Thin and comfortable to wear, panty liners are a very versatile product. They can be used in many different situations. For example, if you are using a tampon, you might like to use a panty liner, too, for a little extra protection. You might also like to wear a panty liner when you don’t have your period, to help absorb normal vaginal discharge, perspiration (sweat). Pads are thicker and more absorbent than panty liners. They can offer you better protection when your menstrual flow is heavier. Panty liners can be worn any time you want to feel a little fresher and more protected.
