Retinal is the “big brother” molecule of the better known anti-aging superstar, retinol. While retinol needs two metabolic conversion steps to reach the active form, retinoic acid (aka tretinoin), retinal is the direct precursor only one conversion step away from the active form the skin cells understand. It is estimated that retinal can convert more than 10x faster to retinoic acid than retinol, making retinal an outstandingly effective member of the retinoid family (vitamin A family).
Once converted, retinal helps the skin cells to produce more collagen and other structural elements, making the skin more youthful, firm and elastic. It also speeds up the renewal process of the upper skin layers making it smoother and more even. A-Game is a smart-aging must-have, but it is also useful as an adjacent product for fading pigmention, as well as helping acne-prone skin.
In terms of strength and knowledge, we would compare our 0.05% retinal serum to a mid-strength retinol product (typically in the 0.2-0.5% range), but with less irritation potential and possibly quicker results.
