An expert in skin biology, Bioderma research has innovated and created Sensibio Tolerance+: the dermatological treatment which durably increases the skin’s tolerance level while respecting the skin’s natural biology. At the heart of this treatment is Neurocontrol, an exclusive complex made up of a tetrapeptide and a combination of soothing active ingredients. Neurocontrol reduces the hyperexcitability of the skin's nerve fibers and regulates the biological mechanisms responsible for the intolerance. The feelings of tightness and discomfort are soothed. The skin regains its original comfort. Enriched with Sodium PCA, Sensibio Tolerance+ fortifies the skin's barrier function and provides optimal moisturizing.
