Recently, the area around my mouth has been constantly red and the itching has worsened, so I visited a dermatologist. At first, I thought it was just simple dryness, but it started to sting and peel, which really bothered me. In the examination room, Dr. Hong Eun-ji carefully examined my skin condition with a magnifying glass and asked detailed questions about the cosmetics and foods I had recently used, as well as changes in the weather. As a result, I was diagnosed with allergic angular cheilitis, and she explained that my symptoms had worsened due to a combination of irritation and allergic reactions. To minimize irritation, the treatment initially involved a prescription for a hypoallergenic steroid ointment and antihistamines, along with skin soothing, cooling, and moisturizing care at the clinic. When a cooling pack was applied during the soothing session, I immediately felt the itching subside, and my skin felt more comfortable overall. They also provided detailed instructions on how to select moisturizing products and cleanse at home, which was a great help in managing my condition. What I liked about this hospital is that they didn't just prescribe medication; they accurately explained the cause of my symptoms and even provided lifestyle management tips to prevent recurrence. Two to three days after treatment, the redness subsided significantly, and after about a week, the itching had almost completely disappeared.
