SKINFOOD Black Sugar Mask Wash Off

Ingredient analysis and how the ad lines read

Read on 2026-09-22

What is this product?

A Korean rinse-off scrub mask built around undissolved black sugar, sold as a 120g jar. Sucrose is the first of 19 entries at a printed 35 percent and water is sixteenth, so the base is a nearly waterless lipid mass: candelilla wax, macadamia oil, lanolin, caprylic capric triglyceride, cetyl ethylhexanoate, shea butter and meadowfoam oil fill positions 4 through 11, with a quaternary modified clay thickener at 9. Exfoliation is mechanical rather than chemical; no AHA, BHA or PHA is named. The brand publishes both a named efficacy test, 48.84 percent on a keratin index after one use in 22 subjects, and a patch test summary sheet naming the test article, 32 subjects and a 0.021 irritation index. It is fragranced, with limonene and citral declared. Suited to flaking dry skin; the closed patch result does not cover the abrasion itself.

What makes it different?

Two things separate it. The abrasive is disclosed as a number rather than described, at 35 percent sucrose in a base whose water sits sixteenth of nineteen, so the grit is structural instead of decorative. And the brand publishes both an efficacy figure and a patch test summary sheet that names this exact product as the test article, which is a higher standard of disclosure than a footnote naming only an institution.

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.
