Which of the following is NOT a common treatment option for acne?

Antihistamines are not a common treatment option for acne. They are primarily used to relieve allergy symptoms, such as sneezing, runny nose, and itching. Acne is primarily driven by factors such as excess oil production, clogged pores, bacteria, and inflammation.

On the other hand, Vitamin A is a well-known treatment that helps regulate skin cell production and prevent clogged pores, making it beneficial in acne management. Antibiotics are used to combat the bacteria associated with acne and reduce inflammation, effectively addressing one of the key contributing factors. Retinoids, which are derivatives of Vitamin A, are also commonly prescribed for acne as they help to unclog pores and promote skin renewal.

In summary, while Vitamin A, antibiotics, and retinoids directly target the underlying causes of acne, antihistamines do not play any significant role in acne treatment.
