The product
The TIRTIR Niacinamide 20% Serum is your ultimate go-to for radiant, healthy-looking skin. This powerful serum contains a high concentration of niacinamide, also known as vitamin B3, which is known for its versatile benefits. With a formula that contains up to 20% niacinamide, this serum helps to brighten dull skin, refine pores, and improve the overall texture of your skin.
The lightweight, fast-absorbing formula ensures that the active ingredients penetrate deep into the skin, giving you an instant refreshing boost. Niacinamide is known to regulate sebum production, meaning it’s perfect for both dry and oily skin types. It also helps to reduce redness and fade hyperpigmentation, leaving your skin looking more even and refreshed.
