If acne is not treated properly or promptly, it may worsen and develop into cystic acne. Additionally, if individuals frequently scratch, squeeze, or pick at the acne during treatment, infections can form and ultimately result in residual scarring. Once scars have formed, they are not easily fully repairable. If the scar proliferation is not too severe and is relatively flat, fractional laser treatment can be temporarily used for repair. If the scar proliferation is more pronounced and protrudes significantly, it is necessary to seek treatment in a proper hospital with medications and injections for closure therapy. However, these methods can only temporarily soften or shrink the scars, and cannot completely remove them. Therefore, the most fundamental approach is still to manage the treatment effectively to prevent residual scarring. Upon detection, it is crucial to follow standardized treatment protocols and avoid scratching or bursting the acne.
