Barrier Cream creates an invisible barrier that seals the skin and protects it from discoloration from pigments and the damage of chemicals. It is non-greasy, non-toxic and can be applied to any area of the skin. Merely wash your hands, dry them thoroughly, massage a generous portion of Barrier Cream into the skin, and allow to set for 4 to 5 minutes. Alcone Barrier Cream comes in a lotion form and guards the skin against Acetone, Ammonia, Peroxide, and most hazardous chemicals.
