COLLECTION: Toleriane / Toleriane Kerium DS Concentrate is a daily moisturizing and soothing face care product for skin prone to seborrheic dermatitis and sebo-squamous skin. A new scientific discovery: in people showing signs of seborrheic dermatitis, the mircrobiome tends to be unbalanced due to an abnormal proliferation of a micro-organism: Malassezia. This micro-organism, combined with an impaired barrier function and high sebum production, contributes to the development of irritation and signs of seborrheic dermatitis. For optimal anti-squamous efficacy, Toleriane Kerium DS Concentré compensates for microbiome imbalance with a micro-organism cultivated in La Roche-Posay Thermal Spring Water: Aquae Posae Filiformis. Immediately: skin is moisturized and soothed. The cutaneous barrier is protected. After 1 month: skin comfort is restored. Localized flakiness and itching are reduced*. Anti-relapse efficacy (flaking and redness): 6 weeks between flare-ups**. Optimum tolerance: Alcohol-free. Care tested on skin prone to seborrheic dermatitis. *Clinical study, 41 subjects, twice-daily use. **Clinical study, 41 subjects, twice-daily use, results at 4 weeks persisting 6 weeks after product discontinuation.
