Hey, I haven’t used any yet myself but have heard good things about a ‘prosil’ stick which you can get on amazon, as well as aloe vera gel.
Some people use silicon scar sheets too!
Hopefully you find some thing that works for you, I heard they naturally go quite lightbfirst of all and then turn red, so don’t be alarmed if they seem to get worse after they got better. I think they gradually then go lighter again 🙂
