What it is: An effective serum with an active, 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.
