COSRX Alpha-Arbutin Discoloration Hydrogel Face Masks 3-Pack — Niacinamide & Tranexamic Acid, Hydrating Overnight

COSRX The Alpha-Arbutin Discoloration Care Hydrogel Face Mask is a single-use hydrogel sheet that delivers alpha-arbutin, niacinamide, glutathione and tranexamic acid to help improve skin clarity and hydration while you rest.

This travel-ready 3-piece set uses a clear hydrogel base that adheres closely to skin to maximize ingredient contact. The formulation pairs brightening actives like alpha-arbutin and tranexamic acid with skin-supporting ingredients such as niacinamide, low-molecular-weight collagen and glutathione to target uneven tone and support moisture retention. The mask visibly shifts from translucent to fully clear as the hydrogel releases its serum, making it easy to tell when the treatment has delivered its essence.

How does the mask help even out skin tone?

The mask combines multiple brightening and barrier-supporting ingredients to address discoloration and dullness. It focuses on reducing the look of dark spots and harmonizing skin tone over repeated use without abrasive physical exfoliation.

• Alpha-arbutin: targets hyperpigmentation and age spots.
• Tranexamic acid: works with other actives to reduce visible discoloration.
• Niacinamide: refines texture and supports a balanced tone.
• Glutathione and ferulic acid: antioxidant support for scar and tone recovery.

What hydration and anti-aging benefits does it provide?

Besides brightening, the hydrogel mask delivers deep hydration and a mild anti-aging boost by using adenosine and low-molecular-weight collagen that penetrate more easily. The hydrogel matrix locks in moisture so skin feels plumper and smoother after removal.

• 200 Dalton low molecular collagen for improved skin suppleness.
• Adenosine to support surface-level sign-of-aging concerns.
• Hydrogel contact: reduces evaporation, enhancing serum absorption.
• Leaves a dewy finish suitable for overnight wear.

How should I use these masks for best results?

Use the mask on clean skin after toner or a thin serum layer to improve absorption. Wear for 2–3 hours or overnight until the hydrogel becomes fully transparent, then remove and gently pat remaining essence in—no rinsing needed.

• Step 1: Cleanse, then apply toner/serum.
• Step 2: Remove films and apply hydrogel securely to face.
• Step 3: Remove after 2–3 hours or when mask is clear; massage in essence.
• Patch test first and stop use if irritation appears within 24 hours.

Will this mask fit different face shapes and travel well?

The hydrogel construction is flexible and molds to most facial contours, creating close contact for even delivery of actives. Packaged as single-use pouches, the 3-mask set is convenient for trips or targeted skin treatments.

• Stretchable hydrogel conforms to nose, cheek and chin contours.
• Individual sealed pouches prevent spills when packed.
• Transparent finish allows easy wear-time checks.
• Single-use format ideal for trialing or travel routines.

Who is this for: This COSRX hydrogel mask is designed for anyone seeking an intensive, non-abrasive approach to reducing the appearance of uneven tone and improving hydration—suitable for those wanting an overnight treatment, travel-friendly skincare boosts, or occasional brightening sessions. It’s ideal for users already comfortable with active ingredients (alpha-arbutin, niacinamide, tranexamic acid) and who perform a prior patch test to confirm skin compatibility.
