What it is: A highly concentrated vitamin B3 serum that effectively tightens and minimizes the look of sagging pores and rough bumps.

What it does: This innovative serum is the first to contain niacinamide (or vitamin B3) at a safe, effective 20% concentration. Niacinamide is a smart, multifaceted ingredient that uniquely penetrates skin's surface to help improve the look of sagging, stretched pores. It normalizes pore function and protects from further stretching when exposed to UV light for a dramatically smoother, younger-looking complexion. This advanced concentration is complemented by purslane and acetyle glucosamine to help steadily smooth rough, orange-peel texture and tenacious bumps.

How to use: Apply a few drops once or twice daily after cleansing, toning and exfoliating skin. At night, layer with other treatment products as needed and follow with your moisturizer. During the day, finish with broad-spectrum protection.
