Vitamin A for your skin helps prevent and improve photo aging as well as hydrate the skin and is an indispensable factor in the maintenance of healthy epithelial growth and maturation.
Vitamin A for your skin is used in different forms: retinyl palmitate, retinyl acetate, retinol, retinaldehyde and beta-carotene.
The walls of the skin cells are not easy to penetrate. Vitamin A as retinyl palmitate, retinyl acetate and retinoic acid can enter the cell through passages called retinoid surface receptors.
Once inside the nucleus of the cell vitamin A can produce the following changes:
- It affects the genes of the skin cells so they can grow and look more normal
- It is a normaliser of DNA
- It increases the growth of the basal layer thickening the skin
- It helps the skin heal faster
- It induces the production of healthy collagen
- It increases the secretion of natural moisturising factors allowing the skin to retain more water.
- It improves the blood supply to the deeper layers of the skin increasing the nourishment and oxygenation of the skin.
- It absorbs UV rays and free radicals protecting the skin from sun damage
- It repairs ultra-violet damage
- It prevents tissue wasting and the destruction of collagen
Unfortunately every time we go into sunlight, our vitamin A levels, not only in the skin, but also in the blood, are depleted. The UV-A and UV-B radiation destroys the vitamin A, C and E in our skin. Vitamin A takes 7 days to be replaced through diet. Here is where the Environ skin care range plays a vital role because topical vitamin A moisturisers replace vitamin A in the skin within 3 hours.
Most adults, specially those which skins that have been depleted of proper levels of vitamin A for a long period of time, need to slowly adapt to vitamin A moisturisers. The retinoid receptors of the skin cells are lost with lack of use, thus if high levels of vitamin A are applied to the skin the excess will be spilt in the intercellular space and cause a reaction.
A reaction to vitamin A is characterised by dryness and flaking of the skin, redness, inflammation, and mild breakouts. If a reaction occurs you should slow down usage of vitamin A. You can do that by using the product less often (i.e. twice a week instead of everyday) or go back to a moisturiser with a lower level of vitamin A. Any reaction will clear as soon as you stop using the cream, the skin will never be permanently damaged.
Slow acclimatisation to vitamin A will ensure that more retinoid receptors are created without overwhelming the cells and causing a reaction. Environ moisturisers use a step-up system that slowly builds up the receptors in the cells’ walls ensuring optimum results.
