sinsuru Watery Sulfur Pore Cleansing Powder

Ingredient analysis and how the ad lines read

Read on 2026-09-11

What is this product?

A 50g anhydrous powder cleanser from sinsuru, sold as a sulfur-based blemish cleanser and built, on its own label, as a mild enzymatic one. Corn starch carries the bulk; three amino-acid anionic surfactants at positions 2 through 4 do the cleansing; papain at 13 and gluconolactone at 11 supply enzymatic and polyhydroxy-acid exfoliation. Sulfur is real but sits at position 15 at a printed 100 ppm, and dimethyl sulfone at 12 is printed at 1000 ppm. The label carries no functional-cosmetic filing, no pH and no English INCI panel, and its statutory block exists only as an image on the brand storefront. Fits oily and congested skin; conditional for sensitive skin because of papain; poor for dry skin.

What makes it different?

Two things separate it on its shelf. First, it discloses levels at all: three of the 16 entries carry printed figures, which is unusual for a rinse-off and is what makes the sulfur claim checkable rather than a matter of belief. Second, it runs two exfoliating mechanisms in one rinse-off step, a protease at 13 and a polyhydroxy acid at 11, which is one more than the single-enzyme construction the powder format is usually built around. The corollary is the caution: that stacking is also why it is not a daily product for dry or reactive skin.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 1 with no dictionary entry, left in Korean.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

Did the ad claims hold up?

We checked 7 lines this product advertises against the ingredient list and public documents. 2 of them hold up. The rest are only partly right or have nothing behind them.
