Erno Laszlo White Marble Bright Hydrogel Mask. Ten minutes to radiance. This silky sheet mask feels indulgent, but delivers intensive results: instant hydration and powerful brightening. Radiance-boosting ingredients block excess melanin and free radicals to fend off dullness and dark spots. A perfect partner to your brightening skincare regimen, this gentle yet concentrated mask features: Soybean extract - long used in Asian skincare formulas - to naturally brighten the complexion. Vitamin C to clarify skin and deliver a high dose of antioxidants - while the protective mask keeps the vitamin's strength working for you longer. Antioxidant-packed yuzu fruit, a powerhouse citrus commonly found in Japan, to leave skin smoother, clearer and more radiant. How to Use: Unfold the mask and apply to freshly cleansed skin using the mouth and eye cutouts as a guide. After 10 to 15 minutes, remove and gently massage any remaining serum into the skin. Be sure to follow any daytime use with sun protection. For optimal results, use two to three times a week as part of your White Marble treatment ritual.
