Hello, yes tattoo can be removed or significantly lightened using Qswitched ND yag LASER. It is a simple and painless procedure. Cost will depend upon size of the tattoo. Number of sittings required usually can be estimated after having a look at the tattoo first, as it depends upon color and depth of tattoo. For example unprofessional tattoos tend to be deeper, so they require more number of sittings. Approximately 5 to6 sittings may be required. Cost for a tattoo of 10 by 10 cm may go up to 5000 per sitting approximately. Regards, Dr.Shruti Jadhav Devershi, Sólskin Professional Dermacare, Kharadi, Pune.
