After taking off a pantyliner my vulva started itching

Okay so sometimes pantyliners can make your vulva itchy, it's pretty common actually. Your skin down there is super sensitive, and pantyliners can trap moisture or sometimes have fragrances or materials that just don't agree with you.

What to do about it

First, gently wash the area with just warm water, no soap, and pat it dry really well. Wear some comfy cotton undies and try to let things air out a bit. Skip the pantyliner for a day or two if you can, and if you have to wear one, maybe try a different brand or switch to unscented ones.

If it keeps itching, or if it gets red, swollen, or you notice any weird discharge, you should definitely tell a grown-up. They can help you figure out what's going on and if you need to see a doctor. Sometimes it's just a little irritation, but other times it could be something like a yeast infection, and a doctor can help with that.
