The walnut scrub from her new line, Kylie Skin, is facing criticism and receiving backlash from fans.
She claims it's her "secret to a fresh face," but not everyone is convinced.
Some people are slamming the product, saying walnut shells can be abrasive and cause micro-tears on the skin.
Nonetheless, Kylie claims the product is safe for everyday use, and she uses it two to three times a week.
The new line launches on May 22.
