Chemical Peel left the skin on my underarms darker. Can anything be done to lighten this?

Addressing Post-Chemical Peel Hyperpigmentation in the Underarms

Experiencing darkening of the skin after a chemical peel can be concerning, especially in sensitive areas like the underarms. Here are some steps you can take to address this issue:

1. Understanding Post-Inflammatory Hyperpigmentation (PIH):
The darkening of the skin you're experiencing is likely post-inflammatory hyperpigmentation (PIH), a common response to skin irritation or injury.
This can happen when the skin is exposed to peeling agents, especially if not used under professional guidance.

2. Gentle Skin Care Routine:
Use mild, fragrance-free cleansers and moisturizers to avoid further irritation.
Avoid scrubbing or using harsh products in the affected area.

3. Topical Treatments:
Over-the-counter products containing ingredients like niacinamide, vitamin C, or licorice extract can help lighten hyperpigmented areas.
Consider consulting with a dermatologist about prescription options such as hydroquinone, retinoids, or azelaic acid, which can be more effective for PIH.

4. Sun Protection:
Protect the area from sun exposure, as UV rays can worsen hyperpigmentation. Use a broad-spectrum sunscreen if the area is exposed to sunlight.

5. Professional Treatments:
If over-the-counter treatments are not effective, a dermatologist can offer in-office treatments such as chemical peels, laser therapy, or microneedling, which may help lighten the skin.

6. Patience and Consistency:
Skin lightening takes time, and consistent application of treatments is key. It may take several weeks to see noticeable improvement.


It's important to consult with a dermatologist to tailor a treatment plan specific to your skin type and condition, ensuring safe and effective results. Avoid self-treating with strong peels or products without professional guidance to prevent further irritation or damage.
