Summary

This study tested whether taking oral collagen supplements can increase collagen in the skin of people who had weight-loss or tummy-tuck surgery. 102 participants received either collagen peptides or a placebo for several weeks. Researchers then compared skin biopsies and scar quality to see if the supplement made a difference.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: bovine collagen peptides
What this could lead to: If it works, this could point toward a simple supplement to improve skin healing and scar quality after surgery.
What could go wrong: This is a small, completed trial with no phase designation, so results may not be conclusive. Collagen supplements are not regulated like drugs and may not work for everyone.
