NUMBUZIN No.5 Vitamin Concentrated Serum is designed to help fade the look of dark spots and hyperpigmentation while improving overall tone for a clearer, more luminous-looking complexion. With a gentle, daily-use brightening blend, it suits oily, dry, combination, acne-prone, and sensitive skin types.

Glutathione for Dark Spot & Dullness Care
Formulated with glutathione, a well-known antioxidant in Korean skincare routines, this serum helps improve the look of dull, uneven tone and spot-like discolouration. NUMBUZIN No.5 Vitamin Concentrated Serum supports a clearer-looking finish by helping reduce the appearance of melanin-related dullness and unevenness over time—without relying on harsh-feeling actives.

Vitamin C + Niacinamide + Tranexamic Acid for Tone-Evening Support
Powered by vitamin C, niacinamide, and tranexamic acid, the formula is designed to target uneven tone from multiple angles—helping brighten the look of pigmentation, acne marks, and tired-looking skin. NUMBUZIN No.5 Vitamin Concentrated Serum is positioned as a “daily dark spots serum” that fits easily into both morning and night routines.

Barrier-Comfort Hydration + Clinically Tested Results
Balanced with panthenol and ceramides for soothing hydration support, the serum is designed to stay comfortable on sensitive or blemish-prone skin. In clinical testing, it was reported to even skin tone by 18.90% and reduce dark spots by 9.65% in 4 weeks, and it has completed hypoallergenic and skin irritation testing (individual results may vary).
