How often can I use it?

Once or twice a week suits a clay this concentrated, given kaolin sits second on the list at 120,000 ppm. If your skin runs oily right through and never feels papery the next morning, twice is fine. If it does feel papery, drop back to once and keep the layer thinner. Nothing is gained by reaching for it daily, and a lot of comfort is lost.

Is it really matcha, or just green tea?

Both, depending which surface you read. SOME BY MI's Korean ingredient panel names all four tea entries as green tea — water, leaf, milled powder and extract — and its imagery credits Boseong, Korea's best known tea county. Matcha is the name on the front of the tub and on the line as a whole; there is no separate matcha INCI on the back. So: verified Korean green tea, sold under a matcha name.

Will it leave my skin feeling dry?

It can, and that is worth planning around rather than being caught by. Clay at this concentration absorbs oil without discriminating, so the few minutes after rinsing count as much as the twenty before. Go straight into your toner and moisturiser while skin is still slightly damp. Skip it altogether in a week when your face already feels tight, and keep it off any flaking patches.

What is the BHA in this mask?

Two separate entries. Capryloyl salicylic acid is a laboratory-made salicylic acid derivative; white willow bark extract is the plant-sourced one. Both sit below the one-percent mark, judging by where they fall against the annotated figures around them. Read them as a mild smoothing contribution to something you wash away in twenty minutes, not as a leave-on exfoliating acid. If a BHA is already in your daily routine, space the two apart.

Can I use it if my skin reacts easily?

Carefully, if at all. Drying clay tugs at skin whatever else is in the pot, and the list SOME BY MI publishes on its own Korean site carries fragrance. Try a coin-sized patch along the jaw first, leave it on the full time, then look at that area the following morning. If your skin is currently broken, peeling or sunburnt, wait until it has settled before you start.

How does it compare to the toner and serum in this line?

They are three different jobs. The toner and the serum are daily leave-on steps you reach for morning and night. This one is weekly, and it works in a way neither of those can: a thick occlusive layer that dries hard and lifts away carrying the oil it has taken up. You do not need all three. Choose the mask if shine and a rough-feeling surface are what bother you.

PRODUCT DETAILS

Super Matcha Pore Clean Clay Mask is a thick, pale putty-grey clay you spread over a dry face and rinse away ten to twenty minutes later. SOME BY MI prints its two headline figures straight onto the ingredient panel rather than leaving them to the marketing: kaolin at 120,000 ppm, sitting second on the list behind water alone, and green tea water at 102,000 ppm just below the glycerin.

The tea appears four separate times — as water, as whole leaf, as milled powder and as an extract — and the brand's own product imagery credits Boseong, the county in South Jeolla best known for growing it. Around them sit bentonite, silica and a trace of Manicouagan clay, with centella asiatica extract, houttuynia cordata powder and tea tree leaf water lower down. White willow bark and capryloyl salicylic acid supply the BHA.

It is built for skin that reads shiny by mid-afternoon, catches on a cotton pad, and shows its pores most across the nose and centre of the forehead. The layer dries down firm and matte, so what you rinse off to is clean and faintly taut rather than cushioned. Moisturiser immediately afterwards is part of the step, not an afterthought.

Two notes worth having up front. This is a weekly or twice-weekly ritual rather than a nightly one. And where the toner and serum in the same Super Matcha line carry Korea's dual-function cosmetic registration, the mask is registered as an ordinary cosmetic.

Kaolin carries the absorbing
Green tea water, printed at 102,000 ppm
A smoother surface once rinsed
Centella and tea tree behind them

Key Ingredients

Pressed, pointed Camellia sinensis leaves partially magnified by a translucent jade glass lens on a warm oat surface.

Green Tea

Specific tea-leaf formulas may support hydration and a smoother, less shiny look.

Centella Asiatica

Helps soothe visible redness and support the skin barrier.

Concerns & Benefits

Your Concerns

1
Enlarged Pores
The openings across the nose, chin and forehead that look wider the closer you get to a mirror.
2
Oiliness
Shine that comes back over the T-zone a few hours after you have finished getting ready.

How To Use

1Use it once or twice a week, on a face that is completely dry.
2Cleanse, then dry your skin properly — the clay grips far better with no water beneath it.
3Spread a thick, even layer, staying well clear of your eyes and mouth.
4Wait 10 to 20 minutes, until the whole layer has gone matte and firm.
5Add lukewarm water and loosen it in small rolling motions, then rinse until clean.
6Follow immediately with toner and moisturiser. SOME BY MI recommends finishing the tub within twelve months of opening. Store it out of direct sunlight and press the lid down firmly after every use, because clay that has dried in the pot spreads badly. If your skin reacts easily, patch test along the jaw before the first full application, and keep the mask off broken or sunburnt skin.

Frequently asked questions

How long should I leave it on?

Ten to twenty minutes, and the timing is most of the trick. SOME BY MI's own directions say to wait until the layer has gone completely dry, which on a generous application lands closer to twenty than to ten. Sitting there longer does not make the clay work harder — it only makes rinsing slower and leaves your face feeling tighter than it needs to. Set a timer for the first couple of goes.
