If they are small you can try caring for them so that they continue to heal as best as possible :)
There are scar-gels with rollers, like the one from 'bepanthen' (I personally really liked just the feeling of it, haha) or just rollers for scars in general. They are called 'Derma rollers' and work by micro needling your skin. They break down the skin tissue and leave micro wounds in your skin that help the skin
,,This type of rolling stimulates the production of collagen and elastin, breaks down scar tissue, and enhances the absorption of topically-applied nutrients.''
Other stuff is onion extract, aloe vera, honey, plant oils, vitamin E and Vitamin C.
I am not saying that medical procedures are a bad idea, since I have looked into those too when I was younger but this is just stuff you might want to try first and maybe it will a lot :)
Wish you the best!
