Full Review
Most 'acne sheet masks' are hydrating sheet masks with a tea tree extract dropped somewhere in the middle of the INCI, a label redesign, and an implicit promise they'll help with breakouts. The reality is that you usually get a mildly antimicrobial essence diluted into oblivion, a short contact time, and no meaningful difference from any other calming sheet. The Tea-Trica Relaxing Mask is interesting because it refuses to play that particular game. SKIN1004 didn't just add tea tree to an existing sheet mask base — they replaced the base. The essence in this sheet is tea tree leaf water first, at a claimed 47,000 ppm, which means the entire vehicle carrying the actives is already doing antimicrobial work before any other ingredient joins the party. That's not a common formulation choice, and it's what justifies the mask's existence as a treatment step rather than a mood-and-hydration product.
The tea tree evidence base is worth understanding before you evaluate whether this approach actually helps. Multiple published clinical trials have examined Melaleuca alternifolia for its effects on mild-to-moderate inflammatory acne, with results showing antimicrobial activity against Cutibacterium acnes and meaningful reductions in lesion counts over 4-8 weeks of consistent use. Most of that research used 5% tea tree oil gel, which is higher than what you'd tolerate in a leave-on sheet, but tea tree water and leaf extract forms carry the same antimicrobial compounds at much lower concentrations and don't bring the essential oil's irritation risk. Using the leaf water as the base — rather than an essential oil drop — is how you take advantage of the evidence without the collateral damage.
On top of that base, the centella triterpene layer is doing exactly the same job it does across the rest of the SKIN1004 line. All four triterpenes — madecassoside, asiaticoside, asiatic acid, and madecassic acid — show up in the INCI, and they're here specifically to buffer the tea tree and the leave-on salicylic acid. That leave-on BHA dose, by the way, is the other thing that separates this mask from the average calming sheet. Salicylic acid at treatment-level exposure during a fifteen-to-twenty-minute dwell time is genuinely different from salicylic acid in a cleanser that rinses off in ten seconds. The sheet format keeps the BHA in contact with the skin long enough for it to penetrate sebum-filled follicles and support pore turnover, which is one of the few cases where sheet mask occlusion meaningfully changes an active's performance.
The supporting cast rounds out what's already a pretty complete acne-targeting formula. Niacinamide sits high enough on the INCI to be doing real work — sebum regulation, post-inflammatory mark support, barrier backup. Zinc PCA adds another sebum-control input. Panthenol, allantoin, and two weights of hyaluronic acid provide the hydration layer that keeps the mask from feeling stripping. The overall construction is unusually thoughtful for a sheet mask.
On skin, the sheet is lightweight and fits most faces reasonably well. The essence is cool and immediately calming on contact, and any sting from the salicylic acid is minimal — the centella buffering and the leave-on format handle it. Fifteen to twenty minutes is the right window; any longer and the sheet starts drying out, which reverses the benefit. After removal, there's plenty of essence left to pat into the neck and jawline, and the finish is clean and matte rather than dewy.
Honest limitations: this is not a sensitive-skin product. The tea tree plus salicylic acid combination is too much for reactive skin, and anyone with rosacea or eczema should skip it in favor of the Probio-Cica Nourishing Mask from the same brand, which uses the same cica philosophy but without the aggressive actives. It's also not pregnancy-safe because of the leave-on BHA, and it's not strictly fungal acne safe due to the PEG-40 hydrogenated castor oil in the formula — though tea tree is often considered helpful against malassezia, so the practical answer for fungal-acne users is mixed. And as with anything in the Tea-Trica line, this isn't a replacement for a dedicated treatment-strength acne product. It's a weekly SOS step that slots into an existing routine and reinforces it during active breakouts.
At around $4 per sheet or roughly $18-20 for a pack of 5, the value is fair but not spectacular. Sheet masks always cost more per milliliter than leave-on products, and the Tea-Trica Purifying Toner is a better daily-use value if you're picking one. But the mask does something the toner can't: it holds a treatment-level active stack on the skin for twenty minutes of occlusive contact, and during a breakout week that kind of concentrated exposure is genuinely useful. For acne-prone skin already using the Tea-Trica line, this is the natural weekly add-on. For anyone new to the brand, buy the cream and toner first, and reach for the mask when a breakout demands extra attention.

| Ingredient | Function | Evidence |
|---|---|---|
| Tea Tree Leaf Water (47,000 ppm) | Rather than plain aqua with a trace of tea tree, this mask uses tea tree leaf water as the essence base — a genuinely high-tea-tree format that delivers antimicrobial activity during the mask's dwell time without the sting of essential oil. | well-established |
| Centella Asiatica (Full Triterpene Panel) | The calming counterweight to the tea tree and salicylic acid — essential for keeping a leave-on sheet with this level of actives tolerable on already-reactive acne-prone skin. | well-established |
| Salicylic Acid | A small BHA leave-on dose that works across the 15-20 minute dwell time to support pore turnover — more effective in a sheet format than in a rinse-off mask. | well-established |
| Niacinamide | Sits high on the INCI to buffer the BHA and tea tree while supporting sebum regulation and post-mark fading — the quiet multitasker of the formula. | well-established |
| Zinc PCA | Reinforces the sebum-control side during the extended sheet contact — something a short toner pat doesn't have time to deliver. | promising |

