The OOTD Dark Spot Vitamin C Serum Brightening Mask is a Korean sheet mask that drenches skin in a Vitamin C serum to brighten a dull, uneven complexion and soften the look of dark spots. Each vegan, Lyocell sheet clings closely to deliver a concentrated dose of Vitamin C, Vitamin E and Glutathione, leaving skin looking more radiant, smoother and hydrated after a single 15-minute session.

Why This Vitamin C Mask Works

Dull, uneven skin often comes down to a tired surface, dehydration and patches of excess pigment that make the complexion look blotchy. The OOTD Dark Spot Vitamin C Serum Brightening Mask floods the skin with antioxidant-rich serum in one concentrated sitting, so brightening actives and moisture are pressed right where you want them. The thin Lyocell sheet holds the essence close to the skin for even, efficient delivery, then leaves a fresh, non-sticky finish.

Ideal For

This mask suits all skin types, including sensitive skin, and is a smart pick for anyone battling dullness, uneven tone or dark spots left by sun and blemishes. It is a quick, affordable way to add a brightening step before an event or on tired evenings. Vegan, cruelty-free and made in Korea, the OOTD Dark Spot Vitamin C Serum Brightening Mask is easy to slot into any routine.

Every sheet is soaked in a brightening serum built around three antioxidants:

• Vitamin C (Ascorbic Acid): a brightening antioxidant that helps even the look of skin tone and boost radiance.

• Glutathione: an antioxidant that supports a clearer, more luminous-looking complexion.

• Vitamin E (Tocopheryl Acetate): helps defend skin against environmental stress while adding moisture.

Niacinamide, hydrating glycerin and soothing allantoin round out the formula, so skin feels comfortable, plump and refreshed rather than tight. The serum absorbs without any sticky residue, making it easy to layer into your routine.

For best results, use the OOTD Dark Spot Vitamin C Serum Brightening Mask as follows:

1. Cleanse and tone your skin, then unfold the sheet and smooth it evenly over your face, avoiding the eyes and mouth.

2. Relax for 15 minutes (up to 20) while the serum absorbs.

3. Remove the sheet and gently pat any remaining essence into the skin. Follow with moisturiser if you like. Use 2 to 3 times a week.
