Gentlelase is a type of alexandrite laser. Gentlemax is both an alexandrite and YAG laser in one. I don’t know enough about lightsheer to give a good judgement, but I think I remember reading it’s more difficult to use.
Personally, I like the gentlelase/gentlemax more than the apogee series, but that’s just me.
I’ve had 4 sessions so far and I notice quite a reduction already. If your laser sessions use very high and powerful settings, it shouldn’t take 10 sessions, but it also may cost more than $200-250 as well. You should find different centers with a laser (Candela’s website has a practitioner locator for people who own their lasers).
Lastly, it will hurt like hell (if not, then it’s not being effective.) My dermatologist gives me numbing injections in my face to help the pain, and it can still hurt a lot. In addition, what she does on me… she goes over my face and neck with the alexandrite laser and then goes over it again with the YAG portion (she has a GentleMAX). If you can find someone with a gentlemax, you may be able to ask if they can do that on you. I have found that to be quite effective.
