On Dec. 14, the Food and Drug Administration approved a first-of-its-kind liquid called Eskata that targets these unsightly spots. By late April, people who have the means and the patience to sit through at least two visits to their dermatologist’s office can get rid of some raised spots.

Here’s how Eskata works: After a dermatologist has determined a spot is not cancer, a staff person (not necessarily a doctor) delicately applies the highly concentrated hydrogen peroxide liquid to each lesion four times, roughly a minute apart. The idea is to moisten the lesion to dissolve it, while avoiding damaging surrounding skin.
