Topical Isotretinoin: Current Applications, Challenges, and Future Directions

Topical isotretinoin is designed to work locally on the skin with limited systemic absorption and is being explored as a potential alternative to more commonly used topical retinoids. However, limited research, formulation challenges, and regulatory hurdles have slowed its path to widespread use. It appears to perform similarly to other topical retinoids and may offer added benefits such as improved tolerability and greater formulation stability. Additionally, its ability to integrate into combination therapies may further enhance its clinical utility. Despite these benefits, the lack of extensive randomized controlled trials limits understanding of its optimal use, long-term effects, and safety profile. Future research is essential to determine its role in dermatologic treatment, but its potential to expand therapeutic options remains promising.
