INDUFENCE^®, thanks to its richness in purified alisma peptides, acts on both mechanical and immune biological barrier. On the one hand, it increases the cohesion of the upper layers of the epidermis through the membrane network of tight junctions. On the other hand, it stimulates the innate immunity receptor and thus the production of anti-microbial peptides. INDUFENCE^® improves hydration and global skin quality.
