Wearing a liner 24/7 isn't usually necessary, and it's not always the most comfortable choice either. Liners are designed for specific moments, light spotting, the tail end of your period, daily discharge, or backup with a tampon or cup. Wearing one constantly can keep moisture against your skin, and some people find that bothers them over time. If you feel like you need a liner every single day, that's worth a conversation with your doctor to rule anything out. When you do wear one, pick a breathable option like Rael's organic cotton cover liners and change it every few hours. Your body will tell you what it prefers.
