NotoxMD is recommended for people with wrinkles and/or fine lines. Every skin type is different, so while some people with sensitive skin will have no issue using NotoxMD, some might, although this has only been in a minor amount of cases in our experience. If you have sensitive skin, Dr Sharad recommends the “patch test” where you first apply the serum to the inner elbow and see if there is a reaction before assessing whether to apply it to your face.
