Cosrx Sheets

The One Step pads are daily-use treatment pads you wipe on and leave - they deliver actives like salicylic acid or humectants without rinsing and take about 30 seconds to apply. Sheet masks are a 15-to-20-minute intensive treatment used one to three times per week, where you press a saturated fiber or hydrogel sheet against your full face and then remove it. Pads are part of your daily routine; masks are a weekly add-on.

The Original Clear Pad contains salicylic acid (BHA), which is an exfoliant that can be drying if used too frequently on already-dry skin. If you have dry skin and want a daily pad, the One Step Moisture Up Pad is a better fit - it skips the BHA and focuses on hydration instead. If you're committed to the exfoliant effect of the Original Clear Pad, using it every other day rather than daily helps minimize over-drying.

The main difference is the active ingredient. The Original Clear Pad uses salicylic acid for exfoliation and pore clearing. The Green pads use centella asiatica as the focus ingredient, which calms redness and supports barrier recovery rather than exfoliating. The Green pads are better for sensitive or reactive skin, post-sun exposure, or on days when your skin is stressed and you want to support it rather than exfoliate it.

Most people use eye patches two to three times per week for ongoing hydration and firming support, or daily for a short intensive period when under-eye dryness or puffiness is a priority. The 60-sheet box (30 pairs) lasts about two to three months at three-times-per-week use. There's no harm in daily use if your skin tolerates it - the formula is gentle enough for repeated use on the delicate under-eye area.

For the under-eye specifically, hydrogel patches generally conform better than a flat sheet mask cut to fit the area. Hydrogel material has more give, so it stays in contact with the curved contour under the eye and reduces the chance of air pockets forming that would reduce contact with skin. The Advanced Snail Hydrogel Eyepatch is purpose-built for the eye area, so it's a more targeted option than cutting down a full-face sheet mask.

Hyaluronic acid comes in different molecular weights that penetrate to different depths in the skin. Triple hyaluronic acid means the formula uses three molecular weight variations: high-weight molecules sit on the surface and reduce water loss, medium-weight molecules enter the upper layers and provide immediate plumping, and low-weight molecules reach deeper layers for more lasting hydration. The three-weight approach delivers hydration across different skin layers simultaneously rather than just the surface.

Centella asiatica (cica) has anti-inflammatory properties that can reduce visible flushing and irritation within the 20-minute treatment window. Most people notice their skin looks calmer directly after removing the mask. However, for redness caused by rosacea or persistent inflammatory conditions, a single mask session won't address the root cause - it's more useful as a calming step after exposure to sun, wind, pollution, or any treatment that temporarily sensitizes skin.

Close the lid fully between uses - pads dry out when air circulates through the jar. Some people press a piece of plastic wrap over the pads before closing the lid for extra protection. Store the jar away from heat and direct sunlight, which can evaporate the solution faster. If pads start to feel less saturated toward the bottom of the jar, they're still usable but may need an extra press before swiping to redistribute the solution that has pooled at the base.

Yes, but watch your acid load. The Original Clear Pad contains low-concentration BHA, so on days you use it you should avoid layering additional AHAs, BHAs, or retinol in the same routine step. If you use a vitamin C serum, apply it on non-pad days or in the morning when the pad was used the night before, since vitamin C and BHA can cause irritation when stacked. The Moisture Up and Green pads have no exfoliant actives and can layer more freely with other serums.

COSRX is a South Korean skin-care brand known for simple, functional formulations that focus on a small number of well-studied actives per product rather than long ingredient lists. The brand is formulated and manufactured in Korea to MFDS standards. COSRX is among the most widely exported Korean skin-care brands internationally and has a long track record in the acne-care and hydration categories specifically. All COSRX products on skinsli are sourced directly to ensure authenticity.

Don't throw it away - the remaining serum in the pouch is the same formula as what's saturating the mask. After removing the mask, pour the residual serum from the packet into your palm and pat it over your face and neck. You can also use it on your hands and elbows. This gives you extra product from each mask and means you're not wasting any of the actives.
