Scars can be divided into hypertrophic scars and concave scars, as well as ordinary scars (flat). If it's a hypertrophic scar, I suggest you go to a beauty salon or the beauty department of a hospital, but many beauty salons don't go to hypertrophic scars, so you should walk more if you go to a beauty salon. If it is a concave scar, don't go to the beauty salon. Hypertrophic scars and sunken scars can't be directly recovered with ointment in the beauty department (plastic surgery department) of the hospital (except for high-grade brand ointment, which is expensive, but not as affordable as going to the hospital), but it can be diluted. As for ordinary scars, you can choose a beauty salon or use ointment.

If you are satisfied, please accept it. Thank you.
