The areas start out very much like a hive (red, blotchy, extremely itchy skin), but, unlike hives, end up leaving a red papule with the occasional white center that stick around for days to weeks. To provide some context, this all started after seeking treatment
for mild acne (
whiteheads on my forehead and extremely oily skin) about 3 years ago. The dermatologist I saw then prescribed Ziana gel, which worked relatively well (never completely cleared the whitehead problem, though it helped).
