In the days following Kylie Jenner’s announcement that she’s pivoting into skincare from makeup, the beauty mogul has gained a lot of traction in the press. Some of that press isn’t good though, as one product in particular has both the blogosphere and social media in a frenzy. The line’s Walnut Face Scrub is raising concern over whether the ingredients list is safe enough to be used on the most fragile parts of the skin. Of course, it’s up to consumers to decide whether or not the product is right for them, but there is one key ingredient that could prove to be far too harsh to be used in a facial product.

Kylie Skin

The six-product line promises to deliver skincare in cute, simple packaging. It doesn’t stray from the affordable price range Kylie’s cosmetics lines are known for, either. All of the products in the line so far will retail below $3o. The line ranges from things like a foaming facial cleanser to a vitamin C serum, and most products are below $25. Kylie, who has been candid in the past about using spa treatments and cosmetic procedures, is the face of the brand. This should be a red flag to consumers in the first place, as it would be unfair to advertise the billionaire celebrity’s skin as being achieved solely through this line.

Many fans are excited for the products, nevertheless. The skincare line’s instagram account has garnered over one million followers in less than a week, and that’s before its May 22 launch date. What many are excited about, though, is the idea that an entire skin regimen can be purchased for just $125. A single skincare product from Sephora can cost that much—or more—so the affordable line may be the perfect intro into skincare for those who don’t know where to start. The line also promises to deliver cruelty-free, vegan, gluten free products that are also free from sulfates and parabens (which may not actually be that bad). For such a low price, it’s hard to find anything wrong with the line.

The 411 On Walnut

Wrong, that is, except for just one thing—walnut powder is really bad for your skin! The ingredient is far too harsh to be used on the face. It’s even been known to cause micro tears in the skin, which will leave your face looking a lot older than it is. Since the multi-billion dollar skincare industry is all about looking young, dewy, and glowing, a product that causes microscopic abrasions and can increase the signs of aging is just—not the look. Jenner, however, has been slinging the product as if it’s not the same as that god awful apricot scrub we all started using in fifth grade.

“Some walnut scrubs are super harsh…” says Jenner in an ad for the walnut face scrub on Twitter. Clearly Jenner knew that the scrub was going to cause controversy if she and her team felt the need to address it before it even launched in an ad campaign for the product. Audiences, however, are not convinced that the product is truly as gentle as it promises. Skincare lovers are better off using a chemical exfoliant such as a lactic acid instead of a harsh physical exfoliant.

We’re not stupid enough to believe that Kendall Jenner’s skin is glowing because of Proactiv, and we’re definitely not stupid enough to believe that Kylie Jenner uses a face scrub that will scratch your skin off.
