As we age, our skin increasingly shows the signs of environmental and emotional stress, including fine lines and wrinkles, rough skin, uneven skin tone, brown spots and acne. A successful means of treating these conditions has been to accelerate the natural process in which dead cells are sloughed off to reveal new skin. Salicylic acid has been an effective exfoliating agent commonly found in products that address these skin imperfections. In-office peels have helped boost the effect of over-the-counter products. Yet the quest for better, faster and more enduring results has continued…


After many years spent trying to maximize the beneficial effects of salicylic acid, La Roche-Posay’s research division discovered LipoHydroxyAcid (LHA). This revolutionary molecule is created by grafting a fatty chain onto salicylic acid. This facilitates superior interaction with the skin, promoting faster cellular regeneration, unclogging pores and  allowing for greater penetration which means more accurate, targeted and enduring action.


La Roche-Posay has incorporated the amazing exfoliating and purifying properties of LHA in combination with glycolic and salicylic acids in their Biomedic products and treatments. Especially after the summer season when regular use of sunscreen mixed with the humidty might have created congestion, roughness or breakouts, to the rescue is Biomedic’s LHA Cleansing Gel, Solution and Serum to provide effective correction and daily maintenance. They can be used every morning and night, offering dramatic results that include reduction of dark spots and fine lines, softer skin and clearer complexion.
