The importance of knowing about Comedogenic Rating of Carrier Oils and Butters
Knowing about the comedogenic rating of carrier oils and butters is a very important point to consider when preparing our own natural products at home.
In this way, we make sure to choose the perfect and appropriate formula for our skin type, in order to achieve the wanted result after the applications.
Unfortunately, although there is a wide range of natural oils to choose from, there is a lot of misinformation about this topic. For example, that coconut oil or sweet almond oil are good to use as a make-up remover or moisturizer, when the reality is that if we use them without a proper information, they can cause many unwanted effects on our skin.
However, the use of coconut oil with other vegetable oils or blended with creams, may reduces the occluding action of coconut oil by itself.
Each natural vegetable oil has its own characteristics which allow them to provide certain benefits. Likewise, they also have components that classify them according to their tendency to clog pores in the skin, what is known as Comedogenic Rating.
What makes natural oils so beneficial for our skin?
Natural oils for skin care are increasingly preferred by society today, which when choosing, is opting for organic and animal cruelty-free products, just to name a few.
Instead of soaking our face and body with chemicals of dubious origin, we are discovering the incredible power of the benefits of natural oils for skin care, whether for therapeutic or aesthetic purposes.
In addition, each oil can be combined with other natural extracts such as essential oils to create highly effectives homemade serums and masks, since they have been proven to fight acne, wrinkles, scars, infections, eczema, rosacea, hyperpigmentation, and many other skin conditions.
Carrier oils as vegetable, nut, or seed oils are used to dilute essential oils and carry them onto the skin and into the body. The same happens with vegetable butters, which are more suitable for body application.
Butters and vegetable oils are a good source of oil-soluble vitamins, such as A, D, and E, as well as essential fatty acids, all of which are needed by the skin to maintain its health, tone, and elasticity.
What is a Comedogenic Rating?
A comedogenic rating gives us an idea of how likely it is that an ingredient or oil will clog pores. In this way, people who are prone to breakouts should avoid comedogenic oils as they will exacerbate pimple formation.
On the other hand, people with drier skin might prefer a more emollient oil toward the middle of the scale.
The scale uses a numbering system of 0 to 5, where Ingredients are rated as following:
- 0 Will does not clog pores
- 1 Low likelihood of clogging pores
- 2 Moderately low
- 3 Moderate
- 4 Fairly high
- 5 High likelihood of clogging pores
In addition to the comedogenic rating, the application of high quality, unrefined organic vegetable oils offer an array of valuable nutrients to support, nourish, and enhance the functions of the skin. These nutrients include:
- Fat-soluble vitamins and nutrients
- Essential Fatty Acids (EFAs)
These nutrients, (especially essential fatty acids such as linoleic and oleic acid) will help us identify the comedogenic level of an oil.
Fat – soluble Vitamins and Nutrients in Vegetable Oils
Vitamin E
It is one of the most important antioxidants, which means that it is able to prevent cell damage from the destructive elements of free radicals.
Free radicals, when in excess, can damage healthy tissue, destroy the collagen and elastin fibers that support the skin and interfere with the formation of fresh healthy skin cells making our complexions blotchy and dull.
Vitamin E helps to protect the skin against environmental pollutants. It is used topically to reduce scar formation and to treat burns, including radiation burns.
Besides, vitamin E assists wound healing and has great repairing and regenerating properties. In conjunction with beta-carotene, vitamin E may decrease the harmful effects of the sun.
Vitamin A
It is an essential vitamin for cellular growth and repair of body tissues. Vitamin A plays a crucial role in preserving the integrity of red blood cell membranes as well as the skin.
Some symptoms of deficiency of Vitamin A include: rough, dry and scaly skin.
Beta-carotene
B-carotene is one of over five hundred carotenes that occur in nature. Beta-carotene, a precursor to vitamin A, is considered to be one of the most active of the carotenes.
Oils rich in Beta-carotene tend to be a rich orange color.
Beta-carotene is found in: carrot herbal oil, palm oil and algae. Palm oil also contains the carotene lycopene, which appears to have more anticancer abilities then beta-carotene.
Additionally, it may play a role in protecting the skin from the damaging effects of the sun, beta-carotene functions as a cellular screen against sunlight-induced free radical change.
Vitamin D
This works with calcium to build bones, teeth and healthy skin. It promotes healing and is good for burns and abrasions. Avocado oil is the only vegetable oil that contains vitamin D.
Lecithin
This is an important component of cellular membranes, particularly those of the brain and nerves. It is a powerful emulsifying agent and helps to remove fats and cholesterol from the blood.
Essential Fatty Acids (EFAs) found in vegetable oils
Essential Fatty Acids are called ‘Essential’ because our bodies cannot produce them, therefore we must consume them in our diets and apply them to our skin.
