Kylie Jenner and Caitlyn Jenner are in the middle of a bitter feud

According to the United States Patent and Trademark Office database, Kylie Cosmetics registered three trademarks with the federal agency on September 27 that appear to be for a new skin-care line. Two of the applications — “Kylie Skin” and “Kylie Skin by Kylie Jenner” — are for goods, which according to the filing could include moisturizers, scrubs, serums, masks, and so forth. The third filing — another “Kylie Skin” — is for retail store services, which can mean the pop-up stores that she and her sister Kim Kardashian have previously launched for their makeup collections.
