Have you ever noticed pale or faded patches on your underwear and wondered whether you accidentally used too much bleach or detergent?
You’re not alone.
The unusual-looking marks have caused plenty of confusion, but in many cases, they can have a completely natural explanation.
The discoloration is often associated with the vagina’s naturally acidic environment. Vaginal pH is normally lower than neutral, and this acidity is part of the body’s natural protective system. Rather than automatically being a sign of poor hygiene, lighter areas on underwear can simply result from normal vaginal secretions interacting with the fabric.
