Panty liners are thin, absorbent pads designed for daily use to maintain freshness and provide light protection. These products typically adhere to the inside of underwear and offer a discreet layer between clothing and the body. They serve a different purpose than menstrual pads, which are designed to manage heavier menstrual flow.
The adoption of these products stems from a desire for cleanliness, comfort, and confidence. They can absorb light bladder leaks, spotting between periods, or vaginal discharge. Furthermore, they can protect underwear from everyday soiling and staining. Historically, simpler forms of absorbent materials have been used for similar hygiene purposes, evolving into the modern panty liner designed for convenience and effectiveness.
