Nanodispersions have a monolayer membrane of pure phosphatidylcholine and facilitate the penetration of lipophilic active ingredients and supply the skin with linoleic acid, which is essential for repairing the skin’s barrier function. Nanoparticles fuse with the skin’s lipid barrier and deposit their active ingredients into the epidermis. dermaviduals® nanoparticles are fluid nanoparticles in contrast to solid nanoparticles and therefore do not have any adverse effect.
