Laura Timares was unintentionally left off the list of authors. She should have been listed along with her affiliation, Department of Dermatology, University of Alabama at Birmingham, Birmingham, AL, USA. Her NIH funding sources, R21AR055252 and P30AR050948 should also have been listed.

The authors regret the errors.
