum of 10% vitamin C and then an SPF 50 sunscreen.
 
With all this complex information, there is no need to frown upon infrared protectors, because even though they are not as effective as they claim to be, they are still a little more complete than normal ones that only contain ultraviolet protectors. The difference is especially noticeable when there is overexposure to the sun (such as during a beach holiday or a poolside weekend).
 
 

Melatonin is a hormone that regulates the sleep-wake cycle by causing drowsiness and lowering body temperature through sensitivity to ambient lighting. It works best at night with the natural circadian rhythm. While sleep is incredibly important, melatonin also operates directly with the central nervous system, which ultimately really puts us to sleep.

In the 1990s, it was discovered that melatonin had other functions in our bodies, such as the elimination of free radicals, which makes it an endogenous antioxidant. Need more?

It is not just an antioxidant, it is a super antioxidant.

It can cross cell membranes and also the blood-brain barrier, a filter that regulates fluid and materials that enter the central nervous system. Upon entering, and unlike other antioxidants such as vitamin C, vitamin E, and glutathione, it does not undergo the “redox cycle”. The redox (reduction-oxidation) cycle occurs when an electron-poor antioxidant, such as those mentioned above, donates its electrons to cancel the effects of free radicals (highly reactive molecules that cause damage precisely because they do not have paired electrons, and molecules that need electrons to stabilize). Because they don't have a lot of electrons to donate, they can become “pro-oxidants”.

 

melatonin post perpurr

 

Melatonin is an electron-rich molecule and can interact with free radicals through an additive reaction, forming various stable-end products excreted in the urine. From this point of view, melatonin can be considered a terminal antioxidant. Many already know that its production is directly related to sleep cycles. But what few know is how good it can be for the skin.

From the age of 30, the synthesis of melatonin begins to decrease, which explains the insomnia crises of adulthood. Melatonin deficiency is also related to depression and obesity. But what does it have to do with beautiful skin? As we said before, melatonin decreases cell oxidation endogenously, being one of the most powerful antioxidants ever found in nature.

Antioxidants in turn decrease the premature aging of cells and, consequently, the skin; smoothing and preventing wrinkles and eliminating the "tired" appearance that we dislike so much. It also helps control changes in skin pigmentation by adding melanin to melanocytes, causing the skin to change color. This interaction is also responsible for the paler color of the skin of the elderly and people suffering from insomnia.

In addition to skin pigmentation, it is also related to melanoma control, because melatonin receptors are expressed in various skin cells, including keratinocytes (keratin-producing cells, predominant in the epidermis) and fibroblasts (cells related to healing and other functions). Melatonin can also suppress ultraviolet (UV) light that causes damage to skin cells, exhibiting strong antioxidant activity in cells exposed to UV rays. Therefore, melatonin synthesized locally or topically applied* could neutralize environmental stress.

Our skin acts as a barrier between the environment and the grand organism (our body), since it is constantly subject to the actions of solar, thermal, mechanical energy, chemical and biological agents. Evolution has allowed it to develop unique properties to deal with these stressors, making it endowed with abilities to recognize, discriminate, and integrate specific signals within a highly offensive environment and integrate them into a neuroendocrine and stress response system. Further,  the skin has the ability to generate new vessels, cellular tissues, and rehabilitate scars and wounding.

Melatonin is not yet used in sunscreen creams, probably due to incompatibilities with the substances used to protect against UV rays, which require a very high pH to be stable. But the use of its properties for topical purposes is already being used in humans: melatonin in a pliable cream formulation can form a deposit in the first layer of the skin from which is continuously released into the blood vessels. Thus,the skin becomes a target organ, not only for the treatment of local routes, such as topical application, but also allowing a transdermal supply (that passes through the skin) reaching our circulatory system, creating internal treatment through this constant within the skin.

We leave you a list of foods that help in the production of this hormone: oats, berries, corn, red wine, tomatoes and oranges, potatoes, nuts and rice.

Easy, right? Nothing outside of our usual diet.

In addition to the food, to have a better production of melatonin, we must monitor environmental factors: seasons, temperature, ambient lighting, and endogenous factors such as stress and age. The story that you shouldn't sleep with the lights on, or with the TV on, can be considered correct. If there is a minimal light source in the room or if the temperature is not pleasant, you can have an uncomfortable night or a series of them. It must have happened to you, right?

