title: Topical retinol and the stratum corneum response to an environmental threat.
abstract: The functional consequences of using topical retinol on skin have not been thoroughly studied so far. The aim of this open study was to compare two preparations containing either retinol or vitamin E, using biometric evaluations. Three methods, namely the sodium lauryl sulfate (SLS) corneosurfametry bioassay, the ultraviolet (UV) squamometry test and optical profilometry of the UV-induced wrinkling process, were used to assess some properties of the stratum corneum. The retinol preparation achieved better scores than the vitamin-E cream in all three tests and appears to improve the resistance of the stratum corneum against some chemical (SLS) and physical (UV) threats. It also limits UV-induced shallow wrinkling.
