Tirtir Niacinamide 20% Serum 30ml
Transform dull, uneven skin with the Tirtir Niacinamide 20% Serum, a high-performance Korean brightening serum formulated with a powerful 20% concentration of Niacinamide to visibly improve skin tone, minimise the appearance of pores and strengthen the skin's natural barrier. This lightweight, fast-absorbing serum helps reveal a smoother, clearer and more radiant complexion while delivering lasting hydration.
Designed to target dark spots, post-acne marks and uneven skin texture, this concentrated formula works to regulate excess oil production while refining pores for a healthier-looking complexion. Its silky texture absorbs quickly without feeling sticky, making it suitable for both morning and evening skincare routines.
Enriched with hydrating and soothing ingredients, the serum helps maintain the skin's moisture balance while reducing redness and supporting barrier repair. With continued use, skin appears brighter, firmer and noticeably more even-toned.
Ideal for anyone looking to fade pigmentation, improve skin clarity or achieve a radiant glass-skin glow, the Tirtir Niacinamide 20% Serum delivers professional-level results in a gentle daily formula.
