Apple Watch Burns

You seem to have very fair skin that will not tolerate overnight use.

my personal advice if you have such delicate skin:

·       Wear it on the other wrist til the skin heals

·       Wash your wrists night and morning

·       Do not wear it overnight!

·       Clean the watch back and strap with a damp face cloth every day

·       Moisturise at night and if you have a dusty job  apply barrier cream in the morning.

·       If it persists see a dermatologist.

By the way, if the tattoos cover the area under the watch back any heavier than they currently are, most if the heart and blood features and workouts will fail to work.
