What Did the Study Show? (In Simple Terms)
The clinical trial evaluated 46 women aged 45–59, supplementing them with hydrolysed marine collagen for 90 days.
Using high-resolution imaging, ultrasound, and confocal microscopy, researchers measured changes to wrinkles, skin density, dermis thickness, collagen structure, and visible skin texture.
Key results after just 90 days:
✔ Significant reduction in wrinkles
Frontal, nasolabial and periorbital wrinkles all improved — some by 31% — compared to the placebo.
✔ Improved dermal collagen density
Ultrasound imaging showed increased dermis echogenicity, a marker of collagen-rich, firm skin.
✔ Thicker, more hydrated dermis
Participants showed a measurable increase in dermis thickness, suggesting better hydration and structural support.
✔ Healthier collagen architecture
Confocal imaging revealed:
- 100% reduction in huddled (damaged) collagen
- 19% reduction in elastosis
- 20% increase in coarse, youthful collagen fibres
✔ Reduced pore appearance
High-definition imaging showed a decrease in both fine and large pores.
✔ Visible improvements noticed by participants
Most women reported better:
- Firmness
- Tone
- Hydration
- Smoothness
- Wrinkle reduction
In short: this study demonstrated that marine collagen peptides can improve multiple markers of skin aging — even at a low daily dose.
