If you've been following skincare recently, you'll know that every influencer and skincare enthusiast loves niacinamide (Vita B3). This ingredient is good for all skin types and serves many purposes, such as brightening, firming, acne-fighting, sebum control, etc. If you have oily skin, you're going to love this. The little bumps and whiteheads I get between my brows and in my cheek pores disappear with long-term use of this product and other niacinamide products. However, this one from TIAM is different because of the 2% arbutin. Usually you'll see 2% zinc in other niacinamide serums. Arbutin, has proven to be way more effective and potent than niacinamide, in terms of brightening. I believe everyone should have a product like this in their skincare routine. Plus, it's 40ml.
