A brightening sheet mask for dull, uneven skin and for the marks left behind after spots have healed. It is the tone-focused member of Abib's Gummy Sticker line, pairing vitamin C with glutathione in a cream-type essence rather than relying on acids.

Uneven tone is largely a pigment problem, and this formula intervenes at more than one point in the pigment pathway. A vitamin C derivative works as an antioxidant and inhibits tyrosinase, the enzyme that starts melanin production. Glutathione acts further along, shifting synthesis away from darker eumelanin. Niacinamide handles the final stage by limiting transfer of finished pigment granules into surrounding skin cells. Addressing initiation, synthesis and transfer together is more complete than any single brightening active manages alone. Liposomal centella keeps the formula tolerable, since brightening actives can sensitise, and panthenol with sodium hyaluronate maintain hydration.

The essence is cream-based rather than watery, so skin is left soft as well as bright — a sensible choice the night before an event.

Key ingredients

• Vitamin C derivative — antioxidant that inhibits tyrosinase, in a form more stable than pure ascorbic acid.
• Glutathione — an antioxidant tripeptide that shifts melanin synthesis towards lighter pigment.
• Niacinamide — blocks pigment transfer to surrounding cells and supports the barrier.
• Liposomal centella asiatica — encapsulated for delivery; keeps a brightening formula from tipping into irritation.
• Panthenol and sodium hyaluronate — hold water so brightened skin does not look dry or flat.

How to use

1. Cleanse and apply toner, leaving the skin damp.
2. Apply the sheet evenly, avoiding the eye and nostril openings.
3. Leave on for 10 to 15 minutes.
4. Remove and pat the remaining essence into skin and neck.
5. Follow with moisturiser. In the morning, sunscreen is essential.

Recommended frequency

• Dull or uneven tone — two to three times weekly.
• Post-inflammatory marks — twice weekly alongside a daily brightening serum and SPF.
• Normal skin or pre-event — once weekly.
• Timeline — immediate radiance from hydration; measurable change in pigmentation takes eight to twelve weeks, and only with daily sunscreen, since unprotected UV regenerates pigment faster than any topical fades it.

Best suited to

Suits all skin types dealing with dullness, uneven tone or post-blemish marks. Very sensitive skin should introduce it gradually, as vitamin C derivatives can sting on compromised skin. It will not lighten skin beyond its natural tone, and deep dermal melasma needs clinical treatment.

Good to know

Abib describes the formula as fragrance-free and suitable for sensitive skin. Vitamin C actives are light- and heat-sensitive, so store sachets flat, cool and out of direct sun. Do not combine with an AHA, BHA or retinoid in the same session — occlusion under a sheet mask amplifies those actives. Any brightening routine is undermined without daily SPF. Single use only; patch test if you have reacted to vitamin C before.
