While the symptoms of acne vary in severity, you’ll notice these signs on areas of your body with the most oil glands (the face, neck, chest, back, shoulders, and upper arms):
Clogged pores (pimples, blackheads, and whiteheads)
Papules (raised lesions)
Pustules (raised lesions with pus)
Cysts (nodules filled with pus or fluid)
The least severe type of acne lesion is the whitehead or blackhead. This type is also the most easily treated. With more extensive acne, you may need prescription medications to ease inflammation, bacterial infection, redness, and pus.
