Glycerin
Glycerin is added to PoxClin® for its ability to moisturize the skin. Humectants are substances
that increase the water holding capacity of the skin; examples of such are lactic acid, urea, PCA
and glycerin25. Glycerin is an endogenous humectant of the outermost layer of the skin, the
stratum corneum (SC), meaning it is naturally present. It is included in the SC’s natural
moistening factor (NMF)26, preventing skin from severe drying.
