Brief Summary

In the effort to find better treatments for Moderate Acne, which often relies on long-term antibiotic use, researchers are exploring alternative options. While Isotretinoin, a Vitamin A derivative, is highly effective for severe acne, its side effects limit its use for milder cases. A recent study from our institution investigated a new approach: weekly Isotretinoin dosing. The results were promising, with acne improvement and no major side effects. This suggests that weekly Isotretinoin could be a successful alternative for moderate acne in both males and females. To validate these findings, investigators propose a randomized controlled trial comparing weekly Isotretinoin to daily Doxycycline over four months. This study could confirm the safety and effectiveness of weekly Isotretinoin, as well as shed light on patient satisfaction, and long-term results compared to standard antibiotics. This research may offer a breakthrough in treating moderate acne while addressing concerns about antibiotic overuse.
