I try to collect all the most important for cosmetic oils in a single article. Do you like the film of oil on the face or not - it does not matter. On a shelf with oil's Skin means to be present in each of us.
Whether dry oil needs, oily and sensitive skin?
Yes, more like. Cosmetic oils work with the lipid barrier of the skin, which protects us from germs and harmful external influences. Lipid barrier requires not only water, but also fatty acids.
Cosmetic oils moisturize dry skin and actively participate in the renewal of the epidermal cells and oily skin - make up for the lack of linoleic acid, which is lacking in the lipid barrier. That lack of linoleic acid is one of the main reasons that the owners of oily skin type are chronic rashes, acne and dermatitis.
In sensitive skin too disturbed lipid barrier, and it is strong. Because excessive skin reaction to normal external factors (wind, dust, cold or heat) is not possible with the normal protective barrier which will not pass through the corneocytes anything outside. It is obvious. So that moisture and free fatty acids such skin type is also needed, and they are there for cosmetic oils.
Details about the structure of the lipid barrier of the skin and as oils work with him, I have written previously. Duplicate link at end of article. I've got complete information on all unsaturated acids. This is important because with age, our skin is unable to produce their own fatty acids, their only cosmetic oils can make up the shortfall.
Oil serum or cream - is better?
Serum-based oils are good in that, along with fatty acids, fat-soluble vitamins enter the epidermis. As an example, different forms of vitamin E (tocopherols), which serve as one of the best antioxidants. And as we know, antioxidants are important in anti-aging care.
However, our lipid barrier in addition to the fatty acids needed more triglycerides, cholesterol, and ceramides. The luxury of serum lipid layer can not provide, but reducing nutrient creams - can.
Whether to include oil in the daily care?
I do not recommend. Yes, oil is useful. But often they can not be used, especially on a daily basis. Here's the thing: oil compensate for the deficiency of fatty acids, treat dryness and dehydration, but on the skin form a protective film anyway. The water from the surface of the skin in a natural way does not evaporate the water transfer into the deeper layers of the skin is broken, the result - dehydration due to the oils.
Better to use oil as needed or course. And yet! Then it should be replaced with a creamy texture.
How to apply oil?
Always it is necessary to exfoliate the skin (exfoliation or peeling roll from overcoat) before using oils. Otherwise clogged pores and will complain that comedogenic oil.
Depending on the percentage of fatty acid content can be dispensed after the application of oil without a cream. But mostly in the evening leaving the oil is applied by a nourishing cream. For example, camellia oil contains more other oils oleic acid (84%), which increases skin permeability to ingress of useful vitamin. This detail has already written, the link at the bottom of the article.
Should I believe the table comedogenic oils?
Part of the cost. But remember that even with a low index-comedogenic oil can clog the pores of the skin. The reasons are: the low degree of oil cleaning, its combination with other components or too high concentration of oils (fatty acids for many damaged lipid barrier - is also bad).