EFAs are an important part of the membranes of every cell in our body. Without a healthy membrane, cells lose their ability to hold water, vital nutrients, and electrolytes. They also lose their ability to communicate with other cells and be controlled by regulating hormones.
There are many fatty acids usually found in vegetable oils. The two that are most common are Linoleic acid and Oleic acid.
Unrefined polyunsaturated oils such as flax seed, evening primrose, borage, passionflower and rosehip oil, are rich in EFAs.
Fatty oils rich in EFAs are extremely reactive and are easily damaged by light, heat and oxygen exposure. Keep oils rich in EFAs refrigerated.
Linoleic Acid
It is an essential fatty acid that is important to building the membranes which surround every skin cell. It helps to strengthen the protective lipid barrier that lies beneath the surface of the skin and guards against moisture loss.
Lack of linoleic acid can lead to serious skin problems, premature aging and can reduce the strength of the skin’s supporting collagen fibers which may slow wound healing and can trigger hair loss.
Oils high in linoleic acid are lighter and thinner in consistency. They nourish and protect the skin without being too heavy.
Linoleic acid can restore the skins barrier function and reduce scaling. Besides, people with acne have been shown to have low levels of this acid in their skin.
Non-comedogenic oils tend to be the ones that have high-linoleic acid contents, since it is lighter and absorbs into the skin, without clogging pores.
It has anti-aging, barrier protective, soothing, and balancing properties, and is most suitable for oily and acne prone skin.
The highest linoleic acid ratio is found in black cumin, evening primrose, hemp, grapeseed, guava seed, passionfruit, papaya seed, prickly pear, pumpkin seed, red raspberry, rosehip, safflower, sunflower, soybean and wheat germ oil.
Borage, castor, cherry kernel, chia, kiwi seed, pomegranate and sesame oils contain high linoleic acid, but have more balanced profiles.
Oleic acid
It is a monounsaturated fatty acid. Vegetable oils with a high content of Oleic acid are more resistant to the damaging affects of heat and light.
Generally, oils higher in oleic acid are better for dry skin types; they are heavier and richer than oils high in linoleic acid.
The acid is absorbed well by the skin, has anti-inflammatory and skin softening properties.
Oleic acid is more occlusive and seals in moisture, creating a film on the skin. Oils high in oleic acid can clog the pores of those susceptible to acne.
The highest oleic acid ratio is found in sweet almond, apricot kernel, avocado, carrot seed, hazelnut, macadamia, macula, olive, palm, sea buckthorn and canola oil, as well as cocoa, mango and shea butter.
Argan, abyssinian, jojoba, rice bran and tamanu oils contain high oleic acid, but have more balanced profiles.
Gamma Linoleic Acid (GLA)
Oils rich in gamma linoleic acid can play an important role in treating inflammatory conditions including eczema, psoriasis, and rheumatoid arthritis.
Apart from breast milk, evening primrose oil, black currant, and borage seed oil are the main sources.
Lauric Acid
It has antibacterial and anti-acne properties. Found in babassu, coconut, date seed, and palm oil.
Myristic Acid
Found in babassu, palm, and coconut oil. Myristic acid has cleansing and lubricating properties.
Palmitic Acid
It possesses soothing, hydrating, anti-aging and barrier-protective effects. High in baobab, brazil nut, macadamia, palm, peanut, rice bran, sea buckthorn and neem oils, as well as mowrah butter.
Palmitoleic Acid
An omega-7 fatty acid with anti-aging, healing, and rejuvenating properties. It is found in macadamia and sea buckthorn oils.
Stearic Acid
It is rich in hydrating properties but occlusive and tends to clog pores for acne prone skin. Found in butters of cocoa, coconut, mango, mowrah, sal seed and shea, as well as neem, shea and tamanu oils.
Ricinoleic Acid
Found only in castor oil, ricinoleic acid is an omega 9 fatty acid with antibacterial and cleansing benefits.
Punicic Acid
It is an omega 5 fatty acid only found in pomegranate oil, which has repairing, anti-inflammatory and anti-aging properties.
Alpha-Linolenic Acid (ALA)
An omega 3 and an essential fatty acid that helps skin barrier health. High in black currant, perilla, flax/linseed, pumpkin seed, and soybean oils.
Eicosenoic Acid
It is an omega 9 with soothing emollient and permeation enhancing properties. High in jojoba and meadowfoam seed oils.
Behenic Acid
The behenic acid can be found in karanja and mooring oils. It has restorative, and highly moisturizing and conditioning properties, especially for hair.
Erucic Acid
High in abyssinian and broccoli oils, erucic acid can also be found in moderate amounts in jojoba and meadow foam seed oils. It is an omega 9, with a silky silicone-like feel for light hydration.
