The SOS hydra gel mask is a refreshing, moisturising, and calming gel mask which helps to soothe dry and irritated skin. The combination of humectant ingredients and NMF components contribute towards improving the moisture of the skin. This complex assists to retain moisture in the stratum corneum and helps to maintain suppleness of the skin. Contains Chicory root extract and Caesalpinia Spinosa Gum with a superficial tightening and flash effect. SOS hydra gel mask has a very good skin compatibility.