Melatonin in supplement form is easily found in drugstores.

Some Pointers:

  1. If you live in the far northern hemisphere with endless days in the summer and it takes you forever to fall asleep, try to close the blinds "early", since it takes about 4 hours for the body to assimilate the darkness and start producing melatonin.
  1. Eat the aforementioned foods within a varied diet.
  1. If you travel a lot and have problems with jet lag, or have a crazy routine, or just want to sleep better every day, we recommend taking melatonin as a supplement (restful sleep and beautiful skin!). 
  1. *There are also options with melatonin for topical use in all pharmacies such as serums, ampoules and creams.

 

So, sleep tight! We are working for taking care of you!

El ácido retinoico es una forma de provitamina A y sus efectos varían con la concentración utilizada y el tipo de tratamiento utilizado. Normalmente los tratamientos a base de estos ácidos deben ser realizados en esta época del año, cuando la radiación solar es bastante menor.
Los dermatólogos y cosmetólogos suelen utilizar concentraciones más altas, para exfoliar la piel más profundamente favoreciendo la renovación celular más rápida. En las cremas de noche suelen aparecer en concentraciones más bajas y con efectos más sutiles, ofreciendo resultados visibles a medio y largo plazo.

Estos tratamientos son eficientes pues hacen una exfoliación química, que estimula la formación de colágeno. El tratamiento en casa, implica el uso de un cosmético que contenga ácido retinóico al menos dos veces por semana, dependiendo de la condición de la piel.
Las personas con pieles sensibles no deben usar continuamente este activo y es importante que antes de comenzar el tratamiento se haga una prueba en una pequeña zona de piel para comprobar que no surge ninguna reacción no deseada como picor, enrojecimiento e irritación severa.
Aunque se sabe que el uso de betacaroneto protege la piel contra la agresión solar, el uso de productos que contienen ácido retinoico debe ser siempre por la noche, ya que es foto-sensible.
Durante el tratamiento lo mejor es evitar el sol y utilizar un filtro con SPF 50. Si la piel no está bien protegida el problema puede agravarse e incluso causar nuevas manchas. Entre una y cuatro semanas la piel se mostrará más brillante y uniforme.
La comida también puede ser un buen aliado para iluminar la piel. Algunos alimentos tienen un alto contenido en retinol, tales como las verduras de hojas verde oscuro y las frutas de color amarillo-anaranjado, que deben consumirse siempre.
 

Clays have a wide range of properties and colors that vary according to their mineral composition. What they all have in common is their high capacity for absorbing toxins and waste found on the skin that aren’t removed during daily cleaning.
Using clay for a deep cleaning once or twice a week will give you cleaner and healthier skin.
One good idea is to add plant and essential oils, honey, fresh fruit or yogurt to the clay. Or if you are more traditional, you can add a little mineral water. These additions benefit your skin in ways you can’t imagine.
Clay masks leave your skin clean, velvety smooth and improve blood circulation in the area under the mask. Moreover, this “magic dirt” is one of the most powerful natural antiseptics and anti-inflammatories that exist.
Here are some suggestions we have already tried at Per Purr. Yes, we are working, but we are also taking care of ourselves at the same time.

Clays, The best medicine for your skin!

Clays, The best medicine for your skin!

Green clay

Green clay is the most well known clay, and it is used mainly on oily skin susceptible to acne. It can completely extract the oil from your skin and kill the bacteria responsible for causing pimples. This mask can be used two to three times a week.
Recipe:

  • 2 heaping tablespoons of green clay
  • Warm or cold water. Use as much as needed to achieve a uniform cream
  • 1 teaspoon of honey
  • 5 drops of propolis extract

 
Instructions:
Mix all the ingredients well and apply to clean skin. Apply and leave on for 20 minutes. When the mask begins to dry, rinse off with warm water and apply your usual creams.
 

White and yellow clays

White and yellow clays are good for normal and sensitive skin. This clay cleans your pores without removing oil from the skin, maintaining the skin’s natural hydration, which is very important for sensitive skin. It also soothes skin irritations caused by changes in the weather, skin treatments or excessive sun.
Recipe:

  • 2 heaping tablespoons of white or yellow clay (or both)
  • Warm water. Use as much as needed to achieve a uniform cream. In this case, you can also use an herbal distillate (plant water), such as chamomile, lavender or rose, instead of water.
  • 1 tablespoon of natural yogurt (NOT fat-free!)

