Retinol, a vitamin A derivate, is the most important anti-age activator. It prevents the formation of wrinkles and improves the strengthening and healing of the skin. Retinol is widely used in the cosmetic industry.
The activator is shown as the ideal combination of efficacy and tolerability, unlike another vitamin A derivate, retinol acid, which is very effective, but also very irritating.
In its natural state, Vitamin A is derived from two sources: as retinol, which is found in foods (liver, egg, milk); or as a pre-retinol, also called provitamin A, which belongs to the group of carotenoids (which are located in various vegetables and fruits).
Retinol reduces the formation of wrinkles
The retinol serum effect begins dismantling the keratinocytes that are completely on the surface of the skin, which allows retinol to pass through to the skin itself. Stimulating fibroblasts (skin cells), Retinol promotes the synthesis of the collagen and elastin, the auxiliary fiber of the skin.
And the result is the reduction of wrinkles and firmer skin. Its action against wrinkles is based primarily on the acceleration of cell activities: thus assists the regeneration and healing of the tissue in the basal layer. Participating in the creation of balance and renewal of the cells, retinol plays such an important role as far as the problem of keratinization (thickening of the skin).
That mainly improves the condition of the aged skin, that’s characterized by slow cell renewal. Many studies have shown that using the retinol, skin elasticity has been enhanced and formation of wrinkles prevented by the action of ultraviolet radiation.
It means retinol can ‘tell’ skin cells how to behave and even look – like a typical, younger cell. When the skin is damaged by the sun, this communication is extremely beneficial because sun-damaged skin creates an unhealthy, abnormal and inflexible skin cells.
Cures acne-prone skin
Retinol also affects the proper functioning of the sebaceous and sweat glands. It is therefore sometimes used in the treatment of acne. In fact, stopping the hyperkeratinization (too much thickening) of the acne-prone skin, it prevents the formation of blackheads. Reducing the accumulation of dead cells on the skin surface, retinol avoids creating blackheads and pimples and the clogging of the pores.
Retinol penetrates well and does not cause the skin irritation. Regular use of retinol improves the appearance of the skin and reduces wrinkles, but these results are lost as soon as the person stops using it. Like all the vitamin derivates, the retinol too cannot be well preserved, because it is very easily oxidized and changes in contact with oxygen.
