What is the treatment for acne?

Hi doctor,

I have been trying lots of remedies and treatments for acne as I thought it was acne. I usually get a butterfly-shaped redness across my cheeks and nose bridge. I turned so red easily when I exercised, was shy, or embarrassed, and I had never had issues like this before until two years ago. There are a lot of bumps that keep appearing and most of the time it would not come to a head, like an underneath papule or pimple, and take about one to two weeks to disappear. Even without exercising, my cheeks are always pinkish. And, sometimes around my period, my face feels so hot and appears so red mainly on the cheeks and forehead, sometimes on the chin too. Whenever I stand beside my sisters, their faces are usually white or a little pinkish after they exercise. But mine is so red compared to them even without exercising. So, I did a lot of research on this and my best guess is papulopustular rosacea but I am still not 100 percent sure.

Thanks.
