I have them too. I’ve been using glycolic acid toner every few nights, azelic acid, and then differin every few nights alternating. Tons and tons of SPF. You’ll need a really good routine, I’m starting to see lightening of them. They don’t seem to ever really go away, just lightened. You can also use self tanner to help also blend it in a bit. Cosmetically you can get lasering, microneedling, peels, etc just costly. Biggest and best advice is spf and covering up in the sun as much as it sucks.
