Why is my skin so red, and how can I stop it?

I have quite red facial skin, and I do have some acne. It is not severe, but it is kind of bad. I just got Yaz yesterday so I hope my skin will start to clear up within about 4 months. But my skin is just really red, and usually kind of hot. I was thinking of buying that powder from Clinique that covers redness, but it is like thirty eight dollars. I would rather cure my red skin than cover it up. Does anyone know why my skin is red, and if it’s related to the acne? What tips, and things can I do to stop the redness?

Also I have kind of dry skin, but I mositurize it everyday. It used to be really oily when I was younger, but now it’s quite dry. I have benzyl peroxide (sorry for the typo) for my acne but it makes my skin even redder. I am a teenager (16) if that makes a difference.
