Tirtir Niacinamide 20% Serum - 30ml

Tirtir Niacinamide 20% Serum is a high-potency brightening serum with 20% niacinamide, one of the highest concentrations available in K-beauty, combined with alpha-arbutin, glutathione, retinol, zinc PCA, and 3 types of hyaluronic acid. This powerhouse formula targets blemishes, hyperpigmentation, enlarged pores, and uneven tone simultaneously.

Alpha-arbutin and glutathione work alongside the 20% niacinamide to create a triple-brightening system that fades acne scars and dark spots while promoting even skin tone. Retinol boosts cell turnover for anti-aging benefits. Zinc PCA balances oil production. Three forms of hyaluronic acid, hyaluronic acid, hydrolyzed hyaluronic acid, and sodium hyaluronate, provide multi-depth hydration. Dermatologically tested and gentle enough for sensitive skin.

Pro tip: 20% niacinamide is significantly higher than most products on the market (typically 5-10%). If you're new to niacinamide, start with once daily and build up, some people experience mild flushing at high concentrations. The combination of alpha-arbutin + glutathione + niacinamide is a serious brightening triple-threat, you should see visible fading of dark spots within 4-6 weeks of consistent use. The added retinol makes this a multi-tasking serum, but avoid layering with other retinol products. Dermatologically tested, so it's surprisingly gentle despite the high actives concentration.
