I have a lot of dark spots on my face. I get pimples around my nose, temple, chin and under my ears quite often. There are too many whiteheads and and blackheads on my nose and chin area. I have a combination skin. I've had treatment from dermatologist in the past but the results weren't permanent. Lately i've been breaking out a lot. I don't have any extreme eating habits and i've control over my sugar consumption too. I've tried a bunch of different products like niacinamide serums, peelings solutions, kozel creams, vitamin c facewash etc. Nothing has really worked. I have moderately sensitive skin. What should I do?
