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:
- 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.
- 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.
- 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.
- 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.
- 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.
- All skin types

Ingredients
Ingredients
(specific ingredients are subject to product packaging; core components listed below):
Key Brightening & Dark Spot-Lightening Ingredient (Vitamin C Derivative):
Sodium Ascorbyl Phosphate (SAP): A stable, low-irritation vitamin C derivative — inhibits tyrosinase activity (a key enzyme in melanin production), lightens existing dark spots, and prevents new pigmentation, while being gentle enough for most skin types.
Synergistic Brightening Ingredients:
Niacinamide (Vitamin B3): Blocks melanin transfer from melanocytes to keratinocytes, reducing the appearance of dark spots and evens skin tone; also strengthens the skin barrier to reduce moisture loss.
Glycyrrhiza Glabra (Licorice) Root Extract: Contains glabridin, a compound that fades pigmentation and soothes inflammation (common in post-acne marks), enhancing the mask’s dark spot-correcting effect.
Hydrating & Soothing Ingredients:
Sodium Hyaluronate (Multi-Molecular): High-molecular hyaluronate locks in surface moisture; medium/low-molecular hyaluronate penetrates deeply to replenish internal moisture, preventing dryness from vitamin C.
Centella Asiatica Extract (Cica): Reduces mild redness or tingling caused by vitamin C, calms sensitive skin, and repairs the skin barrier, ensuring a comfortable brightening experience.
Panthenol (Vitamin B5): Converts to pantothenic acid in the skin, enhances moisture retention, and soothes irritation, further reducing the risk of sensitivity from brightening ingredients.
Mask Sheet Material:
Ultra-Thin Microfiber: Soft, breathable, and non-irritating — the material has high serum-holding capacity and conforms to facial curves, ensuring even delivery of vitamin C and brightening ingredients without friction.
Preservatives & Stabilizers:
Phenoxyethanol (≤1%): A mild, EU-approved preservative that inhibits bacterial growth in the serum, extending the shelf life (24 months unopened) without irritating the skin.
Disodium EDTA: A chelating agent that binds to metal ions, preventing ingredient oxidation and maintaining the stability of vitamin C derivatives and niacinamide.
Harsh Substance-Free: Free of alcohol, artificial fragrances, parabens, mineral oil, sulfates (SLS/SLES), and synthetic colorants — meets "gentle brightening" standards, suitable for regular use with proper tolerance building.
How to Use
How to Use
Prepare the Skin (Day or Night, with Daytime Sunscreen): Clean your face with a mild cleanser and pat dry. Avoid using exfoliants (e.g., AHAs, BHAs) or retinol products on the same day to prevent over-irritation. If using during the day, apply sunscreen after the mask (vitamin C increases photosensitivity).
Apply the Mask: Tear open the sachet, unfold the mask, and align it with your eyes, nose, and mouth. Gently press to remove air bubbles, ensuring full contact with the skin — focus on dark spot areas by pressing the mask firmly to enhance ingredient absorption.
Relax & Absorb: Leave the mask on for 10-15 minutes (do not exceed 20 minutes, as prolonged contact may increase irritation). Remove the mask once the essence is mostly absorbed.
Massage & Lock in Nutrients: Gently massage the remaining serum into your face and neck until fully absorbed (no need to rinse). Follow with a moisturizer to lock in hydration and extend the brightening effect — this step is especially important for dry skin.
Recommended Frequency: Use 1-2 times a week initially to build tolerance; increase to 2-3 times a week once skin adapts. Avoid daily use to prevent potential irritation from vitamin C.
