@dr.farzan: Tretinoin can help improve the appearance of atrophic scars by promoting collagen production and increasing skin cell turnover. Over time, it can smooth the skin’s texture and reduce the depth of scars. However, it works best for mild to moderate scars and may need to be combined with other treatments like microneedling or laser therapy for more significant results. Always use sunscreen with tretinoin, as it can make your skin more sensitive to the sun. #acnescars #scar #acneskin
