Can antioxidants in skincare products become pro-oxidants?
Yes, under certain conditions, antioxidants can become pro-oxidants and contribute to oxidative stress rather than preventing it. This paradoxical behavior depends on the concentration of the antioxidant, the presence of metal ions, and the type of antioxidant used. However, skincare formulations are typically designed to stabilize these compounds and prevent pro-oxidant activity.
