The purpose of this research study is to collect skin samples from volunteers with HS and volunteers with healthy skin. The collected skin samples will be processed and compared to each other to see if there are specific differences in the skin between the HS volunteer group and the healthy skin volunteer group.

Participants will need to come to a one-time, in-person visit where biopsies (small skin samples) will be collected. - For participants with HS: Up to 4 biopsies will be collected - For participants with healthy skin: Up to 2 biopsies will be collected
