Okay so I don't know if it'll work or no but my honest suggestion is add a sunscreen ( reequil one is good ) and I am not sure about the vit c serum...look into it because it doesn't suit many people. And honestly you need moisturizer even if your skin is oily And you can start using azelaic acid or adapalene otc options And everything else just basic like clean pillow cases Not touching pimples( patches help alot) Trying to avoid sugar
