Sunscreen use could lead to better blood vessel health, study suggests

(FASTNEWS|COLOMBO) – Washington D.C [U.S.A], Apr 7 : Sunscreen protects the skin’s blood vessel function from harmful ultraviolet radiation (UVR) exposure by protecting dilation of the blood vessels. Perspiration on the skin may also provide protection to the skin’s blood vessels from sun damage, a recent study has suggested.


UVR from the sun has been well-documented as a contributing factor to skin cancer and premature skin aging. UVR has also been found to reduce nitric oxide-associated dilation of skin blood vessels (vasodilation) by reducing the amount of nitric oxide available in the skin. Nitric oxide is a compound essential for blood vessel health. Vasodilation of the skin’s blood vessels plays an important role in regulating body temperature and responding to heat stress, both locally in the skin and throughout the body.

The findings were discussed in the Experimental Biology 2019 meeting.
