DESCRIPTION

The COSRX Arbutin Discoloration Hydrogel Mask is a results-focused treatment designed to visibly fade dark spots, hyperpigmentation and post-acne marks while delivering a surge of deep hydration. Alpha-arbutin, a gentle brightening agent derived from the bearberry plant, works by inhibiting melanin production at the source to reduce existing pigmentation and prevent new spots from forming.

The hydrogel format sets this mask apart from traditional sheet masks by adhering closely to every contour of the face, creating a seal that drives actives deeper into the skin and prevents evaporation. After just one use, skin feels intensely hydrated and looks noticeably brighter.

HOW TO USE
  1. Cleanse and tone your skin, then carefully apply the hydrogel mask to the face, smoothing out any air bubbles.
  2. Leave on for 20 to 30 minutes. Do not exceed 30 minutes.
  3. Peel off and gently massage any remaining essence into the skin. Do not rinse. Follow with moisturiser. Use 1 to 2 times per week.

About the Brand

COSRX is a Korean skincare brand built on a simple idea, that skincare should be about the ingredients that work and nothing that does not. Its cult formulas, from Advanced Snail 96 Mucin to the Master Patch, pair high performance actives with pared back, barrier friendly formulations, which is why they have become worldwide favourites. Straightforward, effective and gentle on skin. Shop the full COSRX range at SkinShop.ie, Ireland's home for expert skincare.
