|Hans Adam Weissenkircher, Helios on His Chariot, c. 1685|
"To keep the face from Sunburn, you had best wash with water drawn from the whites of eggs, or juice of soure grapes... or take goats suet well washed in cleare water, beat it in a mortar with rose water, strein it through a thick cloth, then take oile of sweet almonds one ounce, sugar candy two drams, camfre half a dram, boile them all together, stirring them continually that they may be white, when it hath boiled a pretty while put it into a glass for your use. If you goe abroad in the Sun or Wind anoint the face with it, and 'twill preserve your complexion."
