Here’s my laser experience so far to add to the pool of knowledge…
I recently had test patches done at 3 different clinics. I had it done on the upper leg, where I figured the hair was thickest, and the skin quite tender.
Place #1 used a Nd:Yag CoolGlide laser. They started at 30J, 35-25msec. At this level, I felt nothing. The doctor at this clinic said that you didn’t have to feel it for it to be effective. Gradually it was increased to 47J, 25msec. At this level, I could feel it - just a faint zappy sort of pinprick feeling. Immediately afterwards the skin was reddish, and raised like goosebumps. The bumps subsided after about 30mins, and the redness after 60mins.
Place #2 also used a Nd:Yag CoolGlide laser. However here they did the entire patch at 60J, 20msec. This was VERY different! I’m not sure I could go through an entire session on this level, and I tend to have quite a high tolerance for pain. Interestingly, there was no response afterwards in terms of redness or goosebumps.
Place #3 used an IPL (I think it was MultiLux).
They did three different settings - 12.5J, 13.0J, and 13.5J (can someone explain why IPL would be so much lower than laser?)
Pain was somewhere between #1 and #2 - I could feel it, but it was easily withstandable. Again, no immediate side effects.
Pictures after 3 weeks can be found here:
Basically, #2 seems to be by far the most effective - at least initially. It has removed virtually all the hairs in the area.
#1 seems to have slowed the hair growth, and possibly the stubble is a bit lighter/finer than it otherwise would be, but it certainly hasn’t removed the hair.
And once again #3, the IPL, is in the middle. Strangely, the lighter setting almost seems to be more effective than the stronger zaps on this machine.
Hope this helps. Feel free to comment. I’ll update this further down the track.
