​Hi. ​ Acne treatment has multiple stages - to control new breakouts, to clear the sequalae (pigmentation and scars) and to prevent a relaps​e. ​ Dark circles around the eyes at your age is unusual and could indicate an insulin resistance. Skin is the mirror of internal health and to get a perfect skin you need to treat both ways - internally and externally. ​Now-a-days many chemical peels also offers realistic promise- like glycolic acid and lactic acid peels. Dermapen in combination with mesotherapy  also helps. ​ You may need oral medications. ​
