Plants, just like humans, have sensitive skin. Even though plant skin is different in texture and look as ours, it somehow does not get sunburn from the sun. Why is that?
Researchers may have discovered a naturally produced sunscreen in plants that coats their leaves. A study published in the Journal of the American Chemical Society October 8, 2014 details such a finding. Overexposure to ultraviolet light in plants, as in humans, can cause damage to plant DNA. So there must be something plants synthesize internally that help protect them from the harsh sun rays.
The study revealed that plants produce this special molecule called sinapate esters. These molecules appear to block ultraviolet-B (UVB) sun rays from getting too far into the leaves where it may cause damage to the plant.
Whether or not sinapate esters may be incorporated somehow into today’s sunscreens for humans remains unsolved. This is something that we’re sure would cause a revolution in today’s sunscreen market.
