NWTO never used still in packaging What it is: An intensive mask for extra moisture and smoothness that contains aloe vera and chamomile to help calm skin, too. What it does: Purslane, the key active ingredient, activates your skin's antioxidant system and protects sensitive cell membranes against free-radical attack. Kaolin, also known as China clay, lends silky-soft smoothness and suppleness to the skin. How to use: You can apply the mask generously to the skin 2–3 times per week after cleansing as an additional booster. Leave the mask on for about 10–15 minutes to let it take effect before rinsing it off with plenty of lukewarm water. Follow with your regular moisturizer.
