Anal darkness and dark spots

Stephanie

So I noticed that I have had anal darkness and it’s honestly not very pleasant since I get very insecure about it when going to the beach. I also have other dark spots on my armpits and because of my body acne. I really want to get rid of it though but I want to know if there is any treatment (preferably pills) that is very effective to get rid of it so pleaseee let me know!!!
