Daily use of an AHA body wash can irritate the external vulvar skin and cause burning, especially because vulvar tissue is much more sensitive than the skin on most of the body.
That doesn’t mean an AHA body wash automatically disrupts the vaginal microbiome. The bigger concern is where the product is being used and whether it is irritating the surrounding skin.
Your vulva and vagina aren’t the same thing
The vulva is the external genital area. The vagina is the internal canal.
An AHA body wash used around the external genital area can irritate sensitive vulvar skin. But that is different from proving that the product has altered the vaginal microbiome.
The vagina has its own microbial environment, and putting body washes, acids, fragrances, or other cleansing products inside the vagina isn’t necessary for routine hygiene.
Why can an AHA burn down there?
AHAs such as glycolic acid and lactic acid are exfoliating acids. They’re designed to loosen connections between surface skin cells.
That’s useful for certain body-skin concerns, but vulvar skin doesn’t need to be exfoliated like your elbows or knees.
Daily exposure can be especially irritating if the product is fragranced, concentrated, left on the skin, used after shaving, or applied to already-dry or damaged skin. Burning, stinging, redness, peeling, or rawness are signs to stop rather than push through.
What should you do if you’re burning?
Stop using the AHA product on the area.
Rinse gently with lukewarm water and avoid scrubbing, fragrances, deodorizing products, wipes, and additional acids while the skin settles. Wear breathable clothing and avoid anything that creates repeated friction.
You generally don’t need to wash inside the vagina. For the external area, gentle cleansing with water or a mild, fragrance-free cleanser that you already tolerate is usually enough.
If burning, itching, unusual discharge, odor, sores, swelling, or pain persists, get evaluated rather than assuming you’ve simply “over-exfoliated.” Several vaginal and vulvar conditions can cause similar symptoms and require different treatment.
And your body wash doesn’t need to go everywhere
AHAs can be useful for rough, textured body skin. That doesn’t mean every inch of skin needs the same routine.
Keep your exfoliating body products on the areas they’re designed for and leave the vulva out of the acid experiment.
Your elbows may want glycolic acid. Your vulva absolutely does not need to join the group project.
