We all have our scars, whether they're from a surgery, inflamed acne, or, in Dr. Johnson's case, a classic run-in with a chainlink fence as a teenager. By now you've no doubt heard the myths (to let a wound 'air out'), the misunderstandings (that every wound needs Neosporin), and the unsubstantiated claims (essential oils might smell nice but that may be all). In this episode of Skincast, our board-certified dermatologist hosts explain how scars are formed, how we can help them heal, and even some solutions for improving a scar's appearance over time.
