This is how sensitive I found out my skin is:
When I put on my mascara in the morning, I hold the eyelash curler with my lips. It’s just out of habit, so that it’s not freezing cold when I put it to my eyelids. Well I’ve had a slight rash below my bottom lip for the past few weeks, and I’ve been trying to figure out what’s been causing it. And this morning, I got it: it’s where the eyelash curler touches my skin – for all of 10 seconds per day.
I should have known better. The metal backside of jean buttons also gives me a rash. I have to put nail polish on them to make sure it doesn’t touch my skin. That took me about 6 months to figure out when it first started happening.
