The degree of scar growth is not only related to the type of injury, post-injury treatment and recovery, but also to a large extent related to the physical constitution of the injured person.

I have a scarring constitution. I had a ganglion cyst resection in middle school. The scar hyperplasia after the operation was very obvious, with a typical centipede shape. I didn’t know much about medicine at the time, and my parents were worried that scars would affect the military academy examination, so I used a different type of scar on the market at that time. All the mainstream scar-removing drugs (including MILI Scar Cream and a series of beauty products) have no effect at all.

If your ex-girlfriend has a non-scar physique (the scars on other parts of the body are not higher than the skin level or are not significantly higher or the proliferation is not obvious when healing), you can try to use scar removal drugs and related cosmetic drugs. The representative drug is Scar Spirit (refer to the one above and what I use myself)

If you have a scar constitution, it is recommended not to waste too much money and you can consider plastic surgery as appropriate.

(Of course, there will still be scars, but they will be as small as possible)
