1  Snooki’s Cat-Litter Face Scrub

“Jersey Shore” alum Snooki was on a mission to find a spa-quality DIY facial on the cheap when she stumbled upon an unconventional exfoliant. “Well, I definitely like to Google a lot, and I don’t like to spend a lot of money on spa treatments,” she explains on “Conan.” “So I Googled what else I could use that was not so expensive. It was cat litter.”

So is cat litter safe to rub on your face? Los Angeles-based licensed aesthetician Gregory Dylan advises against it. “Yes, it will exfoliate, but it’s going to be much too rough on the face, way too sharp and jagged. It could create micro-tears and scratches in the skin,” he says. “In a pinch or for a quick home treatment, one can sprinkle some baking soda into their regular cleanser for added exfoliation.”

2 Cate Blanchett’s “Penis Facial”

When Cate Blanchett told Vogue Australia that she and “Ocean’s 8” co-star Sandra Bullock got “penis facials,” most people were understandably confused. According to celebrity facialist Georgia Louise’s website, the treatment (officially known as an epidermal growth factor, or EGF, treatment) utilizes FDA-approved “progenitor cells of the human fibroblast taken from Korean newborn baby foreskin” — cells that help generate collagen and elastin. Sounds cringe-y, but Louise has clarified that the cells she uses in her treatment are actually clones of cells provided by a Korean stem cell bank — no babies are used!

The cost will set you back $834, but if just then thought of human byproducts makes you feel icky, licensed aesthetician Gregory Dylan tells LIVESTRONG.COM that you can get a facial that uses synthetic EGF for similar benefits.

3  Kim Kardashian’s “Vampire Facial”

If you feel faint at the sight of blood, you might want to avoid watching the infamous “Kim and Kourtney Take Miami” episode where Kim Kardashian gets a “blood facial” — a treatment that involves harvesting your blood, using a centrifuge to extract its platelet-rich plasma (PRP) and then injecting it into your skin with needles. No big deal.

“With microneedling, the skin is essentially repairing itself thanks to a ‘controlled injury,’” Dylan says. “This helps to improve the appearance of scars, sun spots and wrinkles.” He says PRP is rich in “growth factors,” which induce extra collagen and new cells into the skin by penetrating it with a microneedle. If you’re squeamish, you can try a treatment using silicone nano-tips, which only penetrate the surface of the skin, that uses a synthetic epidermal growth factor serum (EGF), for a less intense but similar effect. You can get this treatment, also known as nano-infusion or microchanneling, by request with most clinical aestheticians.

6 Margot Robbie’s Unconventional Nipple-Cream Usage

Like many of us, Margot Robbie won’t go anywhere without her lip balm — or at least her version of it. Turns out, to moisturize her pout, Robbie prefers to use a serum that's secretly revered by breastfeeding moms — Bepanthen, aka nipple cream. “I have a conspiracy theory that lip balms actually have additives in them to dry your lips out so you keep buying them,” the “I, Tonya” actress tells Elle UK. “But because Bepanthen is just a cream for dry skin, it works.”

According to licensed aesthetician Gregory Dylan, the appeal of nipple cream probably comes from its soothing texture. “It’s probably going to penetrate a little bit better and still provide a really nice softening effect,” he said. If Robbie’s conspiracy theory got to you, but you’re not loving the idea of nipple cream, Dylan recommends opting for petroleum jelly for “a nice, conditioning and moisturizing effect.”

7  Miranda Kerr’s Leech Facial

We would do anything to get skin like Miranda Kerr’s, and, apparently, so would she. “I’ve had a leech facial,” the supermodel confessed at a conference hosted by Gwyneth Paltrow’s wellness website, Goop. “I kept the leeches, they’re in my koi pond. You’re not allowed to reuse them, and if you don’t take them home then she kills them, and I didn’t like that idea.”

Technically speaking, putting leeches on your face might have some benefits: “What the leeches do is suck and bring the blood to the surface, and the blood carries nutrients and oxygen to the skin,” Dylan says. “So, yes, technically it would give a benefit to the skin, however, it just sounds a little gross.”

8  Scarlett Johansson’s Apple Cider Vinegar Cleanser

Although the powers of apple cider vinegar for your metabolism and microbiome have been vastly overestimated, Scarlett Johansson touted some of its lesser-known properties. “It’s a nice way to treat your skin if you don’t want to use all those harsh chemicals that a dermatologist would recommend,” she told Elle UK.

According to Dylan, apple cider vinegar contains alpha hydroxy acids (AHAs) which act like an astringent on your face — tightening and reducing the appearance of pores. “Alone, [apple cider vinegar] could potentially be too acidic for a lot of skin types and potentially cause a bit of irritation,” he says. On the other hand, store-bought toners contain “ingredients that are going to help soothe and calm it as well as having that nice, tightening, astringent benefit too.” So if you have sensitive skin, avoid this $8 grocery-aisle remedy and opt for a store-bought toner instead.
