Active substance-free, hydrophilic anionic cream (O/W cream) for external use. For less inflammatory forms of atopic eczema. Apply thinly 1-2 times/day to the affected skin areas. Preservation should be with sorbic acid 0.1% or methyl 4-hydroxybenzoate 0.06% and propyl 4-hydroxybenzoate 0.04% (possible)! Better: Sorbic acid 0.05%, potassium sorbate 0.07%, EDTA 0.05%.

Risk of sensitization: Cetylstearyl alcohol
