Glycolic acid is the smallest of the alpha hydroxyl acids, and holds an abundance of benefits. From loosening dead and hydrated cells, increasing the rate of exfoliation to improve skin texture and tone, and fostering a natural glow, it's no wonder why it is so effective in curating the best night serum.

Glycolic Brightening Renew Overnight is clinically tested effective, with measurable improvements in key markers of facial glow:

18% improvement in radiance
21% improvement in skin texture
10% improvement in skin tone

Protocol: An 8-week, single-center, clinical study was conducted on 50 females, ages 25-64, with global fine lines, uneven skin tone, rough skin texture, and a dull complexion. Glycolic Brightening Renew Overnight was used once nightly in conjunction with a sunscreen.
