COSRX's Alpha-Arbutin 2 Discoloration Care Serum is a triple-action K-Beauty brightening serum formulated with Tranexamic Acid 3%, Niacinamide 5% and NAG 2% to visibly reduce post-breakout marks, dark spots and stubborn discoloration — for a clearer, more even and luminous complexion over time.

Description

Three powerhouse brighteners. One targeted serum. Visibly clearer skin.

Introducing COSRX The Alpha-Arbutin 2 Discoloration Care Serum — a clinically inspired K-Beauty serum engineered specifically for those struggling with post-breakout marks and persistent dark spots. With a triple-active brightening complex of Tranexamic Acid 3%, Niacinamide 5% and NAG 2% (N-Acetyl Glucosamine), this serum attacks discoloration from three different pathways simultaneously — making it one of the most comprehensive and effective dark spot serums available.

Tranexamic Acid at 3% is a next-generation brightening ingredient that inhibits the activation of melanocytes — the cells responsible for producing excess pigment — while also calming post-inflammatory redness. It is particularly effective for skin of colour and for PIH (post-inflammatory hyperpigmentation) caused by acne breakouts. Niacinamide 5% interrupts the transfer of melanin to the skin's surface, evens tone and strengthens the skin barrier. NAG 2% supports cell turnover, gently exfoliates at a cellular level and enhances the brightening effect of the other two actives — creating a synergistic formula that fades discoloration faster than any single ingredient could alone.

Lightweight, fast-absorbing and gentle enough for daily use, this serum is the definitive answer to post-acne marks and uneven skin tone on Fanlora.

Why you'll love it:

• Tranexamic Acid 3% — inhibits melanin production and calms post-inflammatory redness and PIH
• Niacinamide 5% — blocks melanin transfer to skin surface for faster tone-evening results
• NAG 2% — promotes cell renewal and amplifies the brightening effect of the full formula
• Triple-action formula — addresses discoloration from three pathways simultaneously
• Targets post-breakout marks — reduces the appearance of acne scars and PIH
• Dark spot care — fades sun spots, age spots and stubborn hyperpigmentation
• Lightweight dropper serum — layers easily into any AM or PM routine
• Gentle enough for daily use — no harsh exfoliation or sensitivity
• K-Beauty formulation — clinically inspired and effective for all skin tones and types

Key ingredients:

• Tranexamic Acid 3% — next-generation melanin inhibitor that reduces PIH, post-acne marks and overall discoloration
• Niacinamide 5% (Vitamin B3) — prevents melanin from reaching the skin's surface, evens tone and strengthens the barrier
• NAG 2% (N-Acetyl Glucosamine) — supports skin cell renewal and enhances the overall brightening and clarity of the formula

How to use:

• Apply 2–3 drops to clean, toned skin morning and/or evening
• Gently press and pat into face focusing on areas of discoloration
• Follow with moisturiser and SPF in the morning — sun protection is essential when treating pigmentation
• Use consistently for 4–8 weeks for best visible results on dark spots and post-acne marks
