@dr.farzan: Tretinoin can significantly improve the appearance of acne scars over time by promoting collagen production and enhancing skin texture. However, results are gradual and best for mild to moderate scars. For deeper scars, combine tretinoin with professional treatments like microneedling or lasers for optimal results. Patience and consistent use are key to achieving smoother skin. #acnescars #acnemarks #scar #tretinoin #skincare
