Guinot Hydrazone Serum hydrates each area of the face according to its specific needs
Because not all areas of the face have the same water needs, Guinot Hydrazone Serum offers a personalized solution thanks to its intelligent hydration concept. This new generation serum replaces the Hydra Cellulaire Serum and goes further by optimizing hydration where the skin truly needs it.
Its innovative, fresh, and light texture transforms upon application to promote rapid penetration of active ingredients deep into the epidermis. Immediately, the skin is intensely hydrated, more supple, and visibly more radiant.
Suitable for all skin types, even sensitive, it acts on overall dehydration while respecting the specificities of each area of the face: T-zone, cheeks, contours.
