Take the skin testThe COSRX Poreless Clarifying Charcoal Mask, the ultimate purifying and skin-perfecting mask that will transform your self-care night into a professional spa experience! This color-changing mask starts out pink and gradually turns gray, then finishes off in a beautiful white shade, leaving your skin looking and feeling amazing. The innovative formula of the COSRX Poreless Clarifying Charcoal Mask contains pink calamine capsules that instantly calm and control sebum, making it perfect for oily or acne-prone skin. The mask then releases a burst of charcoal that penetrates deep inside your pores to detoxify and clean, leaving your skin feeling refreshed and revitalized. As the mask dries, it tightens your pores and smoothens your skin's surface, giving you a radiant and flawless complexion.
Poreless Clarifying Charcoal Mask is a lightweight wash-off mask from COSRX, a brand based in Korea. Its job is UV protection, with the rest of the formula working on hydration and oil control. The ingredient list runs to 35 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Propanediol, Glycerin and Butylene Glycol, humectants that pull water into the upper layers of skin rather than sealing it there.
It is a mineral sunscreen, filtering with Titanium Dioxide. Between them those filters cover UVB and UVA II. They stop short of UVA I (340–400 nm), the deepest ageing wavelengths, so this is not a broad-spectrum filter system by the strictest reading. Every filter in the formula is photostable, so its protection does not fall away over the first hour in the sun — reapplication is still about sweat, water and rubbing rather than degradation.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Glycerin, Butylene Glycol and Betaine.
Oil control: High. Ingredients that moderate sebum or absorb shine, and here that comes from Silica, Kaolin, Charcoal Powder and Silica Dimethyl Silylate.
On richness alone it suits Balanced, Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on barrier support, brightening and tone, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after serums. Seal in your serums with it; in the morning, sunscreen still goes on top. It carries UV filters, so it belongs in your morning routine.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Regulates sebum production to reduce shine and greasiness
Calms redness, irritation, and inflammation for sensitive skin
Targets breakouts by reducing bacteria and unclogging pores
Helps unclog pores and reduce blackheads for clearer skin
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
Mineral filter system · does not reach UVA I
Strong UVB and short-UVA protection, but it stops before UVA I — a mineral formula leaning on titanium dioxide alone needs zinc oxide beside it for deep UVA.

COSRX, a brand based in Korea.
It filters UV with Titanium Dioxide (titanium dioxide).
Not in the strictest sense. Its filters stop short of UVA I (340–400 nm), the deepest ageing wavelengths.
Possibly. It filters with mineral UV filters, which sit on the surface and can leave a visible cast on deeper skin tones, especially at high SPF.
It contains none of the filters named in the Hawaii and Key West reef legislation (oxybenzone and octinoxate). "Reef safe" is not a regulated term, so treat that as a fact about the filter list rather than a certification.
Yes. Let it set for a couple of minutes before foundation so it does not pill, and reapply over makeup with a stick or powder rather than rubbing more in.
Every two hours of sun exposure, and immediately after swimming, sweating heavily or towelling off.
