Hi, I've been using LHR for my chest and abdomen - have had about 4 treatments with the regular lightsheer diode and now 2 treatments with the lightsheer duet over the course of 14 months- I'm a type 4-5 skin with corse/fine hair

The first four treatments with the regular lightsheer gave me about 5-10 percent reduction with each session. The settings were about 18-20 joules/cm2 at 30ms - kind of low - but we tried 22 once and I got burned (purpura all over my chest - which thankfully is gone) - so decided we decided to go low.

I have had 2 treatments with the lightsheer duet over the past 2 months (last one was a few days ago) - I have to say that the I was really skeptical cause the they used 7 joules and 100ms - and the hair pretty much immediately started growing again - i thought it was a scam and was gonna ask for my money back - but I observed for a while and at the 4 week mark the hair started to fall out - at the 8 week mark there were patches all over my chest and abdomen (we also did my upper arms and shoulders for the first time as well and those were all very patchy) - with the normal lightsheer the hair would stop falling out at 4 weeks and normal growth was present at 8 weeks- seems to me like the lightsheer duet is more effective than the regular lightsheer - based on the results I saw at 8 weeks on my arms/shoulders - my chest is pretty much all patchy at this point and the areas of regrowth are finer - anyways - i'm pretty happy with the results and will likely stop when the regrowth is evened out.

As for the duet - it is wwaaay faster - much less painful (though you still feel a light pinch) - no lubrication is required - you just have to wait longer for the results smile

All of those settings are not going to result in permanent removal. Give it enough time (4-6 months) and I can guarantee you that it will all be back.

If you got burned at 22j 30ms, you need a YAG laser. Diode is not going to give you permanent results at those settings. Also, 7J 100ms is a complete waste of time.

I would start looking for a good Yag laser like GentleYAG or Apogee Elite, or Coolglide, and someone who knows what they're doing.

Btw, what does "coarse/fine" mean?

By fine/corse I meant corse in the middle and fine on the sides, lol... I was contemplating switching lasers - but after reviewing the studies on the lightsheer, I was pretty confident about it - I would usually push the technician to maximize the joulse and pulse width - but even at lower settings (ie 18-20 joules at 30 ms) Hair was popping out like mad - and all the hair would fall out in 2 weeks - so I knew I was getting the response I wanted - the longest I went without LHR was about 3-4 months - and at the end of it there was a definite reduction in hair -

As for the fluence - the spot size on the duet is huge - which I guess necessitates lowering the fluence (which is at a max of 12/cm2). I'm planning on stopping after 2 or 3 more treatments - I can definitely post pics and let you guys know how it goes - as it stands, i've attained a 40-60 percent reduction... looking for 80 percent before I stop...

By the way, the spot size on the duet is 22 x 35 mm which is huge, so of course the joules need to be lower.

The only problem is that the hair needs to heat up enough to be disabled for good. Shedding is good, but it doesn't necessarily mean it was disabled permanently.

My concern is mostly with the 100ms pulse width, not the joules, since the spot size is so large. It needs to be much lower to be effective in my opinion. Maybe they can take your original setting and go down just enough so that you don't get burned.

i just got treated with the duet- and the 'regular' <ahem> module for the smaller, harder-to-reach bits.

with the regular module it hurt like a bitch- as i would expect it to (on my bikini/underarm eg. epilating is incredibly painful).

i have experienced around 40% shedding in two hours! looking good.

on the areas treated with the duet module (the big spot size) i felt almost nothing. a slight shock in the center of the handpiece, most sensation came from the vacuum- and that doesn't hurt. i didn't expect this!

afterwards i felt no discomfort on the areas treated with the suction module, and witness no shedding/burned stubble/raised follicles.

the fact i felt action concentrated in the center of the piece, and from a video i watched about the duet, suggests the tech needs to make a considerable overlap in order to treat the area evenly.

of course i didn't come away with settings: that would be helpful wink i can call. i totally feel like a pain in the behind constantly getting into discussions with the techs when they are usually pushed for time.

Electrolysis, blend: Jan 2010 - June 2011: brows. Great results, very little new growth.

May 2010: bikini & underarms (with duet), 2x, little results.

Feb 2011: bikini line- 4x, 6-8 weeks in between, great results, very little new growth.

June 2011: Legs 3x standard, 1x duet, not great results. strong, patchy regrowth, likely because settings were capped and machine defective.

miss_m, am I correct in inferring this is the first time you've had your bikini area treated? If so, then two things:

1. I had almost all of my shedding in this area by the third day! I thought that was really soon, but if you've already had 40% shedding then I suppose there's something about this area that reacts that way. Pretty cool, I think.

2. Please keep us updated on how this goes for you. I'm getting this area treated too, and I'm curious. smile

You should wait 3 weeks for shedding to complete. Sometimes it doesn't even start until week 1.5.

my settings are as follows (lightsheer duet):


labia/perenium: Fluence 23 Pulse 30, with ET
bikini: Fluence 6.5 Pulse Custom, with Duet
underarms: Fluence 7.2 Pulse Custom, with Duet
toes: Fluence 29 Pulse 30, with ET

how do these sound to you? i went for a touchup but they still missed some large areas which look like they won't shed.

The settings are ok. You may be able to handle higher, but they would have to test. Are they using compression on the LightSheer? It's necessary for results, especially if they're gliding. It sounds like they're missing areas, potentially due to gliding.
