Perfect DD Cream SPF 20

Croda Inc

This Daily Defence Cream, or DD Cream, protects against harmful light wavelengths whilst also offering a uniform tint on the skin. This is achieved through the inclusion of Solaveil™ XT40W which provides protection against UVA, UVB and High-Energy Visible light damage as well as protection against the free radicals generated. By combining this with Venuceane™, which protects against cellular damage by InfraRed and free radicals, you can achieve broad spectrum protection from the sun and its photo-ageing effects.
