Conventional Q-switched technologies use the Kirby-Desai Scale to determine the number of treatments, That scale does not apply to the Picosure as it does not interact with the skin or the colours of the tattoo in the same way. During your consultation, after seeing your tattoo, we will be better able to suggest the number of treatments it will likely take. Picosure has been clinically proven to take tattoos of in half the amount of treatments, and often even faster. In most cases a minimum of three to five treatments will be required, although we have even seen tattoos come off in a single treatment! This is not common but we have seen it several times!
