The verdict spread
Across 39 gurus, the overall verdict is 90% “worth it.”
What the gurus are saying
The gurus found red light therapy solid for building collagen and smoothing fine lines. Consistency is key, though: at least three times a week for 10 minutes, with results typically taking 28 days or more. They also saw benefits for sensitivity and inflammation, though anyone with melasma should patch-test first since the light might worsen it.
