The skin cells bursting on exposure to UV is a safety mechanism so that cancer does not result.

Explanation:

Sun burns are the result of cell's DNA being damaged by UV exposure and then the cells bursting to avoid tumor formation.

The cell DNA is the first thing that gets damaged due to UV exposure, the cell tries to repair itself by repair pathways, but when it is found irreparable, the cell bursts.
