The invention is related to compositions which can be used as dermal formulations for supporting the skin to restore normal conditions in case of e.g. irritated skin, or to support medical therapy of skin with atopic dermatitis symptoms, atopic dermatitis, psoriasis or related diseases (e.g. accompanied by distorted barrier function of the skin and microbial load). The compositions of the invention can be used for dermo-cosmetic products but also for pharmaceutical/-medical products, depending on the composition and the additional actives incorporated (cosmetic actives or drugs). The invention is based on the synergistic effect of metallic particles, in particular silver particles (such as microsilver, nanosilver) and lipid particles (lipid nanoparticles or lipid microparticles). As alternatives to silver particles, other metallic particles (e.g. zinc, copper) or nanocrystalline actives can be incorporated (e.g. replacing the anti-oxidative silver by anti-oxidative nanocrystals of plant molecules such as hesperitin). This leads to combinations of lipid particles with nanocrystals for dermal use.
