I have spots from sun damage (stupid in my youth), damage from rosecea, light scarring (chicken pox & pre-cancer removed) and changes to my skin just because of age. Overall damage covered my entire face. I am in my 50's and have only wore sunscreen daily for the last 12 years or so; plus started wearing a hat when I'm outside working.
The doctor explained everything of what to expect during the consultation and before the procedure. The only thing she didn't mention was the pain. It was more of shock reaction on the first on, after that I knew what to expect and had no problem. My face was hot and slightly swollen for a few short hours. They gave me an ice pack to use until I got home; only needed it for a few minutes after the numbing started wearing off. The total procedure took about 30 minutes (including the numbing process).
Some of the worse spots started during dark immediately. Others by the next morning. Others not so much. For me it took 5 days before they started flaking off and took a full 2 weeks to completely come off. I followed the doctor's instructions not to scrub or pick at them. She also told me to make note of how dark, how long and anything else associated with the treatment so they could adjust treatment accordingly.
So far I am impressed with the results. Dramatic? No, but I notice the difference. I was told I would probably need 3 treatments. I go in 2 weeks for my second one. I'll post pictures after the last treatment has healed.
After all the reviews I have read (not just here), it changed my mind about having the treatment done at a spa. I had my dermatologist give me a referral. Insurance does not cover the cost. The surprise to me - the cost was the same as the spa and it's the doctor not a technician doing the treatment. Made me feel a lot more secure in having the laser treatment done.
A note about cost. From how I understand, the cost can differ between patients depending upon the needs of the individual.
