I have a lot of small red raised acne bumps and clogged pores on my back, mostly on my shoulder blades. what causes them and how do i get rid of it??

Acne: Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Acne can be inheritable and often if your parents had acne when they were your age, you may be more prone to get acne as well. Some people produce more oil then others, etc. Drying soaps and "Acne washes" can help. Sometimes low-dose antibiotics can be Rx'd by your doctor, creams, etc. See your Doctor.
