A new study published in Frontiers in Nutrition suggests that a combination of collagen peptides, antioxidants, and hyaluronic acid may help improve signs of facial skin ageing. Researchers say the results show potential benefits, but stress that the findings apply to the combination of ingredients rather than any single component.
Study overview
The research tested a mix of three ingredients: collagen peptides (CP), ergothioneine (EGT), and sodium hyaluronate (NaHA). Scientists used both laboratory skin models and a small clinical study involving 32 women aged between 30 and 55 in China.
Participants took daily supplements for eight weeks. Their skin was assessed using imaging tools and measurements of hydration, elasticity, and barrier function.
Key results
The study reported improvements in several areas of skin health. These included better hydration, increased elasticity, and reduced water loss from the skin. Researchers also observed a reduction in wrinkles, including crow’s feet and facial lines.
In laboratory tests, the combination appeared to protect skin structure from UV damage. It also showed signs of reducing inflammation and supporting collagen levels.
How the combination works
Researchers say the three ingredients target different aspects of skin ageing. Collagen peptides may support skin structure, sodium hyaluronate helps with hydration, and ergothioneine acts as an antioxidant.
Together, they may address multiple causes of ageing, such as oxidative stress, inflammation, and breakdown of skin tissue.
Limitations
The study has several limitations. The clinical trial was small and did not include a placebo group. It also focused only on women within a specific age range.
Experts say larger and longer studies are needed to confirm the results and understand long-term effects.
What it means
The findings suggest that combining multiple ingredients could be more effective than using a single supplement. However, the study does not prove that collagen alone is responsible for the benefits.
Researchers advise that people should consult a healthcare professional before starting new supplements, especially if they have existing health conditions.
Further research is expected to explore how such combinations compare with other treatments for skin ageing.
