Treating the problem should be your main focus. Putting makeup on the affected areas is not going to help and may even worsen the problem. Have you tried getting professional help from a dermatologist? It may be that the particular kind of acne you have doesn't seem to be responding to topical treatments because it's the result of hormonal issues, in which case you might need to go on medication to get rid of it.
If your acne HAS responded to some topical treatments in the past, there are a few general acne treatments that work well. Drinking lots of water is key for good health, as is having a balanced diet. If your hair is oily, keeping it off your face is good (headbands and hair ties). If your skin is dry with acne, dabbing tea tree oil on the problem areas can help heal them. If your skin is oily with acne, dabbing straight apple cider vinegar is a better option. Some people respond well to benzoyl peroxide - when I had acne, it never did much for me besides making my skin flaky and peeling. Aspirin masks are very good at exfoliating and minimizing blemishes, but do a test spot on your arm first to make sure you're not too sensitive. Use a gentle cleanser, like Dove Beauty Bar or Cetaphil or whatever else it is that you've found to work well for you. Taking Biotin supplements (a type of Vit. B) can also have a beneficial effect.
Most importantly, you need to learn not to over-treat it. Often, a medicated cleanser + alcohol toner + moisturizer system is just product overload and can make your skin flare up even more (if you strip it of natural oils, this may kick oil production into overdrive). Less is usually more when it comes to these things.
