Spanish firm Vytrus Biotech has developed a 100% natural active ingredient that protects the cutaneous microbiota involved in fighting the signs of photoageing, at the same time it stimulates the antioxidant and photo-protecting microbial metabolism under sun exposure
The skin microbiota plays a key role in skin homeostasis and the skin microbial ecosystem evolves with age.1-3 Furthermore, the microbiome is highly relevant regarding the regulation of skin functions when the skin is exposed to sun radiation.
Various microorganisms of the skin microbiota have been identified for having especially important functions in protecting the skin in front of UV radiation: Staphylococcus epidermidis, Micrococcus luteus, Bifidobacterium spp. and Malassezia furfur. 4,5 The metabolism of these microorganisms contributes in the protection of our skin against the exposure to sun radiation.
S. epidermidis can produce short chain fatty acids (SCFA) which inhibit the sun erythema, reducing the pro-inflammatory cytokine IL-6, as well as increasing the collagen expression in fribroblasts,6 thus improving the skin firmness and elasticity
