Product description

A concentrated vitamin C serum that brightens dull skin, reduces dark spots and boosts overall radiance.

COSRX The Vitamin C 23 Serum is a high-strength brightening treatment designed to visibly improve skin tone and texture. With 23% pure vitamin C, this serum helps target hyperpigmentation, dark spots and post-blemish marks while promoting a more luminous, even complexion. Its antioxidant-rich formula also helps defend the skin against environmental damage, supporting a healthier and more youthful appearance.

The lightweight, silky texture absorbs quickly, making it suitable for both morning and evening routines when paired with SPF during the day. Ideal for dull, uneven or pigmentation-prone skin, this serum promotes smoother, brighter and revitalised skin with consistent use. Sensitive users may prefer to introduce it gradually due to its potency.
