Skin Care Products: Age-Appropriate Cosmetics.

Abstract

In order to maintain skin in "good condition" one can use cosmetic products. Importantly, those skin care products should fulfil specific requirements for specific life phases and specific skin conditions. In this review, we focused on 2 different age groups - namely, infants and the elderly - as well as on 2 specific skin conditions occurring in both age groups - very dry skin (Xerosis) and hyperhydrated skin (diaper rash). The goal in both conditions should be to maintain skin surface in its physiological acidic state, which is in turn crucial for the permeability barrier function, stratum corneum integrity/cohesion and antimicrobial defense. Skin care products formulated with an effective buffer system at a more acidic pH, for example 4, may be the best option to improve the acid mantle and skin barrier function and thus keep the skin in "good condition."
