TIRTIR Niacinamide 20% Serum – 30ml

TIRTIR Niacinamide 20% Serum 30ml is a potent brightening and balancing serum formulated with a concentrated 20% niacinamide blend to help reduce excess sebum, refine enlarged pores, and even out uneven skin tone. This fast-absorbing, lightweight serum supports the skin’s barrier, improves texture, and helps fade post-inflammatory hyperpigmentation with consistent use. Ideal for oily, combination, and dull skin types seeking clearer, smoother, and more radiant skin — but suitable for most skin types when introduced gradually and paired with soothing, hydrating products.
