Etude Therapy Mask

A sheet mask functions as an occlusive wrap: it holds the saturated essence against your skin for a concentrated period, slowing evaporation and giving active ingredients time to absorb. The thinner the sheet, the more closely it conforms to the face, which means less air exposure at edges and dips around the nose bridge or jaw.

Conventional non-woven sheet masks are cut at 0.3mm or more. ETUDE's Therapy Air Mask sheet is cut at 0.2mm, which gives it a near-transparent appearance when applied. The sheet also tends to stay moist longer because there is less fabric to dry out. For most skin types, a 15-20 minute application is enough; going longer risks the dry sheet pulling moisture back out of the skin.

The Therapy Air Mask line covers nine active focuses. Here is how to match them to your current skin situation:

• Hyaluronic Acid - for skin that feels tight or dehydrated at any point in the day. Hyaluronic acid draws water to the upper dermis layers; this variant is a good everyday mask for combination or dry skin types.
• Ceramide - for compromised or sensitized skin that has been stripped by over-cleansing, retinol, or weather changes. Ceramides are lipids that form part of the skin barrier; this variant helps reinforce that barrier rather than just adding surface moisture.
• Collagen - for mature or dull skin that has lost elasticity. Collagen in a sheet mask works primarily as a humectant at the skin surface rather than penetrating deeply; it adds temporary plumpness and smoothness.
• Snail - for skin in recovery. Snail secretion filtrate contains a mix of glycoproteins, hyaluronic acid, and antimicrobial peptides. This variant is frequently recommended for use after minor breakouts or after a harsh skincare routine.
• Aloe - for calm, immediate soothing. Aloe vera gel has a high water content and mild anti-inflammatory compounds. It works well the day after sun exposure or after any activity that leaves the skin warm and reactive.
• Tea Tree - for congested or breakout-prone skin. Tea tree oil has well-documented antibacterial properties. This variant is not a spot treatment but a full-face calming step that can reduce surface redness during a mild breakout period.
• Green Tea - for antioxidant protection and light hydration. Green tea extract contains polyphenols (catechins) that help neutralize oxidative stress. This variant suits oily or combination skin that does not need heavy moisture but benefits from daily antioxidant input.
• Lemon - for uneven tone and dullness. Lemon extract provides vitamin C and citric acid, both of which have brightening properties. This variant works best as a periodic brightening treatment rather than daily use.
• Pearl - for radiance and luminosity. Pearl powder contains amino acids and trace minerals; this variant is popular as a prep step before events or photography when a lit-from-within appearance is the goal.

Getting the most from a sheet mask comes down to timing and prep, not effort.

1. Cleanse and tone first. Apply the mask to clean, slightly damp skin. Residual makeup or sunscreen will create a barrier between the essence and your skin.
2. Open the pouch carefully. Each mask is folded in the pouch with an inner liner. Unfold it fully before placing it on your face.
3. Align from the eye holes outward. Place the mask at your eye openings first, then smooth down and outward to the edges of your face. The 0.2mm sheet will conform closely; use your fingertips to press out any remaining air pockets.
4. Leave on for 15-20 minutes. Do not exceed 20 minutes. Once the sheet starts to dry out, it can begin to pull moisture back from the upper skin layers.
5. Remove and pat in the remaining essence. Do not rinse. Use your fingertips to pat the remaining serum into your skin until absorbed. Follow with your regular moisturizer to seal everything in.

A sheet mask replaces your serum step on the days you use one. The layering logic is: cleanser, toner or essence, sheet mask (15-20 min), then moisturizer. Do not apply a separate serum underneath the mask; you are effectively layering two high-concentration products on top of each other, which can cause pilling or overwhelm sensitive skin.

For most people, two to three masks per week is sustainable. If your skin is in a recovery phase, such as after starting a retinol or after a chemical exfoliation, daily use of the Ceramide or Snail variant for a few days is a common approach to help the barrier while continuing the rest of the routine.

If you use the mask in the morning, apply it before SPF and makeup. The essence from the ETUDE 0.2mm masks absorbs relatively quickly after patting, so there is usually no wait time before applying sunscreen.

Each Therapy Air Mask variant names its primary active in the product title, but the base essence across the line shares common supporting ingredients: water, glycerin (humectant), butylene glycol (moisture-retention aid), and a variety of plant extracts depending on the variant. The sheet itself is a non-woven cellulose or bio-cellulose material cut to the 0.2mm specification.

Hyaluronic Acid in the HA variant refers to sodium hyaluronate, the salt form that has better penetration into the upper skin layers than the full-molecular-weight version.

Ceramide in the ceramide variant is typically ceramide NP or ceramide AP, the two most common ceramide types in Korean formulations. These are identical in structure to the ceramides found naturally in the skin barrier.

Snail Secretion Filtrate is standardized in Korean cosmetics regulation; products labeled with snail must meet minimum concentration requirements, so you are getting an active amount, not a trace ingredient.

Tea Tree is listed at concentrations effective for mild antibacterial action. For more targeted spot treatment, a dedicated tea tree serum or spot gel would be a higher-concentration option.

The Therapy Air Mask line is formulated for general use, but some variants are better suited to specific skin types:

• Dry skin: Hyaluronic Acid and Collagen variants are the primary choices. Ceramide is a strong secondary option if the dryness is linked to a compromised barrier rather than just low water content.
• Oily or combination skin: Green Tea and Tea Tree variants are lighter and suited to oily zones. Lemon works well for combination skin with uneven tone.
• Sensitive skin: Aloe and Ceramide are the gentlest options. Avoid the Lemon variant if your skin reacts to citrus acids.
• Normal skin: Any variant is appropriate. Rotating across Green Tea, Hyaluronic Acid, and Pearl throughout the week is a common approach for maintenance.
• Mature skin: Collagen and Snail are the most targeted options. Pearl works well as a finishing step before going out.

Each ETUDE 0.2 Therapy Air Mask pouch is sealed and single-use. Unopened pouches are stable at room temperature for the standard 36-month period common to Korean sheet masks. Store them away from direct sunlight and heat; high temperatures can degrade the actives in the essence, particularly vitamin C-containing variants like Lemon.

Once opened, the mask must be used immediately. There is no way to reseal the pouch and preserve the remaining essence after the sheet is removed. If you have extra essence in the pouch after applying the mask, you can use it on your neck or the backs of your hands rather than discarding it.

Refrigerating sealed pouches is optional but popular, particularly for the Aloe and Tea Tree variants, where the cool temperature adds to the soothing effect on application.

The ETUDE 0.2 Therapy Air Mask is available both as individual pouches and as variety sets on skinsli. Individual pouches let you stock up on the one or two variants that work best for your skin. Sets make sense when you want to trial multiple variants before committing, or when you want different options for different days of the week.

The 20ml fill per pouch is a full single-use dose for the face, with enough left over for the neck in most cases. This is in line with standard Korean sheet mask sizing. Masks with less than 20ml tend to leave the sheet partially dry before the recommended time is up.

If you are buying for a gift, the variety sets covering three or more variants are the most practical choice, as they let the recipient find their preferred active without committing to a full box of one type.
