The Sun Shield Tint Broad-Spectrum SPF 50 Cool provides protection against harmful UVA/UVB sun rays that can lead to skin damage such as premature aging, fine lines and wrinkles, skin cancer and sun spots. Instead of going by skin tone, this sunscreen is designed to match your natural undertone and enhance your natural complexion. Use this Cool tint if you have naturally fair skin that is easily susceptible to sunburns, or if you have bluish veins visible on the forearms. The Nu-Derm Sun Shield SPF 50 is lightweight enough to be used daily and under makeup and other skin care products of choice.
