Cosrx Mask

COSRX masks divide into three distinct use cases. Sheet masks are single-use cotton or hydrogel sheets soaked in essence, worn for 15-20 minutes. Overnight sleeping masks are leave-on treatments applied as the final skincare step before bed and rinsed off in the morning - they provide a longer period of ingredient contact and a sealing effect. The One Step Green Calming Pad is a pre-soaked cotton pad used as a toner-step substitute, combining cleansing residue removal with active ingredient delivery in one wipe.

Choosing the right format depends on how much time you have and what degree of intensive treatment you need. Sheet masks suit evening routines with 20 free minutes; overnight masks work best for sustained nourishment during sleep; the calming pad is the quickest option for a daily active step.

The Pure Fit Cica Calming True Sheet Mask uses centella asiatica (cica) extract as its lead ingredient. Centella is one of the most studied botanical ingredients for skin-calming and wound-healing applications, and it appears in multiple product names in the COSRX lineup. The sheet mask format delivers cica and supporting soothing ingredients under occlusion, which increases absorption compared to a standard toner application.

This mask suits skin after extractions, after laser or peel treatments (once the initial recovery window has passed), after sunburn, or on any day when the skin feels reactive and tight. The calming effect is typically noticeable during and shortly after the 20-minute application window.

The Hydrium Triple Hyaluronic Water Wave Sheet Mask delivers three forms of hyaluronic acid in one mask session. Different molecular weights of hyaluronic acid work at different skin depths: lower molecular weight reaches deeper layers while higher molecular weight works at the surface. The triple-HA approach targets hydration across the full depth of the outer skin rather than only at the surface.

This mask is the right choice on days when skin feels tight, dehydrated, or dull from lack of moisture. It also primes skin well for occasions where a plump, fresh appearance matters - before photography, travel recovery, or winter dryness peaks.

The PDRN Hydrogel Mask (3 sheets per pack) uses polydeoxyribonucleotide (PDRN) alongside hyaluronic acid in a hydrogel format rather than a cotton sheet. Hydrogel masks adhere more closely to the skin contours and transfer ingredients more efficiently than cotton alternatives. PDRN is a skin-repair and hydration active derived from salmon DNA that has attracted interest in Korean skincare for its cell-regenerating properties.

The hydrogel format is also cooler and more comfortable during wear than cotton sheets, which makes it a popular choice for evening use after a long day. The 3-sheet pack makes it practical as a multi-use treatment to compare against the cotton alternatives in the range.

The Full Fit Propolis Honey Overnight Mask is one of COSRX's signature products. Propolis is a resinous compound produced by bees with proven anti-inflammatory and antioxidant properties in skincare. Combined with honey (a natural humectant), the overnight mask creates a nourishing, seal-in treatment that works during the hours the skin is in repair mode. It is available in 60ml, which provides approximately 15-20 overnight applications for a consistent twice-weekly or nightly treatment course.

The texture is soft and non-tacky by morning when the skin has absorbed the formula. Rinse off gently in the morning cleansing step. It suits dry or compromised skin, or as an intensified treatment during dry seasons.

The Ultimate Nourishing Rice Overnight Spa Mask uses rice extract - a traditional East Asian brightening ingredient - as its lead active in a sleeping mask format. Rice contains niacinamide precursors and other compounds that support skin tone evening and surface renewal during the overnight skin repair cycle. The spa mask positioning indicates a richer, more nourishing texture than a standard sleeping pack.

This mask is suited to skin that needs both brightening and barrier nourishment simultaneously - typically dry or stressed skin with an uneven tone. It pairs well with a preceding hyaluronic acid or essence application to build hydration layers underneath before sealing with the mask.

The AC Collection Blemish Care Sheet Mask (26ml single-use) is COSRX's acne-concerned mask offering. It delivers blemish-targeting actives in a sheet mask format suited to use during active breakout periods or for maintenance after clearing. The AC Collection sub-line from COSRX is the brand's acne-focused range, known for including ingredients like tea tree, niacinamide, and mild acids in formulas designed for congested skin.

This mask is the appropriate pick when the primary concern is controlling excess sebum or reducing the appearance of blemishes, rather than brightening or barrier repair.

The One Step Green Calming Pad (135ml) is a pre-soaked cotton pad used in place of a toner after cleansing. A single pad wipe removes residual cleansing product and applies calming active ingredients in one step. The "green" in the name references the calming botanical blend, which aligns with the cica/centella approach across the COSRX range. This product suits daily use by people who prefer a simplified routine or want to replace a separate toner and essence step with a single active delivery format.

The 135ml bottle contains enough pads for regular daily use over several weeks. It is particularly effective as a one-step option for travel or mornings when routine time is short.
