What it is: An effective serum with a plant-based complex to help rebalance and calm irritated skin and aid in reducing redness and burning.What it does: This serum helps strengthen skin's natural defenses, minimizing the skin's sensitized reaction. Purslane, a key active ingredient used in this range by Dr. Sturm, activates the skin's own antioxidant system, calms inflammation and protects sensitive cell membranes against free-radical attack. The serum is ideal for rebalancing skin that is stressed as a result of sun exposure, sleep loss, jet lag, air conditioning and exposure to smoke or environmental pollution. How to use: Use as a concentrated serum before applying your moisturizer. Screw the pipette into the bottle. After cleansing, apply the serum. After it absorbs, apply a moisturizing cream. To reduce skin sensitivity, apply regularly in the morning and/or evening over an extended period of time. Use once or twice per day. 1 oz.
