A: Retinol is the most effective and proven ingredient to correct and prevent signs of aging in the skin. Retinol is derived from Vitamin A. It speeds up the skin’s cellular renewal process, meaning it instigates the skin’s own process of removing the top layer of dead skin and promoting new skin. During this process, the skin not only makes more collagen and elastin promoting firmer skin and the appearance of fine lines, but it also helps the skin to appear more even-toned and helps control breakouts. Retinol can cause dryness and sensitivity for the first few weeks of use. However, with continued use, this goes away and a more youthful appearance develops. Other important ingredients for anti-aging are Vitamin C/Ascorbic Acid which reverses and prevents oxidative stress that breaks down collagen. Also, peptides and hyaluronic acid firm and strengthen the skin cells, as well as promote collagen formation.
