Excess Sebum Production
Another cause of chin acne is the excess production of sebum. On the majority of the body, microscopic sebaceous glands that create sebum are located just below the skin’s surface.
Sebaceous glands are typically found in greater numbers on the face, neck, chest, shoulders, and back than everywhere else on the body. There aren’t many, if any, sebaceous glands on the soles of the feet and palms of the hands.
Through pores near the hair follicles, sebum usually rises to the surface. The skin is effectively waterproofed by sebum, which also lubricates and protects it. Dry, cracked skin can result from insufficient sebum. A follicle with too much sebum may develop a solid plug, which may later result in different types of acne.
Once inflammation starts in a sebum plug, it will result in a papule, which appears like a pimp bump on the skin’s surface. This bump can also feel tender when touched. Moreover, a papule can later become a lesion filled with pus, also known as a pimple. Pimples are acne that typically has a red center. Meanwhile, when a bulging patch of skin called pustule is full of pus, a yellowish fluid, it’s called a cyst, which needs dermatologist care.
