Did you know that the potent skincare ingredient we know as Vitamin A was actually discovered in 1913 by an English biochemist named Frederick Gowland Hopkins?
Hopkins called this nutrient “factor A”, which later became known as Vitamin A. He was awarded the Nobel Prize in 1929 for this important discovery. 
Fast forward to 2017 and skin-loving vitamin A derivatives is one of the most important ‘go to’ ingredients in anti-aging as well as anti-acne skincare.
According to New York plastic surgeon Bryan G. Forley, “Vitamin A thickens and stimulates the dermis which is where collagen, elastin and blood vessels reside, which makes it an essential component of an effective anti-aging skin care regimen. Tretinoin and retinol are very useful and proven ingredients.”
Dr. Zein Obagi, Medical Director of ZO Skin Health, is a huge proponent of retinol and retinoids (vitamin A derivatives) because they are proven to boost collagen production, which reduces fine lines and wrinkles, and increases cell turnover to even skin tone and improve skin texture.
Tretinoin (pronounced Tret-in-oh-in) has been clinically proven to decrease fine lines, even skin color, improve texture and tighten pores. Retinol, which is the milder form of Tretinoin, also encourages skin cell turnover.
