Personally, I felt very impulsive when I was a child, and it was difficult to wash it off later.
Suggestion: It is best to find a professional place to wash tattoos, and it is required to remove them through the epidermis with a laser that does not hurt the dermis. Shallow tattoos can be done once, and deeper tattoos will probably be repeated many times, with a long interval, because skin recovery takes a cycle. If washed well, it will generally not leave any traces.
As far as Chengdu is concerned, several large beauty salons and hospitals have such conditions, but the most expensive square centimeter of Huamei is 5000- 10000, so it is not recommended to go.
You can find a professional tattoo cleaner first, otherwise the hospital price will be lower. Never grind or pickle yourself, and don't use old-fashioned laser to leave scars that can't be cleaned.
