This Centella Asiatica Freeze-Dried Mask 520mg*5Pcs, Soothing & Nourishing, Enhances Skin Repair, Reduces Redness, for Sensitive Skin, Paraben-Free is a unique mask. You have to add water to it to start. I did find the mask to be slippery and it took a little time to pull it apart to place on my face. The mask was very cooling when wearing. It is a gentle mask and left my facial skin feeling healthy.
