What class of medications is considered standard care for severe acne?

Oral antibiotics are considered standard care for severe acne due to their ability to reduce inflammation and bacterial load in the skin. Severe acne often involves more significant inflammation and may also be associated with an overgrowth of skin bacteria, particularly Propionibacterium acnes, which contributes to the development of acne lesions.

By systemically administering antibiotics, the treatment targets these bacteria and decreases the overall severity of the acne. Commonly prescribed oral antibiotics include tetracyclines (such as doxycycline and minocycline) and sometimes sulfonamides or macrolides, depending on the patient's needs and any existing contraindications.

While other treatment options, such as Vitamin A (in the form of retinoids) and topical steroids, can play a role in managing acne, they are not typically the first line for severe cases. Instead, they serve to complement antibiotic therapy or are used in different contexts of acne management. Petroleum cream is not indicated for acne treatment, as it can potentially exacerbate the condition by occluding the pores.
