Short answer is YES. It is a type of infection of the skin, caused by changes in the sebaceous glands. The most common form of it is called vulgaris, which literally means "common acne". So, the redness comes from the inflammation of the skin in response to the infection. Therefore, oils from the glands combine with dead skin cells to block hair follicles.
Symptoms range from uninflamed blackheads to pus-filled pimples or large, red, and tender bumps. It can also results in depression and dark spots on the skin.
