Good skin care routine on a budget???

My skin is starting to break out bad and I have hyperpigmentation on my forehead, mustache area and slightly on my chin and I really wanna get it under control bc without make up and flash photos, you can REALLY see the hyperpigmentation. I’m getting self conscious bc im also gaining weight so I just want to get my old skin and body back. Does anybody have any helpful tips, tricks, advice or recommendations for a good skin care routine on a budget?? I know eating healthy and exercise is one of the ways to getting better skin. i am already working on that
