I'm curious about removing dark spots and blemishes.

Lately, I've noticed more dark spots and blemishes. I'm wondering if they can be managed with dermatological treatments, and if so, which treatments I should consider. Also, I'm curious about at-home skincare routines or precautions I should take. Avoiding sunlight would probably be the best, right?

Would a massage help with that instead?

I'm curious about what would be good to do.
