展开A formula enriched with waterproof active ingredients that resists water and moisture in even the hottest temperatures. The Guerlain Tan Booster: derived from the thousand-year-old Mediterranean carob tree, it helps stimulate the natural production of melanin. The tanning process is activated before, during and even after exposure. The tan is intensified, prolonged and enhanced day after day. Lamellar powders and a unique combination of pigments form an ultra-fine film that mirrors the natural finish of each person's skin, perfectly following the face's contours. Application is entirely streak-free. *In vitro test on ingredient. 0.4 oz. Made in France
