How do dermatologists layer or sequence treatments like BPO, retinoids, antibiotics, and azelaic acid for optimized efficacy?

This is a recording from Dr. Manjunath Hulmani explaining treatment options for acne vulgaris based on its severity or grade. The discussion covers management of Grade one and two acne with topical antibiotics such as clindamycin or minocycline, along with alternatives like benzoyl peroxide. For comedonal acne, topical retinoids including tretinoin or adapalene are recommended. In more severe cases, such as Grade three and four acne, a combination of benzoyl peroxide with adapalene is suggested as an effective approach, with emphasis on using a good moisturizer to manage dryness. The recording also highlights the benefits of azelaic acid for reducing active acne as well as post-acne pigmentation.