Evidence
Science
The Science
Tea tree oil (Melaleuca alternifolia) has a substantial evidence base for antimicrobial activity against acne-causing bacteria, with published clinical trials showing results comparable to low-dose benzoyl peroxide for mild-to-moderate inflammatory acne, though with slower onset. Tea tree leaf water and leaf extract carry the same antimicrobial terpenes at lower concentrations and with significantly less irritation risk than the essential oil form, making them well-suited to leave-on sheet mask formats. Salicylic acid has decades of published evidence supporting its comedolytic and anti-inflammatory activity — it penetrates sebum-filled follicles thanks to its lipophilic character and supports corneocyte turnover. The 15-20 minute occlusive contact of a sheet mask is meaningfully different from the brief contact of a cleanser, giving BHA activity time to work on pore contents. The centella triterpene panel — madecassoside, asiaticoside, asiatic acid, and madecassic acid — has documented anti-inflammatory activity that buffers the effects of both tea tree and salicylic acid. Niacinamide provides sebum regulation, post-inflammatory mark support, and barrier function at 2-5% concentrations across published research. The combined mechanism of antimicrobial activity, keratolytic exfoliation, sebum regulation, and anti-inflammatory support is a coherent multi-pathway approach to managing active breakouts during a sheet mask treatment session.
Dermatologist Perspective
Dermatologists generally view sheet masks as adjunct products rather than primary treatments, but board-certified dermatologists note that short-contact occlusive formats can meaningfully enhance the delivery of water-soluble actives like salicylic acid and niacinamide. This type of treatment mask is commonly suggested as an occasional support step during active breakouts for patients already using daily acne routines, rather than as a standalone treatment. Patients with sensitive skin or rosacea are typically advised to avoid tea tree plus BHA combinations, even in short-contact formats.
Guidance
Usage Guide
How to Use
Cleanse and tone first. Remove the sheet from the sachet, unfold, and apply to clean skin. Adjust for fit around the eyes, nose, and mouth. Leave on 15-20 minutes — no longer, or the sheet will start pulling moisture from skin. Remove and pat the leftover essence into the skin, neck, and chest. Follow with moisturizer. Use 1-2 times weekly, or up to every other day during active breakouts. Do not use on broken or severely compromised skin.
Value Assessment
At around $4 per sheet or roughly $18-20 for a pack of 5, this mask sits in the middle of the K-beauty treatment sheet category. It's more expensive per milliliter than leave-on daily products from the same brand, which is inherent to the sheet format, but it's cheaper than most clinical-brand acne masks and carries a denser ingredient list. For existing Tea-Trica users, it's a reasonable SOS add-on. For daily maintenance, the Purifying Toner offers better cost-per-use.
Who Should Buy
Oily or combination skin dealing with mild-to-moderate active breakouts, especially users already in the Tea-Trica line looking for an intensive weekly treatment. Also a good fit for anyone who wants to try treatment actives in a lower-commitment sheet format before adding a daily product.
Who Should Skip
Sensitive skin, rosacea, or eczema. Skip during pregnancy. If your skin is severely dry or barrier-compromised, use the Probio-Cica Nourishing Mask instead — it's built for the opposite use case.

Background
The Why
SKIN1004 added the Relaxing Mask to the Tea-Trica line so breakout-prone customers could have an SOS weekly treatment in the same sheet format already popular across K-beauty. The sheet's long contact time is what makes carrying a leave-on BHA worth the effort.
About SKIN1004 Emerging Brand (2–5 years)
SKIN1004 launched in 2016 around Madagascar centella. The Tea-Trica Relaxing Mask brings the brand's acne-focused Tea-Trica line into a high-contact sheet mask format with a notably high tea tree concentration.

Myth vs. Reality
Myths
Myth
Tea tree sheet masks are too irritating to use during a breakout
Reality
The irritation risk comes mostly from tea tree essential oil at high concentrations, not from tea tree water or leaf extract. This mask uses the water and extract forms during a short 15-20 minute dwell time, which keeps the antimicrobial benefit without the sting.
FAQ
FAQ
How often should I use this mask?
Once or twice a week for maintenance, or up to every other day during active breakouts. Daily use is not recommended because of the leave-on salicylic acid dose.
How is this different from the Probio-Cica Nourishing Mask?
The Probio-Cica version is a calming, barrier-repair sheet mask with postbiotic ferments — built for sensitive, reactive skin. The Tea-Trica Relaxing Mask is targeted at acne-prone skin with tea tree, salicylic acid, and zinc PCA. Different jobs, different routines.
Is the Tea-Trica Relaxing Mask pregnancy safe?
No — it contains leave-on salicylic acid. Most dermatologists recommend avoiding leave-on BHAs during pregnancy. Use the Probio-Cica Nourishing Mask instead.
Is it fungal acne safe?
Not strictly. It contains PEG-40 hydrogenated castor oil, which some fungal acne routines exclude. Tea tree is often considered helpful against malassezia, but the overall formula isn't on standard safe lists.
Can I use it with other Tea-Trica products?
Yes — the mask slots naturally into the Tea-Trica routine. Use it 1-2x weekly at night after the Purifying Toner, then follow with the Tea-Trica B5 Cream as usual.
