Netizen: Kang Hua Plastic Surgery Network: Laser tattoos can't be washed off once. It takes at least two or three times to lighten the color, but it can't be thoroughly washed like the skin before tattoo. And the process is long (it takes six months to a year to complete the whole course of treatment), so fashionistas should think twice before tattooing. Although tattoos are not very expensive, they will also suffer some crimes. At present, laser tattoo removal projects have been set up in general 3A hospitals or professional plastic surgery institutions. Be careful not to go to beauty salons and other non-professional institutions to wash tattoos, because it is cheap. If it is not clean, it will be more beautiful to leave a scar.
