Are there any clinical studies supporting the skin benefits of maqui berries?
Yes, there are clinical studies supporting the skin benefits of maqui berries:
A randomized double-blind placebo-controlled pilot study examined the effects of Delphinol®, a standardized maqui berry extract, on skin health in Japanese women. The study found:
- Increased skin brightness: Skin saturation significantly increased after 8 weeks of Delphinol® intake.
- Reduced facial redness: Reddish spots significantly decreased after 4 weeks of intake.
- Improved collagen content: The collagen score, which typically decreases with age, slightly increased after 8 weeks of Delphinol® ingestion.
The researchers concluded that daily oral intake of maqui berry extract can help maintain healthy facial skin condition.
Another preliminary study investigated the photoprotective properties of maqui berry extracts on human skin fibroblasts exposed to UVB radiation. The results showed:
- Maqui extracts did not cause cytotoxicity in skin fibroblasts.
- When fibroblasts were exposed to UVB radiation in the presence of maqui extracts, their viability was increased or maintained.
- Maqui berry extracts demonstrated a slight protective effect against UVB-induced skin damage.
While these studies show promising results for maqui berries’ skin benefits, it’s important to note that more research is needed to fully establish their efficacy and optimal use for skin health.
