This is a great niacinamide+arbutin serum, and it's affordable too. I really appreciate that TIAM updated the packaging and this serum now comes in a completely opaque glass bottle (unlike other niacinamide serums), so there's no worry of light degrading the product. The serum is fragrance-free and feels slightly slippery but it absorbs well, is non-sticky and pairs well with other toners and essences.
