@medicines.expert2: Niacinamide; "Oily skin? Acne marks? Large pores? One ingredient can target all three—Niacinamide, also known as Vitamin B3. It controls oil, strengthens the skin barrier, reduces redness, and helps fade acne marks. That's why it's one of the most recommended skincare ingredients by dermatologists." #oilyskin #acne #beauty #niacinamide #viralvideo
