Real Housewives of New York City alum, author and entrepreneur, Bethenny Frankel, has made a name for herself on TikTok as one of the app's toughest critics. 

In one of Frankel's most recent reviews, the Shark Tank host and founder/CEO of Skinnygirl picked apart Kim Kardashian's new skincare line: SKKN by Kim. 

The video began with the 51-year-old introducing the products she sampled from the line; the SKKN Exfoliator (MSRP of $55) and the SKKN Eye Cream (which offers 0.5 oz of product of $75).

Frankel also told viewers that she specifically chose these two items (out of the total of nine in the line) for her review because she's very familiar with this category of skincare and felt knowledgeable enough to speak on it. 

"Any line that makes it seem like you have to do all of the steps [to achieve results] is just doing a smash-and-grab job, because your skin is different everyday," she explained as she unpackaged the products. 

"The packaging...is impractical at best," Frankel huffed as her fingers grazed over the globe-shaped container. 

"It's bulbous, I don't understand it–it doesn't stack, I don't have a circular house or medicine cabinet, it doesn't even have a flat bottom; so it's effectively like an egg," she mocked. 

Her thoughts on the exfoliator's packaging weren't any better: "This is crazy, it's gigantic!" 

"You have to be a billionaire to use this product because if you don't have a private plane, how are you traveling with this? It's just not practical–and I'm a very practical and organized person–which just shocks me because don't the Kardashians organize their jelly beans by color?"

Before Frankel is able to use the products, she fumbled with the exfoliator and made a witty rebuttal. 

"Kim Kardashian is the only person who could open up a Rubik's Cube and make it skincare."

She then went on to compare the texture of the luxury exfoliator to the nostalgic acne solution, Proactiv, which can be found at almost any drugstore for nearly half the price—and whose spokesperson at one time was Kim's youngest sis, Kylie—noting that at least this one smelled good.

"It has a little bit of a fragrance–no problem–and it's got those micro white granules, we've seen them before; I think it was Proactiv." 

She continued: "I like that form of exfoliating, is it worth the money they're charging? Unlikely." 

And as far as the eye cream, she said: "It's like a melted butter consistency, but not, like, ultra rich." 

"I feel like, for this price tag it would [have to] be Chantecaille, Sicily, rich–it's not Kardashian rich. Richer than I am, maybe, but not Kardashian rich," she joked as she smeared the cream into her face. 

While the honest review may have come off as abasing, Frankel said that overall, she liked the products. 

"This is definietly good skincare, this is quality; I just think it's extremely impractical in its packaging. I know that it's very ecologically sound and a good quality product–that's likely somewhat overpriced."

An issue that's apparently not unique to the Kardashian's line of products. 

"But most beauty is overpriced," Frankel argued.
