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
