Atopic dermatitis (AD) is a common chronic pruritic inflammatory cutaneous disease. AD is characterized by intense pruritus and enormous clinical heterogeneity. Treatment goals are to improve skin lesions and minimize exacerbations and symptom burden. Currently, topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI) are still considered the main topical therapies in disease treatment. However, despite being very effective, TCS and TCI are not recommended for continuous long-term use, due to potential safety issues. Although research in AD has focused primarily on systemic drugs, more than 20 new topical compounds are under development to treat the disease. This review aims to provide a synthesized summary of the current knowledge about AD topical treatment, echoing existing gaps and coming research trends. The available data seems promising, with some drugs already approved (ruxolitinib being the most recent), and several are in an advanced stage of development and will soon be available for treatment of mild to moderate disease, namely tapinarof, difamilast, and roflumilast. However, longer and larger prospective studies are needed to assess the long-term efficacy and safety of these new compounds and evaluate their benefits over current treatments.
