Step-by-step explanation:
The most appropriate initial step in the management of this patient with facial acne is topical retinoid. Acne is a skin condition that occurs due to the overproduction of sebum and blockage of hair follicles. Topical retinoids help to reduce inflammation and promote the shedding of dead skin cells, which can help to unclog the pores. They are considered as first-line treatment for mild to moderate acne.
