Acne affecting the face, back, and chest can take time to improve, and your treatment with Isotretinoin, Erythromycin gel, and a hyaluronic acid mask is appropriate for moderate to severe acne, so the most important step is to use these regularly exactly as prescribed and be patient, as improvement may take several weeks. Keep your skin care simple by washing gently twice daily, avoiding harsh scrubs or oily products, and using non-comedogenic moisturisers and sunscreen, since isotretinoin can cause dryness and sun sensitivity. Avoid picking or squeezing pimples to prevent scars. Maintain a balanced diet and reduce stress, which can worsen acne. Regular follow-up with your doctor is important to monitor for side effects of isotretinoin (like dryness or changes in liver tests) and adjust the dose if needed. With consistent treatment and care, most people see significant and long-lasting improvement.
