Do they leave a sticky residue when removed? Patches are made with hydrocolloid, a moisture-absorbing material commonly used in medical dressings. After extended time of wear, you may notice slight stickiness or a residue. It is completely normal and not a cause for concern. How long should I leave the patch on? We recommend 6 to 8 hours. For daytime patch, it is generally safe to wear them for up to 12 hours. What is the difference between Daytime and Overnight patches? While some products offer a single patch for all-day use, we provide Day and Night patches to meet different skin needs and lifestyle demands. Daytime is designed to be ultra-thin, and Night patch is to help protect and soothe the skin overnight. We are always with you. That's what real skincare means to us.
