BiON Mandelic Serum
Mandelic Acid has antibacterial properties, regulates sebum production to help prevent the recurrence of outbreaks, clears pores, exfoliates, and increases cell turnover. For issues of hyperpigmentation and melasma, mandelic acid breaks up discoloration caused by such things as sun damage, post-inflammatory hyperpigmentation (PIH), and hormones. What makes this serum so special is that every other ingredient amplifies or compliments Mandelic Acid's properties. Azelaic Acid, Niacinamide, and Lactic Acid form a cocktail that reduces inflammation, exfoliates dead skin, increases cell turnover, strengthens collagen to reduce the appearance of fine lines, and improves skin texture and appearance.

This is a great Mandelic serum. It is gentle enough for use twice daily, and it doesn’t it irritate my skin. It is great for my acne-prone skin and keeps my breakouts to a minimum.
