I went to the dermatologist because the skin on my hands was cracked. The dermatologist said it wasn't severe and that moisturizing was important in the winter. Still, there were some cracked and red areas, so she prescribed ointment. The ointment wasn't strong, but she told me to use a small amount because too much could cause side effects. She also said a prescription wasn't necessary. Because the clinic was crowded, I'd recommend calling to inquire about availability before going. Fortunately, I was able to go to the clinic on my day off. The staff and doctor were all friendly, and the location, right at the Ajou University intersection, makes public transportation convenient for people living in Suwon.
