Vitamin A thins the skin
Studies show that vitamin A compacts the stratum corneum and thickens the epidermis, which runs completely contrary to the idea that it has a thinning effect. It influences the genes that cause epidermal stem cells to grow into fully functioning keratinocytes and mature into healthy layers of the epidermis. Vitamin A increases the growth of the basal layer which is why the epidermis becomes thicker and therefore more tolerant to damaging environmental effects.
“You can thicken the epidermis by up to 100 per cent compared to not using vitamin A”
