Retinol concentrate with direct action on collagen fibers at 3 levels: repair, stimulation and protection. Suitable for mature skin accustomed to retinol.
 Treatment of skin aging and photoaging. Retinol is the only active ingredient that acts on collagen on 3 levels: repair (the damage caused to the fibers over time) + stimulation (of new collagen fibers) + protection (inhibiting collagenase).
 It also regulates melanocyte activity by reducing the patchy skin changes and stimulates the proliferation of keratinocytes of the epidermis (exfoliation). Nicotinamide reduces the transfer of melanosomes to keratinocytes (depigmentation), stimulates the production of new collagen, protects the skin from free radicals, regulates the synthesis of ceramides (moisturizing) and prevents inflammation of the skin.
