light-emitting diode therapy LEDT red light therapy wound healing ecchymosis edema

Studysummary This randomized controlled trial reported that light-emitting diode therapy significantly reduced ecchymosis and edema and accelerated wound healing in patients during the first two weeks following rhinoplasty, without any adverse effects. Our plain-language summary of this paper — not a Tressless recommendation.

A randomized controlled clinical study involving 60 rhinoplasty patients evaluated the effects of light-emitting diode therapy (LEDT) on postoperative complications. The intervention group received red light therapy (660nm) three times daily for 10 minutes over 14 days. Results showed a significant reduction in ecchymosis and edema in the intervention group compared to the control group, with ecchymosis improving significantly in the first two weeks and edema primarily in the second week. Wound healing was notably better in the intervention group at two weeks and one month post-surgery. No adverse effects were reported, suggesting LEDT is effective in reducing early postoperative complications and accelerating recovery after rhinoplasty.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.
