How to get clear skin

M

Does anyone know what I can do / use to get clear skin?? I used to have kinda bad acne problems but not severe as a teen and now (20yrs almost 21) I get occasional breakouts. I have a lot of acne scars and they are red and I also have red skin even though I don’t have acne scars there (like around the edges of my nose) I also have pretty dark under eyes and my forehead used to be fine (hardly any acne) but now there are small bumps (barely noticeable from afar) and my forehead is very dry. My skin is overall really bad. I got a huge pimple on my nose and I’m noticing how bad my skin is getting. Does anyone know of products that will help me get clear skin? I drink tons of water and don’t eat as unhealthy. I just want to stop wearing makeup but my skin is so ugly with all the redness and scaring that I don’t feel comfortable leaving the house without makeup. Please help 😢
