Abstract

The invention relates to the incorporation of the low-molecular substance (compatible solute) .beta.-mannosylglycerate (firoin) extracted from extremophilic microorganisms and/or of derivatives of this compound, e.g. an acid, a salt or ester, in particular, also of the .beta.-mannosylglyceramide (firoin-A) in cosmetic or dermatological formulations for protecting skin from environmental influences and for improving the regenerability of the skin. Firoins (.beta.-mannosylglycera-te and .beta.-mannosylglyceramide) are, according to the invention, involved in the active cell protection of the cell-specific free-radical scavengers, of the proteins, of the antioxidants, of the DNA, of the cell membranes and of other cell constituents by virtue of the fact that they protect (thermally, chemically and physically) these against damaging environmental influences, e.g. UV radiation, IR radiation and environmental stress. For other active substances added to the cosmetic formulation, firoins can serve as co-solvents and penetration intensifiers in order to not only stabilize these in the cosmetic formulation but also to actively transport them into deeper skin layers.
