With antioxidants, is a separate one needed when so many products contain it now?
I can see how this could be confusing. The answer is that it’s still better to use a separate, high concentration antioxidant because the quality and concentration of antioxidants in most sunscreens, moisturizers, makeup, etc. is just not high enough to do much good and the word “antioxidant” is so loosely used. The term has become almost meaningless without knowing exactly “what” and exactly “how much.” Hope this makes sense. Dr. I
