Staphylococcal acne is a form of acne that is caused by the bacteria Staphylococcus aureus. It typically appears as red, swollen, and painful bumps or pustules on the skin. These bumps may be larger and more inflamed than typical acne lesions and can progress to form abscesses. Staph acne may also present with crusting, oozing, or tenderness. It is important to seek medical advice if you suspect you have staph acne as it may require treatment with antibiotics to prevent the infection from spreading.
