Brand new in box, never opened. “A highly concentrated niacinamide (vitamin B3) serum that effectively tightens and minimizes the look of enlarged pores and bumps caused by age or sun damage. This innovative serum is the first ever to contain niacinamide at a safe, effective 20% concentration. This advanced level, complemented by purslane and acetyl glucosamine, steadily smooths out rough, orange-peel texture and tenacious bumps. Niacinamide (vitamin B3) is a smart, multifaceted ingredient that uniquely penetrates skin’s surface to help improve the look of enlarged, stretched pores. It normalizes pore function and protects from further stretching when exposed to damaging UV light for a dramatically smoother, younger-looking complexion.” - Dramatically reduces the look of enlarged pores - Helps reduce hard, clogged bumps & orange-peel texture - Visibly improves blotchy tone & fades post-blemish marks 0.67 oz / 20 ml
