Connecting inflammatory acne to your symptoms

Red pimples and deep nodules have different risks of scarring

The speed and priority of treatment vary depending on whether small papules and pustules primarily occur, or whether deep, painful nodules recur. Deep inflammation may need to be subsided before extraction.

Korean herbal medicine treatment considers both inflammation and recurrence conditions

Along with reducing current redness, pain, and heat, we check how sebum, the skin barrier, and menstruation, sleep, and digestion overlap with recurrence. We determine the focus of treatment without excluding necessary dermatological medications or procedures.
