KATE Protection Expert Lasting (also called KATE Protection EX Lasting) is a mattifying Japanese makeup base milk. The milky fuid creates a smooth, matte surface for makeup application and controls shine. It protects against UV rays and dryness while preventing airborne pollutants from clinging to skin. Ideally suited for women in their late teens to early 20s, it mattifies, smoothes, and protects skin without a heavy look or feel to keep makeup looking just-applied longer.
