It depends. Some sunblock reflects uv back away from the skin. In this case none of that energy is absorbed by the body. Others absorb it and turn it into heat energy. The heat energy might cause some discomfort when transferred into the skin but won’t cause ionization of organic molecules which is what causes sun burn. Understand sun burn isn’t the same as a normal burn like you might get from a stove top.
