I remember hearing the announcement of how a clothing manufacturer began using ‘tagless’ tags and thought - interesting idea.
A resounding ‘no’ is in effect now.
The tagless tag is made from a slew of chemicals and appears to be too strong of a mix. The photos show a classic chemical burn.
Many times the old ways are way better than the new -
Whenever there is an isolated patch that does not make sense - think:
When did this start? What have I changed recently? Laundry detergent? Sheets? Clothes? Lotions? What is the skin in contact with day after day?
Topical vitamin E and aloe vera may help the skin heal.
If ulcerated, do not apply anything without taking your child to a physician.
