Reduces sagging. Increases the skin's resistance to sagging. Ultra-concentrated rich emulsion that promotes the penetration of redensifying active ingredients. With age, the skin loses its thickness, becoming more fragile, dry, and less elastic. This intensive cosmetic treatment, combined with daily nourishing care, combats sagging skin by toning, reducing sagging, and achieving more structured, compact, and firmer skin. It achieves a lifting effect from within, thanks to its stimulating function in the production of extracellular matrix components. How to use: Always apply before cream to your face, neck, and décolleté morning and night, allowing it to penetrate for a few seconds, as a treatment enhancer for the Be+ Redensifying Nourishing Cream for Mature Skin. Avoid applying this serum to the eye area. Complete your usual Be+ care with products from the Be+ Ultra Concentrated Pre-Treatments range, which will provide additional properties.
