Acne concerns

I've been really stressed out lately because of my acne. It used to only pop up occasionally, but these days, it's been recurring, especially on my chin and cheeks, and then subsiding. Even after the inflammation subsides, the red marks linger, making my skin look dirty. I've tried changing my cosmetics and adjusting my lifestyle, but nothing has changed. So, I'm wondering if I need professional care. I'm even more concerned because acne seems to be eroding not only my skin but also my confidence.
