What is Retinal?
Retinal has demonstrated an ability to outperform retinol* by working 11 times faster and having a lower risk of irritation compared to regular Vitamin A products.
Although both retinol and retinal are forms of vitamin A, there are key differences that distinguish them. The main difference is in how they convert when applied to the skin. Retinol requires two steps to become retinoic acid, which our skin can absorb, while retinal requires only one step. This makes retinal faster acting, more stable, and more effective in delivery compared to retinol.
