topicSilicon Skin Hydration Randomized Trial
claimWhen SC integrity is compromised, by reduced epidermal lipids or NMF (as in NMF‐deficient xerotic skin) [], intrinsic aging changes in keratinization and lipid production [], or environmental insults, TEWL increases and water‐holding capacity falls [].
