Near the bottom of this cleanser's product page, after the mud-to-foam poetry and the exosome complex, TIRTIR prints a sentence I have not seen from a skincare brand before: due to the high clay and mud content, temporary redness may appear after rinsing. It is an honest thing to write, and it is also a clue. Clay does not redden skin on its own; a potassium-soap base with a lot of mineral particles in it does. Read the ingredient list and the warning explains itself. Palmitic, stearic, lauric and myristic acid at positions three to seven, potassium hydroxide at ten: that is soap, made in the tube. Kaolin fifth, bentonite eighth, hectorite, diatomaceous earth and a clay from a Canadian impact crater further down: that is the stated seven percent of mud. Together they make a cleanser that scrubs and strips in the same motion, and the brand, to its credit, tells you so.
For the skin it is built for, that is not a criticism. Squeeze out the terracotta paste, spread it over a damp face, and it sits cool and heavy like a thin clay mask; add water and rub, and it works up into a thick, creamy, faintly gritty foam that rinses to a genuinely matte finish. On an oily, congested T-zone at the end of a hot day it is one of the more satisfying washes I have used this year. Sodium methyl cocoyl taurate and lauryl betaine, the mild surfactants blended into the soap, keep the after-feel from squeaking, and a little glycerin and a long tail of hyaluronate forms soften the rinse. Blackheads look lighter after a couple of weeks because the clay is lifting the surface oil that oxidises in them. Shine holds off for hours.
The cost of that thoroughness is the same as with every potassium-soap cleanser. Fatty-acid soaps sit at a pH well above skin's, lift the skin's own lipids along with the sebum, and on anything but resilient oily skin leave tightness within minutes and flaking within a fortnight of twice-daily use. The brand's own suitability list, oily or combination skin, is the right one, and I would narrow it further: oily skin once a day in the evening, combination skin two or three times a week alongside something milder. Dry, sensitive, rosacea-prone and barrier-damaged skin should not be near it, and the redness warning is the reason why. A pink flush that fades in a few minutes is friction and mild irritation; one that lingers or stings is the cleanser telling you it is stripping rather than purifying.
Then there is the Porexel story, which this cleanser wears like every other product in the line. Glycolic, lactic, malic and tartaric acid appear in the second half of the list, in a soap-based wash-off with under a minute of contact and a pH that keeps them out of their active form; they are there so the tube can join the line's resurfacing narrative, and they do not exfoliate. Nicotinamide adenine dinucleotide and nicotinamide mononucleotide sit twenty-sixth and twenty-seventh, in what the brand calls an NMN·NAD+ Exosome complex at 1,000 ppm, its lowest dose in the range. NMN and NAD+ have no good evidence for topical benefit even when left on the skin; in a cleanser they are rinsed away with the foam, and the exosome is an unnamed plant fraction rather than anything cellular. The line's serum at least leaves its coenzymes on the face. Here they are in the drain thirty seconds after they arrive. Jasmine extract, lower down, adds a whisper of scent and a fragrance-family allergen the oily-skin audience will mostly shrug off.
A practical note on using it well, because the difference between a good clay soap and a sore face is mostly technique. Damp skin, not wet, so the paste sits rather than slides; thirty seconds as a mask on the T-zone only, not the cheeks; small circles with fingertips rather than a scrub; and then a rinse that goes on longer than feels necessary, because clay particles lodge in the creases beside the nose and are what leave the pink patches the brand warns about. A hydrating toner within a minute and a proper cream after it, and the tightness never gets a chance to set. Follow that, two or three nights a week, and the cleanser behaves.
At twenty-two dollars for 150 millilitres the price is above what a clay soap needs to cost, and the difference is the branding. Used two or three times a week, as most skin should, the tube lasts three to four months, which brings the monthly figure down to something sensible; used daily it is gone in two. The tube itself is fine, though the paste is stiff enough to want a firm squeeze and the cap collects a little dried clay.
The Porexel line launched on 4 September 2026 and has no reviews yet on any market, so this is a reading of the list rather than a report of months of use. TIRTIR is a Seoul brand that has been on international shelves since 2023 and whose products pair sound formulation with whatever ingredient is trending, and this tube is the pattern with an unusual footnote of honesty. Buy it if your skin is oily and tough, you like a clay wash that foams, and you will follow the brand's advice to rinse thoroughly and keep a moisturizer close. Skip it if your cheeks have ever felt tight after a foaming cleanser, or if you were paying for the coenzymes, which leave with the foam.
