OOTD Dark Spot Vitamin C Serum Mask (10)

OOTD Dark Spot Vitamin C Serum Mask (10)?is a 10-sheet set of targeted brightening masks designed to 'lighten dark spots + even skin tone + boost radiance' through a stable vitamin C serum formula, addressing pigmentation and dullness without excessive irritation. Its core features are:

1. Stable Vitamin C Complex: Contains a gentle yet effective vitamin C derivative (e.g., sodium ascorbyl phosphate) �� unlike pure vitamin C (ascorbic acid), this derivative is non-irritating and stable (resists oxidation in air), ensuring consistent brightening and dark spot-lightening efficacy.
2. Dark Spot-Targeted Essence: Infused with niacinamide and licorice root extract �� niacinamide blocks melanin transfer to skin cells, enhancing dark spot-lightening effects; licorice root extract soothes inflammation and further fades pigmentation, creating a 'multi-layered brightening' synergy.
3. Skin-Fitting, Serum-Rich Sheet: The ultra-thin, breathable microfiber sheet conforms tightly to facial contours (especially targeting dark spot-prone areas like the cheeks, forehead, and nose) �� each mask holds 28-32ml of concentrated serum, ensuring vitamin C and brightening ingredients fully penetrate targeted areas.
4. 10-Sheet Flexible Care Set: The 10-sheet size supports a gradual brightening routine (1-2 times a week for 5-10 weeks) or short-term intensive care (3-4 times a week for 2-3 weeks, for experienced users) �� adaptable to different skin needs and schedules.
5. Gentle Brightening Formula: Free of alcohol, artificial fragrances, parabens, mineral oil, and sulfates (SLS/SLES) �� paired with centella asiatica extract to soothe mild irritation from vitamin C, balancing efficacy and skin comfort for regular use.
