SHABBAT GUIDELINES All Shabbat powder cosmetics must be pre-scraped before Shabbat. Using a metal comb will keep the powder silky. All scraping must be a powdery consistency. You can only work from scrapings. All Shabbat cosmetics are to be applied with the appropriate brushes, using a separate brush for each color. Using Q-tips, fingers, or sponge applicators is not permissible. Each color needs its own brush, i.e., you may not use one brush to put on two different colors of eyeshadow. Mixing or blending of powders to produce a new color is not permitted before Shabbat or on Shabbat. The face and lips must be dry and free of color before applying the cosmetics on Shabbat. While it is permissible to place layer after layer of the same color during Shabbat, if one wants to use a different color, there cannot be any trace of the first color.
