I recommend reaching out to Product Support through their website at https://support.garmin.com. Use the Phone or Chat options. Email exchanges take a lot of time.
As stated by Garmin...
Any user who experiences any sort of skin irritation will need to reach out to us directly at support.garmin.com. We will need to gather information from you that we would not ask for in a public forum. These complaints are taken seriously and we will work to find the most suitable solution as quickly as possible.
