Clay masks and cleansing gels (including dual-action cleanser/mask formulas) are commonly listed for oily and acne-prone skin because they focus on oil control, pore cleansing, and acne-fighting ingredients.
Under-eye masks typically hydrate and plump the delicate under-eye area, brighten tired-looking eyes, reduce the appearance of fine lines, de-puff, and help revitalize dark circles.
Hydrating sheet and hydrogel masks are typically left on for about 15–30 minutes. Spot treatments or some under-eye patches often recommend shorter times, around 10–20 minutes.
Reviewers often report visible reduction in the appearance of pores and oiliness, that these masks remove pore debris and blackheads, and that skin feels smoother, softer, and clearer after use.
Charcoal peel-off masks are described as detoxifying, drawing out impurities and excess oil and removing surface debris from pores. They often require a thicker application and a longer drying time so the mask peels off properly.
