What is the best approach for severe, stubborn acne that doesn’t respond to over-the-counter treatments?

When over-the-counter cleansers and spot treatments fail, dermatologists typically move to a combination therapy. The most scientifically proven method is to tackle the acne from two angles simultaneously: fighting the bacteria and unclogging the pore. Treatments like Epiduo and Epiduo Forte are highly effective for this, as they combine both Adapalene (a retinoid to sweep the pore clean) and Benzoyl Peroxide (to eliminate bacteria) into a single powerhouse formula, making it vastly more effective than using either ingredient alone.
