Sébium Kerato+ is BIODERMA’s innovative concentrate with optimal exfoliating and anti-blemish benefits without compromising on skin tolerance. With a duo of AHAs & BHAs, Kerato+ works deep into the pores to clear breakouts, reduce marks and balance oil production to prevent recurrence. The skin is left mattified, hydrated and skin comfort is preserved. Salicylic acid refines skin texture and assists in unblocking the pores. Malic acid ester works deep into the oil glands to remove dead skin and thickened oil, while balancing oil flow and hydrating the skin. Malic acid ester is a derivative of malic acid. While malic acid in its original form has an acidity unsuitable for the skin, the ester used in Kerato+ is effective at skin pH meaning it maintains malic acid’s anti-blemish efficacy without compromising the barrier function. Combination of active ingredients with strong antioxidant power make up the Fluidactiv patent to biologically regulate sebum quality and durably prevent blocked pores. An imbalance in the composition of oil produced by the skin makes it prone to oxidization and thickening, a source of blemishes.
