Talk to Dermatologist on Acne And Dark Spots Issue

Hi, i am a 22 year old and i acne issues since 2023 now i have control the production of pimples through diet, workout, and skin care but my the spots after pimples are not vanishing those spots make my skin look dull and feel like that i have pimples. Currently I'm using azelaic acid serum, niacinamide serum, and centella asiatic serum for my skin through this my pimples production is very controlled but near my periods i have few breakouts which makes my skin again ugly because when new pimple form the redness of that pimple and then after spot makes the skin look dull. I want you to suggest me a skin care that targets my black spots and make my skin fresh and glowy and if a new pimple is forming suggest me a cream that will kill the pimple bacteria and remove the pimple and it's spot(means stop the pimple growth). In daylight I'm using mask should i continue to use the masks or not in my skin condition?
