What You Need to Know About the 6 Different Types of Acne⁠

Let’s talk about acne. Acne is an inflammatory skin condition where hair follicles become clogged with dirt, oil, and/or dead skin cells.⁠ Acne forms when an overproduction of sebum or keratin clogs pores. ⁠Sebum is an oily substance that can build up and clog pores due to genetics or hormonal imbalances.⁠ Whereas, keratin is a protein that makes up your hair, skin, and nails. Too much keratin can cause dead skin cells to stick together and become trapped in the pore.⁠

Keep reading to learn about the driving force behind the 6 different types of acne, signs and symptoms to watch out for, and appropriate lab tests for each one.⁠
