Kylie filed a few trademark applications, all of which include skin moisturizers, cleansers, toners, facial scrubs, body scrubs, serums, masks, oils and so many more. She also filed another trademark for "Retail store services featuring skin care products, skin care preparation products, cosmetics, cosmetic preparations and gifts."
So yeah, it's totally happening.
It makes total sense for Kylie to take on skincare, with the success of Kylie Cosmetics, it was the natural next step for her.
