Common Questions

How does TIRTIR Niacinamide 20% Serum reduce dark spots?
The maximum-strength 20% niacinamide concentration works alongside alpha-arbutin and glutathione to interrupt melanin production and speed up fading of stubborn hyperpigmentation.

Can this serum be used on sensitive skin?
Due to the high 20% niacinamide concentration and retinol micro-dose, perform a patch test first or introduce it gradually into your routine if you have sensitive skin.

Does this serum leave a sticky residue on the skin?
No, the weightless fluid texture absorbs rapidly into the skin, leaving a fresh, smooth, and comfortable finish ready for layering.

Should I wear sunscreen while using this serum?
Yes, because the formula contains retinol to accelerate skin turnover, always apply a broad-spectrum sunscreen during the day to protect your results.

How often should I apply TIRTIR Niacinamide 20% Serum?
Apply once or twice daily after cleansing and toning, depending on your skin's tolerance to high-potency active ingredients.

Why You Will Love TIRTIR Niacinamide 20% Serum

The TIRTIR Niacinamide 20% Serum offers an advanced, high-performance solution for those battling persistent hyperpigmentation, uneven skin tone, or texture irregularities. It works by combining a maximum-strength 20% concentration of niacinamide with alpha-arbutin and glutathione to block melanin synthesis and fade stubborn dark spots. The formula uses zinc PCA and multi-weight hyaluronic acids to flood the skin with moisture while balancing surface oil production throughout the day. A micro-dose of retinol accelerates cellular turnover to smooth fine lines and refine coarse pores for a glass-like finish.
