Banish Acne for Good: The Key to Long-Term Clear Skin Beyond Doctor Visits

Acne can be a persistent problem, with many people struggling with recurring breakouts and lingering scars. While seeing a dermatologist is crucial, there are essential skincare steps you can take to manage and prevent acne effectively.

Understanding Acne: The Role of Good and Bad Bacteria

Why Does Acne Keep Coming Back?

Dr. Gao Peihan explains that recurring acne is often linked to an imbalance of the skin’s microbiome, particularly the presence of Propionibacterium acnes and Staphylococcus epidermidis. When the balance between these bacteria is disrupted, it triggers the immune system, leading to inflammation and acne development. Maintaining a healthy balance of these bacteria is crucial for long-term acne management.

Traditional Treatments vs. Modern Approaches

Traditional acne treatments often focus on using antibiotics or other antimicrobial agents to reduce bacteria on the skin. However, these methods can also harm beneficial bacteria. Modern dermatology emphasizes enhancing the balance between good and bad bacteria to achieve better results.

La Roche-Posay’s Solution for Acne-Prone Skin

La Roche-Posay has been at the forefront of skin microbiome research since 2018. In 2024, they introduced an upgraded version of their Effaclar Duo+M, incorporating their exclusive MICROBIOME SCIENCE technology to address acne-prone skin.

Clinical Results

Clinical trials under dermatological supervision have shown significant results:

  • Reduction in Acne Size: 78% reduction in acne size within 8 days of continuous use.
  • Prevention of Recurrence: 67% reduction in the likelihood of acne recurrence with long-term use.
  • Improvement in Acne Severity and Pigmentation: Noticeable improvements in the severity of acne and reduction of pigmentation.

Enhancing Acne Treatment with Skincare

Dr. Gao Peihan suggests that incorporating Effaclar Duo+M into your routine alongside prescribed medications can enhance treatment efficacy. Apply topical acne medication first, followed by Effaclar Duo+M. Its lightweight, non-greasy texture absorbs quickly, providing gentle hydration that minimizes the irritation often caused by acne treatments. This combination can accelerate healing and improve overall results.


To effectively manage and prevent recurring acne, it’s essential to balance the skin’s microbiome. Incorporating products like La Roche-Posay’s Effaclar Duo+M, which supports the growth of beneficial bacteria while controlling harmful ones, can make a significant difference. Consult with your dermatologist and integrate these steps into your skincare routine for long-term clear and healthy skin.
