Reddish brown scaly spots, mostly found on the arms and legs. Can show up on other sun-damaged skin. Caused by abnormal sun sensitivity. Often associated with precancerous skin cells.


Dr. Harlan typically treats his adult patients for DSAP by having them apply SmartLotion® 2x per day for up to 4 weeks along with a cholesterol containing cream from a compounding pharmacy.
