How long does it take for acne marks to fade on their own?

The duration required for the disappearance of acne marks varies individually and is mainly influenced by the severity of the acne marks, the patient's skin type, skincare regimen, and other related factors. Generally, it takes 1 to 6 months, or even longer, for acne marks to fade. Below is a detailed analysis of the duration required for acne mark fading: 1. Superficial acne marks: These types of acne marks usually have a lighter color and recover more quickly. Typically, superficial acne marks fade within about two weeks. 2. Moderate acne marks: These acne marks are somewhat redder and deeper, reaching the superficial layer of the dermis. They may require 1 to 2 months to disappear completely. 3. Deep acne marks: Acne marks that extend beyond the deep layer of the dermis may develop into scars and fade more slowly. Reddish acne marks of this type usually take 3 to 6 months to fade. Larger and deeper acne marks requiring collagen fiber repair may take several months or even longer to fully recover.
