The skin on my fingertips tends to be very dry and develop painful cracks, mostly during the colder months of the year but that can happen in warmer months, too. The moisturizers and ointments that the dermatologist recommended don’t help a lot. So she has recommended Narrow-Band UV-B phototherapy to treat the skin on my fingers. The down side is that there is a small risk of developing skin cancer, so I am hesitating to try the phototherapy. Have any of you tried phototherapy for this type of skin problem, and has it helped? Thank you.
