Featured Application

This work is of interest to both the cosmetics industry and skin care experts, as well as to companies producing or processing macro and microalgae, as they will find in this review an additional avenue for applying their derivatives in cosmetics and cosmeceuticals.

Abstract

The skin barrier is essential for maintaining the body’s internal homeostasis and protecting against harmful external substances; its impairment may cause different dermatological diseases. Algae compounds are used for skin care with the aim of preventing skin aging, improving hydration, and protecting against environmental aggressors. In this context, it can be assumed that these compounds (polysaccharides, lipids, phenols, etc.) may serve to strengthen the skin barrier, and therefore, the purpose of this review is to test this hypothesis. This review surveys the literature on the potential of algae-derived compounds in skin care, focusing on skin barrier repair, hydration, and emollience. From the review of published studies, it can be concluded that polysaccharides, phenols, carotenoids, and extracts from macro and microalgae can indeed be effective in skin barrier maintenance and recovery after injuries.
