Tonymoly Masterlab Mask Sheet
TONYMOLY's Masterlab line puts lab-formulated actives into single-use sheet masks: Glutathione for brightening, Caviar for firming, Collagen for bounce, Aquaget for deep hydration, and Vitamin C for an even tone. Each sheet is soaked in a concentrated essence and cut to fit close to the face, so the active sits on skin for 15-20 minutes instead of rinsing off in seconds. Pick the mask by the concern you want to treat that day and rotate them through your week.

How to pick a TONYMOLY Masterlab sheet mask
The Masterlab range is TONYMOLY's ingredient-led sheet mask line: each variant is built around one active (glutathione, caviar, collagen, Aquaget, or vitamin C), so you can match the mask to what your skin needs that day rather than guessing from a vague marketing name.
What's in the Masterlab line
Masterlab covers five main actives right now: Glutathione (also sold as a 20-sheet pack and a 10-sheet Shine Care variant), Caviar, Aquaget, Collagen (20-sheet pack), and Vitamin C (including a 5+5 bundle). Each sheet is soaked in an essence built around that one active, so the labeling on the box tells you exactly what you're getting.
Glutathione: the brightening pick
Glutathione is an antioxidant marketed for dulling and uneven tone. The Shine Care 10-sheet version is formulated to leave a visible glow right after removal, useful before an event when you want an immediate finish rather than a slow-build routine.
Caviar and Collagen: firmness and bounce
Caviar extract and collagen both target skin that feels loose or tired-looking. Caviar leans toward nutrient-dense firming, while the Collagen sheet (sold in a 20-pack) is aimed at plumping fine lines and restoring bounce after a long day.
Aquaget: the hydration pick
Aquaget is TONYMOLY's water-binding formula, built for skin that feels tight or dehydrated rather than dull or slack. It's the mask to reach for after sun exposure, air travel, or an air-conditioned office day.
Vitamin C: brightening and tone-evening
Vitamin C sheets are sold both as a single mask and a 5+5 ten-sheet bundle, which is the better buy if you're planning to use it two to three times a week for a stretch. It pairs well with Glutathione on alternating days for a brightening routine.
How to apply a Masterlab sheet
Cleanse and tone first, unfold the sheet along its printed guide lines, and press it flat starting from the center out so it sits without air bubbles. Leave it on for 15-20 minutes, then remove and pat the leftover essence into skin instead of rinsing it off.
How often to use these masks
Two to three times a week is a reasonable starting cadence for most of the line. The multi-sheet packs (the 20-sheet Glutathione and Collagen boxes, and the Vitamin C 5+5 bundle) are priced for that kind of regular rotation rather than a once-off treat.
Building a rotation across variants
Because each Masterlab mask targets one concern, a simple rotation works well: Aquaget or Vitamin C midweek for hydration and tone, then Glutathione, Caviar, or Collagen before the weekend for a brightening or firming finish. Stick to one sheet per session rather than layering two masks back to back.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Should I pick the Glutathione or the Vitamin C Masterlab mask for dullness?
Both target dullness but from different angles. Glutathione (sold as a single sheet, a 20-pack, and a 10-sheet Shine Care version) is built for a visible glow right after removal. Vitamin C (single sheet or the 5+5 bundle) works more on evening out tone over repeated use, so it suits a regular two-to-three-times-a-week rotation better than a one-off treatment.
What's the difference between the Caviar and Collagen Masterlab sheets?
Caviar extract is formulated as a nutrient-dense firming treatment, while the Collagen sheet (sold in a 20-pack) is aimed at plumping fine lines and restoring bounce. If your skin feels loose or tired-looking, Caviar is the closer match; if you're targeting visible fine lines, reach for the Collagen pack.
What does the Shine Care label mean on the 10-sheet Glutathione mask?
The Shine Care 10-sheet Glutathione mask is formulated for an immediate visible glow after you remove it, distinct from the standard single-sheet and 20-pack Glutathione masks, which are positioned for steady brightening over repeated use rather than an instant finish.
How often can I use TONYMOLY Masterlab sheet masks in one week?
Two to three sessions a week is a reasonable cadence, which is why the line sells multi-sheet packs: the 20-sheet Glutathione and Collagen boxes and the Vitamin C 5+5 bundle are all priced for that kind of regular rotation rather than a single occasional use.
When should I reach for the Aquaget mask instead of the others?
Aquaget is TONYMOLY's water-binding, hydration-focused sheet in the Masterlab line. Use it when skin feels tight or dehydrated, for example after sun exposure, a flight, or a day in air conditioning, rather than when the concern is dullness or firmness.
