For those with rosacea, ultraviolet damage as well as heat from the sun are the two factors to consider when choosing a sunscreen.

You'll find more information at www.RosaceaGuide.ca My favourite screens are Anthelios 45 and the Ombrelle line. Be sure you like the feel of the sunscreen you choose, so that you will actually use it. Richard Thomas
