Below is a link summarizing clinical data on the diode laser:
Diode laser clinical data

There are a few new studies by Alster and Eremia on PubMed you can check out, too. I'll add them to hairfacts as I have time.

Hi, thanks for your informative website.
I just received my first treatment for hair removal on my upper lip by a Diode laser (lightsheer). It was done by a doctor who does all the laser stuff himself, and came recommended. I'm fair, with dark hair. When i got home, and the faint redness had gone away quickly, i noticed that the upper edge of my right lip and a little skin on the side of it looks/feels burnt. When he did the treatment, i remember a 'burning' smell when he treated that particular area. (he said that was normal).
Now, is it possible this is a burn that will not go away? Was he careless, and got too close to the lip? Will it heal? ARRG!! The rest looked so good....
Another question: he wants me to come in for several visits with 3-week lags between visits. Is that too short a time?
Thank you SO much for your reply; it's the beginning of memorial day weekend, i don't know who else to ask, and that doctor won't be back until tuesday! Thanks...! [Frown]

Don't worry! The redness will go away. The Lightsheer is a great laser. I have less redness afterwards with it than with the Apogee, which is also a good laser.

I haven't had my beard done but did talk to my practitioner about it. Redness and swelling is more common with facial hair, at least for men. I wanted to get my chest and back finished before I started on any other areas so I didn't have time.

Did the doctor use compression (press down) with the handpiece. I timproves the results and results in less irritation. The compression forces blood out of the vessels momentarily so the hemoglobin doesn't absorb the laser. And it also rotates the base of the follicle closer to the surface so it can be blasted more easily.

3 week intervals may be normal for facial hair. My practitioner says Lumenis is recommending 8-12 week intervals for back and chest hair at least, because of the power levels used on me, which was 45 Joules.

If you don't mind my asking how much did the treatment cost and is it part of a package? Just to compare, my dermatologist charges $200 to do the upper lip. It used to be $100 I believe. They have just had a significant rate increase, but as an existing patient I get 50% off each treatment. Glad I am almost done. My last hour-long treatment was $65. I thought that seemed kind of low. Now the minimum treatment will be $100. It was too good to last I suppose.

I wonder how much one of those Lightsheer ETs (60 Joules) costs.

I may be able to eliminate what little hair is left with electrolysis. I have some white chest hairs that of course would not respond to the laser. I don't have a lot of them, but I feel like I have wires growing out of my chest. I wonder if the laser made them more coarse. It's probably just that I notice them more because almost all of the other hair is gone.

Sounds like your doctor is doing the right thing.

You should be ok, but I would treat the area as if it were a burn (even if it isn't). Put aloe vera gel (not cream or lotion, but pure aloe vera gel with no menthol or "cooling" additives) on it and keep out of the sun this weekend.

If you do have to go outside, even for 15 minutes, use a sunblock. If it's on your lip, I recommend getting a tube of Vaseline intensive care lip balm with SPF 8. I wouldn't use anything with camphor or menthol-- just petroleum jelly with SPF sunblock. The Vaseline is the least irritating out there, because it's pure petroleum jelly.

As RJC said, you should be fine, but definitely contact your doctor when he returns!

Thank you both for your replies...It still looks very 'burnt' on the lip (only one part, nowhere else), and i'm just wondering..what if it IS burnt? Does that mean i have to live with a burnt/scarred lip for the rest of my life? I just feel so uneasy that i can't talk to my doc right now...Any advice or encouragement? Thank you so much!! [Frown]

If it didn't blister or scab over, it's likely you will heal very well. Even if it did, there are things that can be done to minimize any lasting change in appearance.

Discoloration (lightening or darkening) does happen now and then, and it can sometimes take a few months to resolve. However, your doctor can give you a couple of things to help with that.

I can certainly understand your concern, but as long as you treat the area carefully over the weekend and avoid any sun, your doctor should be able to offer some solutions on Tuesday. I'd insist that he sees you then, though. Don't take no for an answer! A couple of days should not mean a missed opportunity to get it all healed.

Hang in there! [Smile]

I doubt that you will have scarring. At the worst you may have a scab but they will heal. Keep the area moist. My practitioner uses Aquaphor and it has always worked very well.

Do you know the fluence level that was used? Next time you can read it on the machine it has a small TV screen and you can read the fluence level. It is in large numbers possibly followed by a J.

The Lightsheer has more potential to scab because it can deliver up to 60 J. The 60 Joule setting is only used on people with very light skin.

It still doesn't sound like something to worry about. It may take a week or more for the redness to totally go away.

Hey, thanks for your kind responses! The lip seems a bit better, but hopefully tomorrow he'll see me. The doc had told me he was going to use the 'highest' level on the Diode, as my fair skin/dark hair would tolerate it....and it did seem to, until he got too close to my actual LIP! The redness isn't there, it just looks burnt, also like i fell and got a scabbed wound (or something--my mom asked me if i'd fallen...). Anyway, i'll let you know what happens! Arrghh, the tough time we women have! Sounds like your laser stuff's going well? Bye for now--

Hi all,
thanks for all your support and advice. It's now thursday, and my lip (which had looked quite burnt a few days ago) has healed terrifically (whew!). I did let them know at the doctor's office, though i didn't end up going in (they weren't in until wednesday), but when i go for my 2nd treatment i'll be sure to tell him what happened--i think it was a bit of carelessness on his part, which is rather scary, but i believe he's good nonetheless. I guess i should have been prepared for hair re-growth, which is showing just as it was before, already, though i would have thought it would come back more slowly....are these the hairs falling out, or just the normal growth cycle of the hair (which i know is why we need several treatments...)? Thanks!! [Big Grin]
