This innovative light-textured sun serum by Dr. Barbara Sturm doubles as skincare and provides a truly broad-spectrum SPF 50 protection against both UVA (photoaging) and UVB (sunburn) rays. An active complex of Vitamin E and Beta-Glucan protects the skin from oxidative damage, while Purslane, an anti-aging powerhouse, helps calm the skin and reduce the visible signs of irritation.
