Researchers have reported that a daily capsule containing PQQ, ergothioneine, quercetin, and proanthocyanidins led to improved skin hydration over an eight-week period. The findings, published in the journal Cosmetics, involve a modest group of participants who saw measurable increases in moisture levels.
Why it matters
Understanding how oral supplements might influence skin health is a growing area of interest for consumers, as companies increasingly look to validate their specific formulas through clinical testing. This study provides preliminary data on how a particular blend of ingredients performs when measured by professional skin imaging tools.
In an open-label, single-arm exploratory study published in Cosmetics, 31 women aged 36 to 56 showed an average skin hydration increase of 58.6% after 56 days of daily supplementation. These results, which compared final cheek hydration readings of 70.3 to an initial 44.3, are preliminary.
The players
Centre Testing International Pinbiao
A research organization based in Shanghai that conducted the clinical investigation.
Cosmetics
A peer-reviewed scientific journal that publishes research on the efficacy and safety of skincare and cosmetic products.
The details
The study tracked changes in skin surface moisture using a Corneometer CM 825 and PRIMOS CR 3D imaging. Participants took one BeautyU capsule daily, which contains a blend of PQQ, ergothioneine, quercetin, and proanthocyanidins. Researchers monitored these subjects over the 56-day period to evaluate the impact of these specific compounds on epidermal water content.
Timeline

Health Landscape
The study was officially registered on ClinicalTrials.gov, aligning with broader scientific efforts to standardize the testing of cosmetic supplements. This approach follows the trend of moving toward objective, instrument-based verification for ingestible skin health products.
These findings are preliminary and should not be interpreted as a replacement for standard dermatological care or established skin health practices. If you are considering adding supplements to your routine, discuss the ingredients with your doctor to ensure they do not interfere with other treatments.
The takeaway
While this study observed an increase in hydration using a specific capsule, it is important to remember that such findings are limited by the small, short-term nature of the trial. Always verify the ingredients of any supplement with your primary care physician before adding them to your diet.
