Yes: Zinc oxide is a barrier against uv rays. It will minimize pigmentation in your skin from the sun. If darkened skin is your concern it will help. If the scars are red time will help these areas to resolve. However limiting sun exposure is preferable. If you can't avoid direct sun light then zinc oxide will help protect the skin.
