Azelaic acid is generally not able to repair acne pits and can only be used as a topical treatment for mild to moderate inflammatory acne vulgaris.
Azelaic acid is only effective for mild to moderate inflammatory acne, so it cannot work to repair acne pits. During the use of azelaic acid, some patients may experience adverse reactions such as itching, burning and stinging. The use of the drug is prohibited for patients who are allergic to it.
Acne pits are a type of scar left on the surface of the skin after acne and other lesions subside, also known as depressed scarring and atrophic scarring. The effect of medication alone is mild. Clinical superficial scarring and hyperplastic scarring can be enough to be treated by laser and intense pulsed light, chemical peeling, dermabrasion, micro-needling, tissue fillers, and surgical procedures.
Patients who use azelaic acid to treat diseases need to be under the guidance of a professional doctor and use it wisely.
