AHA vs BHA for Ingrown Hairs and Dark Spots After Waxing
Question
I want to treat ingrown hairs and dark spots on my legs after waxing. Which is better, AHA or BHA? I was previously advised to wait 1 week before using Glycolic Acid, Lactic Acid, or LHA for peeling. Why should I wait, and what are the pros and cons of AHA and BHA for these issues?
Answer
AHA vs. BHA for Ingrown Hairs and Dark Spots After Waxing
You're asking whether AHA or BHA is better for treating ingrown hairs and dark spots on your legs after waxing. This is a common concern, and both types of exfoliants can be helpful, but they work slightly differently.
Understanding AHA and BHA
- AHA (Alpha Hydroxy Acid): Ingredients like Glycolic Acid and Lactic Acid. These are water-soluble and primarily exfoliate the surface layer of the skin. They are effective for improving skin texture and reducing the appearance of dark spots (hyperpigmentation).
- BHA (Beta Hydroxy Acid): The most common is Salicylic Acid. This is oil-soluble and can penetrate deeper into pores and hair follicles. BHA is excellent for clearing blockages, which makes it particularly useful for preventing and treating ingrown hairs. LHA (Lipo Hydroxy Acid) is a derivative of Salicylic Acid and is often considered a gentler option.
Which is better for your concerns?
- For dark spots, AHA can effectively exfoliate the pigmented surface cells.
- For ingrown hairs, BHA (like Salicylic Acid or LHA) is often more targeted because it can get into the follicle to help release trapped hairs.
Given you have both issues, both types could be beneficial. The previous advice you received mentioned Glycolic Acid, Lactic Acid (AHAs), and LHA (related to BHA) as options.
Crucial Step: Wait After Waxing
The advice to wait at least one week after waxing before using exfoliants is very important. Waxing irritates the skin, and applying chemical exfoliants too soon can cause significant irritation, redness, or discomfort. Allow your skin time to heal first.
Recommendation:
- Wait: Absolutely wait at least one week after waxing before starting any chemical exfoliation.
- Choose an Exfoliant: Consider a product with BHA (Salicylic Acid or LHA) if ingrown hairs are your main issue, or AHA (Glycolic or Lactic Acid) if dark spots are more concerning. Many products combine these ingredients, or you could use them alternately.
- Start Gently: Begin with a low concentration and use the product infrequently (e.g., 2-3 times per week) to see how your skin responds. You can increase frequency gradually.
- Patch Test: Test the product on a small area first.
- Moisturize: Keep the skin hydrated.
- Sun Protection: Exfoliated skin is more sensitive to the sun. Protect the area from sun exposure.
