Can One Session of Glycolic Acid Peeling Help Acne Scars?

Glycolic acid peel for acne on the face?

I have had acne on my face for a long time.
I started seeing a doctor from October to November last year, and it has been persistent since then.
Recently, it suddenly flared up again.
Although there are fewer pimples now, there are still many, and I have significant post-inflammatory hyperpigmentation along with darker skin due to frequent sun exposure.
Can I undergo a chemical peel with alpha hydroxy acids just once and then continue using my medication?

Dr. Wu Yuxin reply Dermatology

I would recommend continuing medication treatment.
As for glycolic acid peels, whether they can be performed and how many sessions are needed would require a clinical evaluation.

More Info

Glycolic acid peeling, a form of chemical exfoliation, is often used in dermatology to treat various skin concerns, including acne scars. Glycolic acid, derived from sugar cane, is an alpha hydroxy acid (AHA) that works by loosening the bonds between dead skin cells, promoting their shedding and revealing fresher, healthier skin underneath. This process can help improve the appearance of acne scars, uneven skin tone, and texture.

To address your question about whether one session of glycolic acid peeling can help with acne scars, the answer is that while a single session may provide some immediate benefits, significant and lasting improvements typically require multiple treatments. The results from one session may include smoother skin and a slight reduction in the appearance of scars, but deeper scars or more pronounced discoloration often necessitate a series of treatments spaced several weeks apart. This allows the skin to heal and regenerate between sessions, maximizing the benefits of the treatment.

In your case, since you have been dealing with persistent acne and scarring, it may be beneficial to incorporate glycolic acid peeling into your overall treatment plan. However, it is crucial to continue using any prescribed medications alongside the peeling treatment. Many dermatologists recommend a combination approach, where chemical peels are used in conjunction with topical treatments or oral medications for acne. This can enhance the overall effectiveness of your skincare regimen.

Additionally, it is essential to consider your skin type and any potential sensitivities. Glycolic acid can cause irritation, especially for individuals with sensitive skin or those who are new to chemical peels. Therefore, it is advisable to consult with your dermatologist before proceeding with the treatment. They can assess your skin condition, recommend an appropriate concentration of glycolic acid, and determine the best treatment schedule for your specific needs.

Moreover, since you mentioned that your skin has been exposed to the sun, it is crucial to prioritize sun protection. Chemical peels can make your skin more sensitive to sunlight, increasing the risk of hyperpigmentation. Using a broad-spectrum sunscreen with an SPF of 30 or higher daily is essential, especially after undergoing a glycolic acid peel.

In summary, while one session of glycolic acid peeling may provide some benefits for acne scars, a comprehensive treatment plan that includes multiple sessions and ongoing use of prescribed medications is likely to yield better results. Always consult with your dermatologist to tailor a treatment plan that suits your skin's unique needs and to ensure safe and effective care.
