Retinol or vitamin A is one of the most important vitamins for the human body, being involved in the healthy development and functioning of all cells. Without this compound, cells can’t reproduce normally therefore cellular differentiation is altered. Vitamin A deficiencies result in vision impairments, digestive problems, skin conditions and a weakened immune system.
From all its benefits, retinol is most appreciated for its ability of maintaining skin’s elasticity and smoothness and for the role it plays in building the body’s natural barer against pathogens that can enter the organism through skin.
Retinol effects on skin
This vitamin is widely used in anti-aging creams, in sun lotions, night creams, moisturizers and gels, in anti-wrinkle creams and products for wounds care. In order to be incorporated in these products, vitamin A is taken from two main sources: animal-based products and plant-based products, in this case the extracted substances being called carotenoids.
Beta-carotene found in carrots in only one example of carotenoid which is broken down to vitamin A once entering the organism. But vitamin A takes many forms and not all of them are created equal so their effects on skin are different. In order for this vitamin to exert its action and have significant effects on skin, it has to be turned into retinol and then into retinoic acid.
Retinoic acid, although the most effective form of this vitamin, can cause skin irritation and rash, so its use in quite limited when it comes to the production of topical creams and ointments. Fortunately, the body does have the needed enzymes to convert retinol to retinoic acid inside cells, so this is why skin care products contain retinol and not retinoic acid.
As for the effects of this compound on skin, it’s worth mentioning:
• Its ability of reducing acne symptoms and providing relief from psoriasis manifestations,
• Its efficiency in preventing premature aging and the formation of warts,
• Its ability of stimulating cell regeneration and growth.
How Rezage-by-Yelena uses retinol in creams
Rezage is among the renowned producers of anti-aging retinol creams incorporating retinol as their main active ingredient. But why do they use this particular compound and not other substances? Mainly because retinol is a very strong antioxidant, which means it neutralizes free radicals that are known to damage skin and accelerate aging.
This natural process is associated with a slowed down cell turnover, which means the organism finds it harder to eliminate dead, thick and sun damaged skin cells from the surface and to replace them with new, fully functional ones. The direct consequence is a dull looking skin, thicker than normally, with enlarged pores, age spots and blotchiness due to sun damage.
Retinol has the great advantage of having a small enough molecular structure for penetrating skin layers and improving the appearance of the lower ones, where cell turnover can be increased through exfoliation. Through its anti-oxidant properties, retinol rejuvenates the skin, restoring its healthy and radiant aspect.
Moreover, this substance improves collagen production in the deeper skin layers, improving cell structure and maintaining skin’s elasticity and firmness. But for all these beneficial effects to be exerted, retinol has to penetrate deep into the skin and this can’t be done unless the substance is mixed with other compounds that are able to transport it through the outer skin layers.
Retinol is fat-soluble, not water soluble, so it needs to be transported towards the layers of adipose tissue right underneath the skin in order to be effective. If it stays on top of skin, it loses properties therefore becomes ineffective in improving skin’s appearance. On the contrary, it’s broken down to those mentioned substances which can cause skin irritation and dermatitis.
So how can retinol be delivered into the skin without invasive treatments, you might ask? The answer and the right solution come from Rezage, which uses an innovative approach to this problem: it incorporates retinol molecules into very tiny spheres called microcapsules, through a process called microencapsulation.
The sub-micron spheres used in this technique are so small they can easily penetrate skin and reach into the deeper layers, where retinol is released progressively and exerts its magic effect from inside out. What’s the result? A firmer and softer skin, free of wrinkles and fine lines, visibly rejuvenated; an evenly pigmented skin that has no warts, age spots or acne signs!
