Protect pigmented skin against the sun with Institut Esthederm Sun Intolerance Photo Regul Lotion. The innovative formula is created with UV inCelluim technology helping the skin to defend itself against the ageing effects of UVA, UVB and free radicals. Photo Regul lotion protects the skin, preventing over-tanning of pre-existing dark spots and pigmentation. The sun care product visibly reduces the contrast between hyper-pigmented skin and the surrounding skin, resulting in a uniform, even-looking tan with long lasting results.
