Key Ingredients

2% Alpha-Arbutin, a stable, water-soluble brightening ingredient, helps regulate excess melanin to improve dark spots, sun spots, and post-acne pigmentation. Tranexamic Acid (TXA) works alongside it to address stubborn discoloration and PIH, while Niacinamide brightens dullness, refines pores, and strengthens the barrier. N-Acetylglucosamine (NAG) complements both by supporting renewal and smoother, more even-looking texture.

Ferulic Acid and Glutathione provide antioxidant protection, while Hyaluronic Acid, Sodium Hyaluronate, Panthenol, Madecassoside, Allantoin, Licorice Root Extract, and Glycerin hydrate, soothe, and reinforce the moisture barrier.

Note: Ingredient lists may be updated by the manufacturer — always check packaging for current INCI details.

Product Specifications

Skin Type Suitability

Suits normal skin for daily brightening maintenance, oily and combination skin thanks to its lightweight, fast-absorbing feel, and dry skin via Hyaluronic Acid and Panthenol. Madecassoside, Allantoin, and Licorice Root Extract make it comfortable for sensitive skin, while it helps fade marks on acne-prone skin without heavy oils. Not intended to treat medical pigmentation like melasma; those with allergies, broken/infected skin, or who are pregnant/breastfeeding should consult a professional.

How To Use

After cleansing and toner, apply 2–3 pumps or drops and pat gently over the face and neck until absorbed, then follow with moisturizer. Suitable for daily morning and evening use; always finish daytime routines with broad-spectrum sunscreen (SPF 30+), since UV exposure can trigger new discoloration.

Authenticity

COSRX is a globally recognized Korean skincare brand known for evidence-backed, ingredient-focused formulations rather than exaggerated claims. To ensure authenticity, buy from an authorized retailer specializing in genuine Korean skincare, and check for the official COSRX logo, batch number, and expiry date.
