<unk>  will typically resolve by itself in 2-6 months. In mild cases, cleansing the face daily with gentle soap and water while avoiding use of potential comedogenic soaps, lotions and oils is often enough. Further treatment is not necessary but in severe or persistent cases topical therapy can be initiated. Benzoyl Peroxide Topical benzoyl peroxide (BPO) may be indicated in persistent or inflammatory cases. BPO is a lipophilic agent that penetrates into sebaceous glands and generates reactive oxygen species that kill P. acnes. It also has comedolytic and anti-inflammatory properties and can prevent development of antimicrobial resistance. Topical Retinoids Topical retinoids can be used alone or in combination with BPO. Retinoids are derived from vitamin A. They bind to retinoic receptors to normalize the rate of keratinocyte growth and prevent inflammation. Overactive keratinocyte production can lead to comedone formation. Topical Antibiotics In cases where scarring is a concern, topical antibiotics may be recommended. Topical clindamycin and erythromycin are the most commonly prescribed options for acne. Antibiotics kill P. acnes on skin that could be causing inflammation. With the emergence of resistant P. acnes, experts recommend topical antibiotics to be used in combination with BPO to reduce the risk of development of antimicrobial resistance. The most common side effects of topical antibiotics are stinging, burning and redness at the site of application. Topical antifungals Some experts suggest the use of topical ketoconazole in newborns with more pustular<unk>  as there is evidence it shortens duration of lesions.
