Summary

This study tested two treatments made from patients' own blood—platelet-rich fibrin and platelet-rich plasma—with or without microneedling, to see which works better for stretch marks. Thirty adults received different treatments on each side of their body over five sessions. Researchers measured changes in stretch mark severity and patient satisfaction.

What this could mean

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

Active substance
Platelet-rich fibrin and platelet-rich plasma (both derived from the patient's own blood)
What this could lead to
If successful, this could point toward a more effective, natural treatment for reducing the appearance of stretch marks.
What could go wrong
This is a small, completed study with only 30 participants, so results may not apply to everyone. The treatments are cosmetic and may not work for all types of stretch marks.
