Yea, I have been doing this treatment for the last six months. My derm told me two times would take care of it..and I told him no way, these are too deep. I did not have major sun damage, just the brown spots.
As far as pain/discomfort goes, the derm controls the voltage/power of the light/laser impulse. When things were not moving along as I wanted to I asked him to *up the voltage* and man, it really hurt!!!!
. I know him personally, and he is such a freak (in every way..a nice freak, though!) that he's all "I'm going to play the rabbit myself and try it out!! So he puts the laser on his arm and gives himself a shot..he's all "You're being such a baby!" about 10 minutes later we were just talking and he says.."Damn, this really burns!" I said, yeah, see, welcome to my world!!!"
So, it all depends on the voltage/power used. You can ask your derm. to give you a low dose at first.
The costs vary. In Switzerland, well, here I pay 100.00 CHF (about 72.00 Us dollars, I'm guessing) each treatment. Insurance does not cover this, so this is out-of-pocket cost that I must pay cash for. When my treatments began, as I said before, I was told I would not need more than about 3 or 4. I have had six (6) and my spots are getting a little better.
But I believe this is the current best treatment for sun spots/brown spots, etc.
If you have any questions, please P.M. me...
Stay Cool and Take Care!! Elisabeth
