Please read the links. FAQs has prices ranges in addition to other useful info. These treatments aren’t cheap and it’s easy to waste your money, so I would really strongly advise you not to skimp on doing the right research (at least by reading the information in our FAQs thoroughly - I wrote it, so everything I would type again here is already in there).
Ideal Image has good machines, but they’re definitely on average more expensive than other clinics. You really need to use Candela’s search feature and then visit clinics for free consultations to get a feel for whether they are honest and know what they’re doing. And in order to judge this, you need to know the correct answers yourself, which the FAQs will help with.
