How to avoid sunburn

From Ask the Past:

“Take Deer’s Marrow, put it into a sufficient Quantity of Water with Wheat-Flour, and let them settle; then take some Ounces of what subsides to the Bottom and mix it well with a sufficient Quantity of the Whites of Eggs. Plaister your Face with the said Paste when you go to Bed at Night, and wash yourself the next Morning with warm Water. This Method is excellent to prevent Sunburn.”
