By now, you’ve probably heard about retinol and its multiple skin benefits. It’s no secret that retinol is currently in the spotlight, but you should know that this holy grail ingredient is here to stay. Let’s delve into the basics you need to know about retinol and how to incorporate it into your nighttime skincare routine for healthier skin.
What is retinol and how does it work on the skin?
Retinol is a form of retinoid derived from vitamin A. The way the skin metabolizes retinol is very simple. In the skin, retinol is first oxidized to form retinal. Retinal is then oxidized to generate retinoic acid that binds to certain proteins in the cytoplasm of cells, a step necessary to allow retinoic acid to enter the nucleus of cells and bind itself to DNA. It is the action of retinoic acid on DNA that accounts for all its biological effects on skin.
