Vitamin A is the single most proven go-to ingredient for improving everything from acne, wrinkles and collagen synthesis to hyperpigmentation. Even today, following the advent of peptides, peels and stem cells, vitamin A and its retinoid-derivative family continue to reign as the gold standard of skin care, particularly in treating photodamage.
How Vitamin A works...Retinols are converted by the skin to retinoic acid, where they become active. This derivative actually includes several chemical compounds—commonly referred to as retinoids. Vitamin A can attach itself to skin cells, normalizing their function and getting them to behave like younger, healthier versions of themselves by softening fine lines and wrinkles, boosting collagen and elastin, accelerating cellular turnover, and smoothing the skin.
Although it takes longer to work Retinyl Palmitate is one step back from Retinol. The upside is that it does not cause the reactions and irritations that stronger retinoids do including itching, redness, and peeling.
When incorporating vitamin A to a regimen, it is important to eliminate exposure to the sun and always use a mineral-based SPF 30 or higher following a Vitamin A treatment.
