USANA Health Sciences (NYSE: USNA) has released results from a 12-week consumer study on its Glow skincare supplement. The trial showed strong self-reported improvements in skin appearance among participants.
The study included 36 participants — 22 from the United States and 14 from Mexico. Participants tracked changes in their skin over 12 weeks.
Results showed consistently high levels of reported improvement:
These percentages were consistent across both the U.S. and Mexico groups.
Many participants shared positive personal experiences.
One noted that their skin looked healthier, more vibrant, and more youthful, with others noticing the change. Another said they received frequent compliments and felt more confident. A third reported that fine lines and wrinkles appeared reduced while skin felt more elastic and looked brighter.
Glow is designed to support healthy, radiant-looking skin from within. Its formula includes Damasty® (rose extract, bioactive melon superoxide dismutase, and acerola cherry vitamin C), plus astaxanthin and grape seed oil.
These ingredients aim to support skin radiance, hydration, even tone, collagen production, and the body’s natural defenses against environmental stressors.
Brent Neidig, Chief Commercial Officer at USANA, said the results reflect the company’s belief that radiant skin starts from within. Dr. Kathryn Armstrong, Chief Scientific Officer, added that the trial confirmed what the ingredient science was designed to deliver — visible improvements in brightness, evenness, and hydration over 12 weeks.
