AHA Peels: Treatment Duration, Skin Care, and Safety Concerns

Alpha hydroxy acid (AHA) chemical peel

How long does a glycolic acid peel treatment take? During the treatment process, it is necessary to use sunscreen.
If the entire treatment is completed and the skin returns to normal, will my face darken if I forget to apply sunscreen one day? I have very noticeable acne and enlarged pores in my T-zone; can glycolic acid peels restore them to be the same as other areas? However, the skin on my cheeks near the eyes seems to be thinner and sometimes gets red in winter, and applying lotion can be painful.
If I undergo a peel, will it become sensitive skin? Also, is it necessary to take oral retinoids during glycolic acid peels? How long after treatment should I wait to become pregnant to avoid affecting the fetus? Thank you!

There are many different treatments for chemical peels.
Essentially, they stimulate the mid-dermis to promote skin regeneration and exfoliate the outermost layer of aged stratum corneum.
Low-concentration treatments are typically performed every 1-2 weeks, while high-concentration treatments are done every 1-2 months.
Chemical peels do not require the use of retinoids, and it is advisable to avoid retinoids during pregnancy.

More Info

AHA (Alpha Hydroxy Acid) peels are a popular treatment for various skin concerns, including acne, hyperpigmentation, and signs of aging. Understanding the treatment duration, post-care, and safety concerns is essential for achieving the desired results while minimizing potential side effects.

Treatment Duration
The duration of an AHA peel treatment can vary based on individual skin conditions and the specific type of peel used. Generally, a series of peels is recommended, often spaced about 2 to 4 weeks apart. A typical course may consist of 4 to 6 treatments, but this can be adjusted based on your skin's response. It's crucial to consult with a dermatologist to tailor the treatment plan to your specific needs.

Post-Treatment Care and Sun Protection
After undergoing an AHA peel, your skin will be more sensitive to sunlight. Therefore, diligent sun protection is paramount. You should apply a broad-spectrum sunscreen with at least SPF 30 daily, even on cloudy days, to prevent UV damage. If you forget to apply sunscreen on a particular day, there is a risk that your skin may darken or develop pigmentation issues, especially if you have a history of hyperpigmentation.

Addressing Specific Skin Concerns
For your T-zone, which has noticeable blackheads and enlarged pores, AHA peels can be effective in improving skin texture and clarity. The exfoliating properties of AHA help to remove dead skin cells and unclog pores, potentially leading to a more even skin tone. However, results can vary, and it may take several treatments to see significant improvement.

Regarding the thinner skin around your cheeks, which can be sensitive and prone to redness, caution is advised. AHA peels can sometimes exacerbate sensitivity, especially if the skin barrier is compromised. It’s essential to communicate with your dermatologist about your concerns, as they may recommend a gentler approach or alternative treatments to avoid irritation.

Combining Treatments
You asked whether AHA peels must be combined with oral retinoids like isotretinoin (commonly referred to as A acid). While combining treatments can enhance results, it is not mandatory. Many patients achieve satisfactory results with AHA peels alone. If you are considering oral retinoids, it’s crucial to discuss this with your healthcare provider, especially if you are planning to conceive in the near future.

Pregnancy Considerations
If you are planning to become pregnant, it is advisable to wait at least one month after completing any oral retinoid treatment before trying to conceive. This precaution is due to the potential teratogenic effects of retinoids, which can cause birth defects. Always consult with your healthcare provider for personalized advice regarding the timing of pregnancy in relation to any skin treatments you are undergoing.

Conclusion
In summary, AHA peels can be an effective treatment for various skin concerns, but they require careful consideration regarding treatment duration, post-care, and potential side effects. Always prioritize sun protection, especially after treatments, and communicate openly with your dermatologist about your skin's sensitivity and any concerns you may have. With the right approach, you can achieve healthier, more radiant skin while minimizing risks.
