Oral Collagen: Proven Efficacy on Wrinkles in 6 Weeks
2 min read

A study published in MDPI Cosmetics in 2024 provides solid clinical evidence on the effectiveness of oral collagen peptides.
STUDY DESIGN
- Type: randomized, double-blind, placebo-controlled trial
- Duration: 6 weeks
- Substance tested: low molecular weight collagen peptides
- Parameters measured: facial wrinkles, skin hydration
RESULTS
Participants in the collagen group showed:
- Significant reduction in facial wrinkles
- Measurable improvement in skin hydration
- Visible effects from 6 weeks of supplementation
WHY MOLECULAR WEIGHT MATTERS
Low molecular weight collagen peptides (<3000 Da) are better absorbed by the intestine and more effectively reach the deep layers of the skin.
MARKET CONTEXT
Collagen supplements represent a rapidly expanding market. They are available as:
- Powder to dilute
- Beauty drinks
- Capsules and tablets
With age, collagen levels drop drastically: at 70, they represent only 40% of initial levels. This decline explains the growing interest in supplementation.
LIMITATIONS TO NOTE
Not all products are equal. Quality, source (marine, bovine, porcine) and molecular weight directly influence effectiveness.
