COSRX The Alpha-Arbutin Discoloration Care Hydrogel Mask 3 Sheets

WHY WE CHOSE THIS

We tested 8 brightening masks. Most were too acidic or left skin sensitized. COSRX's Alpha-Arbutin formula is the only one that visibly faded our tester's post-acne dark spots after 4 uses without any irritation. From COSRX — the clinical K-Beauty brand trusted for ingredient-first formulas.

WHO IT'S FOR

• Post-acne dark spots and hyperpigmentation that won't fade
• Uneven skin tone and sun damage
• Anyone who tried brightening products and ended up with irritation instead of results

THE TEXTURE

A smooth, cooling hydrogel that adheres evenly and delivers a concentrated dose of brightening actives. Removes cleanly. No sticky residue. Skin looks more even-toned immediately after.

HOW TO USE

After cleansing and toning, apply mask to face. Leave 20–30 minutes. Remove and gently pat in remaining essence. Follow with moisturizer and SPF. Use 1–2x per week.

THE FULL INGREDIENT STORY

• Alpha-Arbutin 2% (targeted dark spot fading without irritation)
• Niacinamide (overall brightening + pore minimizing)
• Hyaluronic Acid (hydration + plumping)
• No fragrance. No alcohol. No parabens.
