Hi Ges Shu,
Don't be worried! Tattoo removal typically doesn't cause scarring.
Such complications are rare with appropriate types of lasers, correct laser settings and good post-treatment care.
I strongly encourage meticulous post-treatment care which consists of anti-inflammatory and antibiotic creams to minimise risk of infection/skin changes. I also tell my patients not to scratch their wounds.
I recommend a Picosecond Laser, which is more effective and safer for tattoo removal than a Q-switched nanosecond laser.
For more information on tattoo removal in Singapore (explains the appropriate type of lasers as well as cost of tattoo removals).
Hope that this helps!
Warmest regards,
Dr Justin Boey
