Best Practices to Keep Your Skin Healthy

• Regular Cleaning: Make a point to clean your COROS watch on a routine basis, and wash your hands and wrist with gentle soap and water following exercise or prolonged usage. 
• Allow the Skin to Breathe: Especially after activities that induce heavy sweating or following water-related activities, allow the skin underneath your watch to breathe and recover by removing the device from your wrist. Follow similar considerations during periods of long-term daily usage by swapping wrists that the watch is worn on.  
• Be Aware of Trace Mineral Contact: Although COROS watches are not made specifically with nickel, there may be trace amounts present in the metal alloy used to construct specific components of the device. The usage of a charging port cover (available for purchase on Amazon or AliExpress) is a great way to help reduce potential irritation for those with skin sensitivities. 
• Seek Medical Advice: If you experience persistent skin irritation, consult with your family doctor, or with a board-certified dermatologist, for proper diagnosis and treatment.
