TIRTIR Niacinamide 20% Serum

Brighten, smooth and refine your skin with TIRTIR Niacinamide 20% Serum. This Korean high-performance serum is formulated with 20% niacinamide, alpha-arbutin, glutathione, hyaluronic acid and retinol to help reduce the look of dark spots, blemishes, enlarged pores and uneven skin tone.

The formula contains a high concentration of niacinamide, which helps brighten dull-looking skin, visibly improve uneven tone and support a smoother, more refined complexion. Niacinamide also helps balance the look of excess oiliness and minimize the appearance of enlarged pores.

Alpha-arbutin and glutathione support advanced brightening care by helping improve the look of hyperpigmentation, discoloration and dark spots. Together, these ingredients promote a clearer, more luminous and radiant-looking complexion.

The serum also contains retinol, which helps support skin renewal, improve the appearance of fine lines and promote a smoother, firmer-looking skin texture. Zinc PCA helps balance oily or blemish-prone skin while supporting a calmer-looking finish.

A hydrating complex with hyaluronic acid, hydrolyzed hyaluronic acid and sodium hyaluronate helps attract and retain moisture, leaving the skin feeling plump, fresh and comfortable. Glycerin, butylene glycol and propanediol provide additional lightweight hydration.

The formula is enriched with macadamia seed oil, hydrogenated lecithin, cholesterol and plant sterols to help support the skin barrier and maintain a soft, smooth feel. The lightweight texture absorbs quickly and layers well with moisturizer and sunscreen.
