As part of the brand's Environmental Shield range, the Murad City Skin Age Defense Broad Spectrum SPF 50 PA ++++ truly goes above and beyond in protecting your skin. Its unique blend of ingredients works to defend the face, neck and chest areas against the five main pollutants that bombard us in modern life. The anti-oxidant rich Lutein protects against the blue light emitted by electronic devices; Zinc and Titanium Oxides deliver broad-spectrum protection against both UVA and UVB rays; Iron Oxides protect the skin from infrared radiation, and a specially designed Polymer Matrix prevents the adhesion and penetration of toxic pollutants in the air. These five types of pollutants contribute to the ageing of the skin, so in providing effective protection against them in this daily-use product, Murad City Skin Age Defense Broad Spectrum SPF 50 PA ++++ helps combat the signs of ageing. Quickly absorbed and with a non-greasy formula, this product boasts Vitamin C for a brightening boost, and is suitable for all skin types. It should be applied after your daily moisturiser.