Instructions:
Mix all the ingredients to create a uniform cream and leave the mask on your skin for 20 minutes. Rinse with warm water. The effects of the mask are better and more visible if you apply at night before bed. When you sleep, your skin rests, and the next day, it’s radiant.
 

Pink (or red) clay

This is without a doubt the clay most recommended for dry, mature and blotchy skin. It has clarifying properties and can be used frequently.
Recipe:

  • Two heaping tablespoons of pink clay
  • Enough warm water to achieve a uniform cream. (Rose water is perfect for this)
  • 5 drops of jojoba oil
  • 1 teaspoon of honey
  • 3 drops of rose essential oil (Careful! It must be pure)

Instructions:
After mixing the ingredients well, leave the mask on your skin for 20 minutes, then rinse with water. The next day, you will notice your wrinkles have diminished.
 

Ghassoul (pronounced “Rassoul”)

This is a Moroccan clay rich in silica, a mineral that is vital to regeneration of the deepest skin layers. It improves elasticity by stimulating collagen production. It can be used for all skin types. This clay is a bit different than the others because it absorbs more water after a few minutes have passed, resulting in a creamy texture.
Recipe:

  • 1 heaping tablespoon of Ghassoul
  • Enough water to create a creamy mixture. Ideally, add a little water, wait 10 minutes and add more. If you need more and think it is still not creamy enough, wait 10 additional minutes and add more water.

The supplements for this mask vary according to skin type. Honey always produces good results with all types.
In the world of clay masks, talking about limits is like putting walls on the sky. Clays are easy to find, affordable and normally found at any health food store. Now you have no excuse not to flaunt your clean and beautiful skin.
 

Speaking of healthy skin, we know there are many steps: diet, protection, hydration, etc., but what many people forget, or simply skip, is good daily cleaning. Daily cleaning will undoubtedly change your relationship with your skin.
This seems just as obvious to us as a good selection of products. Each person’s skin is unique and needs distinct care; later, we will have to make you a one-hundred page list to cover all the skin types. Instead, our idea goes beyond products. We would like to stress routine and the proper way to clean your skin.
First, for those of you who have never seen a dermatologist, look for one. People often believe that they have one type of skin and spend all their lives using products that aren’t really appropriate. Additionally, only a dermatologist can diagnose any other problem you didn’t even know you had.
It isn’t effective to spend money on the best creams on the market if you don’t have a daily cleaning routine twice a day: when you wake up and when you go to bed. At night, the basic rule is to always remove your makeup. ALWAYS!
d61921e32e55de8e480ab82b3c54f160
Ideally, first take off excess makeup with a non-aggressive product, like micellar water (there are several brands in all pharmacies). Then, if you wear eye makeup, you may need an oil-based product to effectively remove mascara, which is important for not clogging eyelash pores.
From here, you could move directly to the toner, but we recommend you to rinse your face with warm water for one or two minutes, or use some product: a neutral soap or cleansing foam. Now you have a fresh, mission-completed feeling before moving on to toner. Then you must put on a night cream and eye cream and…voilà. Off to bed.
I don’t believe in excuses for not going to bed with clean skin: not the rugged routine or your partner telling you that you’re taking too long to come to bed. Please. This process takes barely 15 minutes.
There are "three-in-one" options to remove makeup, clean the dirt accumulated during the day, and tone. It’s a question of how to invest your time.
Maybe we should have started the other way around. Night cleaning is certainly the most well-known. Many people think that in the morning the skin is clean because they’ve just spent all night in bed. Don’t be fooled!
At night, your sebaceous glands continue working by secreting everything left in the pores and other toxins. If you want your skin to absorb products like vitamin C serum and sunscreen, you must clean it. You can even just rinse with warm water and lightly massage the skin or use a cleaner specific to your skin type, but you cannot skip this step.
As far as products go, in addition to knowing which one is best for your skin type, you should also keep in mind that throughout the year, skin is affected by the change in seasons, and this should be reflected by changing your products. In the winter, with the dry air, strong wind, household heating, etc. you should choose gentler products.
If you do not have these basic care habits for cleaning your skin, we suggest you start now and try it for a few weeks. You’ll see a 180º change in your relationship with your skin and how your skin shines. Now tell us all about it!
