Glycolic acid, an alpha-hydroxy acid (AHA), is a popular ingredient for lightening underarms. It works by exfoliating the top layer of skin, revealing brighter skin underneath.
Here's how glycolic acid can help lighten underarms:
- Exfoliation: Glycolic acid removes dead skin cells, which can accumulate and cause darkening. This helps to even out skin tone and reduce hyperpigmentation.
- Increased Cell Turnover: It encourages new skin cell growth, promoting a brighter and more even complexion.
- Penetration: Its small molecular size allows it to penetrate the skin deeply, effectively targeting dark spots.
To lighten underarms with glycolic acid, consider these steps:
- Choose a product: Look for a product specifically formulated for underarms or body, containing a low concentration of glycolic acid (2-5%) for initial use.
- Patch test: Before applying to your entire underarm area, perform a patch test on a small area of skin to check for any sensitivity.
- Apply regularly: Apply the glycolic acid product to clean, dry underarms once or twice a day, depending on the product instructions.
- Moisturize: After applying glycolic acid, follow up with a gentle moisturizer to prevent dryness.
- Sun protection: Always use sunscreen on your underarms, as glycolic acid can make your skin more sensitive to the sun.
Remember:
- Results may take time and consistent use.
- Consult a dermatologist for personalized advice and to rule out other causes of underarm darkening.
- If you experience any irritation or discomfort, discontinue use and consult a dermatologist.
