Scars left by acne can generally be categorized into atrophic scarring, depressed scarring, and hyperplastic scarring or keloid scars, which can be improved by laser, surgical excision, and fillers in terms of treatment.
1. Atrophic scar: Atrophic scar can be improved by carbon dioxide fractional laser, erbium laser, non-exfoliative fractional laser, micro-needling, radiofrequency and other treatments.
2. Depressed scar: For some large depressed scars, they can also be treated by filling or surgical excision.
3. Hyperplastic keloid and keloid: For hyperplastic keloid and keloid, which are relatively difficult to treat at present, hormonal topical sealing treatment, dye pulse laser, carbon dioxide fractional laser can be used.
For patients with post-acne scars, it is recommended to go to a regular hospital for timely examination and standardized treatment under the guidance of a professional doctor.
