LED treatments are one of those things that have been approved not because they were effective, but because they didn't harm anyone. The FDA approves certain things based on evidence that they are safe, but not necessarily effective.
Most dermatologists realize this and have steered clear of these treatments, knowing that they are basically a sham. On the other hand, the promoters of these have sold them widely to medispas and other physicians who really don't know all that much about the science but are looking for something to 'upsell' patients on and don't really care if they work or not.
The other sad comment is that if the Fraxel re:pair worked on acne scars as the folks who promote it for this say it does, you wouldn't need to do anything other than sit back and relax after the treatment. Unfortunately, as I have stated on many other posts on Real Self, the Fraxel re:pair's results for acne scars are way overstated. For wrinkles, the re:pair is excellent, but for acne scars, not so much...
The take home message on this is that for acne scars, the treatments aren't all that great whatever you do and I wouldn't even think of wasting another dollar on LED as that is the poster child for bogus treatments whose only aim is to enrich the clinic or physician who is telling you to have it!
