Derma serum based on colloidal silver solution, organic willow extract, aloe vera, panthenol, allantoin, hyaluronic acid and essential oils of ginger and lavender, provides soothing support for acute skin irritations. Silver ions and silver nanoparticles achieve a strong antimicrobial effect and eliminate pathogenic microorganisms that accumulate on the hair and skin of dogs and thus enable other active ingredients to exert their potent effect in a completely clean environment. Aloe vera gel cools, hydrates and regenerates damaged skin, maximally relieving itching. Organic willow extract moisturizes and softens damaged skin, and is suitable against inflammatory processes and other skin problems. Panthenol and allantoin hydrate to the maximum, thus promoting skin regeneration. Hyaluronic acid binds moisture and thus improves skin elasticity.
