Tonymoly Master Lab Sheet
TONYMOLY's Master Lab sheet mask series covers 25 in-stock variants on skinsli, each built around one active ingredient rather than a general blend. Charcoal and Aqua Jet handle oil and hydration extremes, Sika and Cica calm redness and irritated patches, Collagen and EGF lean into firming, and Hyaluronic Acid, Ceramide, and Glutathione round out hydration, barrier care, and brightening. Most sheets sell as a single mask, with a 20-sheet Ceramide pack for anyone who wants to keep one formula in steady rotation. Because each mask is built around a single named ingredient, it is easy to pick one for a specific concern instead of guessing at a blended formula's main active.

Picking a TONYMOLY Master Lab sheet mask by concern
The Master Lab line takes a different approach from most sheet mask ranges: instead of a blended "brightening" or "hydrating" formula, each mask is named after the single ingredient it's built around. This guide breaks down the 25-piece assortment on skinsli by concern so picking a sheet takes less guesswork.
How the Master Lab line is organized
Each sheet in this collection carries one named active in the title: Charcoal, Collagen, EGF, Sika, Cica, Hyaluronic Acid, Ceramide, Glutathione, and Aqua Jet. The sheet material and soak time stay consistent across the range, so the main variable when choosing is the ingredient rather than the format.
Oil and pore-focused sheets
The Charcoal mask is the pick for an oilier T-zone or a day after heavy makeup, since charcoal is used here to draw out surface buildup rather than add moisture. It pairs well with a lighter moisturizer afterward instead of a heavy cream, since the point of this sheet is decongesting rather than hydrating.
Redness and sensitivity sheets
Sika and Cica both target irritation and redness, drawing on centella-adjacent ingredients that are common in Korean skincare for calming a reactive complexion. Either works well after sun exposure, light exfoliation, or any day the skin feels tight or flushed rather than simply dry.
Firming and anti-aging sheets
Collagen and EGF lean toward firmness and elasticity claims, making them a fit for anyone building an anti-aging step into an existing routine. These sit better as an occasional treatment mask than a daily habit, since the goal is a concentrated dose of the active rather than routine hydration.
Hydration and barrier sheets
Hyaluronic Acid and Aqua Jet both push toward deep surface hydration, useful after air travel or in dry, heated indoor air. Ceramide leans more toward barrier support, so it suits skin that feels dry AND sensitive rather than just thirsty, and it's the one variant sold in a 20-sheet multipack for regular use.
Brightening with Glutathione
The Glutathione mask is built around a brightening active often paired with an even-tone routine. It works well rotated in alongside a vitamin C serum or brightening moisturizer rather than replacing either, since a single sheet mask session gives a shorter-lived boost than a daily leave-on product.
How to use a Master Lab sheet mask
Apply to cleansed, dry or slightly damp skin, smooth out air bubbles from the center outward, and leave on for the time printed on the packet, typically 10 to 20 minutes. Remove before the sheet dries out completely, then pat the leftover essence into the skin instead of rinsing it off, and follow with a moisturizer to seal it in.
Building a rotation across the line
Because each sheet targets one concern, a small rotation works better than committing to a single variant: Cica or Sika on irritated days, Hyaluronic Acid or Aqua Jet on dry ones, and Charcoal when pores feel congested. The 20-sheet Ceramide pack is the practical choice for whichever variant becomes a steady weekly habit.

FAQ
Frequently asked questions
What's in the TONYMOLY Master Lab sheet mask collection?
25 in-stock sheet masks, each built around one named active: Charcoal, Collagen, EGF, Sika, Cica, Hyaluronic Acid, Ceramide, Glutathione, and Aqua Jet, with most sold as single sheets and Ceramide also available as a 20-sheet pack.
Which Master Lab sheet mask suits oily or congested skin?
The Charcoal mask is built for oil and congestion, drawing out surface buildup rather than adding moisture. It works best followed by a lighter moisturizer instead of a heavy cream.
What's the difference between the Sika and Cica sheet masks?
Both target redness and irritation using centella-adjacent actives, so they're close in effect. Either is a reasonable pick after sun exposure or light exfoliation when the skin feels reactive rather than simply dry.
Should I rinse off a Master Lab sheet mask after removing it?
No rinse needed. Leave the sheet on for around 10 to 20 minutes per the packet, remove before it dries out, then pat the remaining essence into the skin and follow with a moisturizer.
Why is only the Ceramide mask sold as a 20-sheet pack?
Ceramide supports the skin barrier and is meant for regular, ongoing use, so it's stocked in a 20-sheet multipack for anyone folding it into a weekly routine, while the other actives are treatment-style sheets sold individually.
Which sheet mask in this line is best for brightening?
The Glutathione mask is the brightening-focused option, best rotated alongside a vitamin C serum or brightening moisturizer rather than used as a replacement for a daily leave-on product.
