  2. Regulating skin cell turnover, preventing clogged pores.
  3. Exhibiting anti-inflammatory effects that help diminish the appearance of acne lesions.

On the other hand, erythromycin is a macrolide antibiotic that helps by:

  1. Inhibiting bacterial growth, particularly Propionibacterium acnes, which contributes to acne development.
  2. Providing anti-inflammatory properties that can help reduce redness and swelling associated with acne.
