How Do You Really Get Clear Skin?

I know this question has probably been asked a million times on this site but anyway is it even possible for me at the stage of my life to reverse my current skin condition to have perfect, flawless skin? The main reason why I started the parasite cleanse was to clear my skin; and that has been an issue of mine for the past 14 years. But six months later of different parasite treatments, my Acne has never once cleared up. I guess my main weakness is being consistent. It's extremely hard to be consistent with a diet, sleeping pattern, regimen, etc. living in poverty. But if consistency is the key to clear skin I apology for wasting your time guys but if anyone out there has a success story I'd love to hear it. And on another note, I am Black so not only do I struggle with acne, but I also struggle from skin discoloration, Acne marks but the hundreds, and some Acne scars. As a guy it's embarassing to say this but I have to put on makeup when I go out in public just to hide all the marks. My face looks like I have freckles except they are acne marks! So if it's getting into a consistent routine, whether diet, cleanse, environment clean up or change to get clear skin please let me know. And to repeat the concern, what I'm looking for is to pretty much reverse my skin condition from serious acne sufferer to having smooth baby like skin (minus the acne scars, I know they're almost impossible to get rid of I can live with that, I can't live with all of the cyst/pimples/whiteheads/acne marks on my face though) Thanks again
