Vitamin A or retinol works as an anti-oxidant for the skin, disarming free radicals that cause tissue and cell damage. It smoothes wrinkles and lines gradually, improves moisture and elasticity, diminishes sun damage and provides glow to the skin complexion. In addition, vitamin A increases the skin’s cell turnover, while also boosts collagen, resulting in a more youthful overall appearance.
As well as working to diminish stretch marks, vitamin A assists the skin’s natural healing processes. This vitamin and its derivatives have displayed beneficial effects in controlling acne and in reversing skin damage caused by environmental factors.

Wrinkles and lines are gradually smoothed, moisture and elasticity increase, the complexion glows and sun damage is diminished. It increases the skin’s cell turnover, and increases collagen giving a more youthful appearance.
Vitamin A plays an important role in RNA synthesis which pro- duces new and healthy cells in skin. The epidermis is especially sensitive to vitamin A deficiencies since its basal layer continually generates new cells that keratinize and become the horny layer, the protective barrier. As a result of deficiencies, these cells prematurely die, harden, and plug the oil sacs and pores. Retinol exfoliates and unclogs pores; it acts on skin’s density and suppleness by regulating keratinizing and healing process.
It helps to restore damaged skin and improve the condition of rough and dry skin or skin with abnormal keratinization. This effect is based upon the action that vitamin A carries out on the basal stratum of the epidermis. Indeed, various studies have shown that applying the vitamin A locally achieves an increase in the mitotic activity of about 30%. By increasing cell turnover, dull surface cells are shed more quickly.
Vitamin A and its derivatives also have shown beneficial effects in controlling acne, psoriasis, neoplastic processes, and most recently, reversal in extrinsically aged skin.
