Can fruit acid skin renewal remove acne scars and pits?

Glycolic acid skin renewal is a cosmetic procedure that promotes skin cell regeneration and accelerates the shedding of the stratum corneum by applying high-concentration glycolic acid. Generally, glycolic acid peeling can improve mild acne scars and pits; however, its effectiveness may be limited for deeper scars and pits. A detailed explanation is as follows:

Glycolic acid is a chemical exfoliating agent that removes the aged stratum corneum, promotes the generation of new keratinocytes, and also stimulates fibroblastic proliferation and reorganization of collagen fibers in the dermis. This improves skin texture, making acne scars and pits shallower, thereby achieving certain improvement effects on mild acne scars and depressions.

Deep acne scars and pits are usually caused by damaged skin tissue leading to collagen loss. Although glycolic acid peeling can promote collagen production, its effects on existing deep scars and pits may be limited. More effective treatments such as laser therapy, microneedling, or fillers may be required.

Before undergoing glycolic acid peeling, it is recommended to consult a professional dermatologist. During the treatment period, maintaining skin cleanliness and avoiding the use of irritating skincare products is important to prevent exacerbation of skin discomfort.
