Thanks for the query.
Tattoo removal is multi-session treatment and usually can last for a year or so. If there is no contraindications you can start the treatments. Usually it's safe and painless.. there are various types of tattoo removal machineries available and based on your tattoo type, the Dermatologist will recommend a suitable one. It also depends on the colour of tattoo and if it was done by a Professional tattoo maker or someone novice.
Revlite I.e. Q Switched Nd YAG laser is most commonly used and recommended.
Hope it helps
