Celebrities are willing to do anything to look their very best.

For example, Kim Kardashian once said she would even eat feces if it would make her look younger.

It seems that Jennifer Aniston has been eating the exact same meal for the past 10 years.

On the other hand, Cate Blanchett takes the crown for the most unusual beauty hack.

In an interview with Vogue Australia, Cate Blanchett shared an interesting experience involving herself and Sandra Bullock. They had tried a distinct beauty treatment known as a "penis facial," which utilizes the foreskins of newborn Korean infants.

Blanchett explained: "Sandy [Sandra] Bullock and I saw this facialist in New York, Georgia Louise, and she gives what we call the penis facial and it's something."

"I don't know what it is, or whether it's just 'cause it smells a bit like sperm – there's some enzyme in it, so Sandy refers to it as the p**is facial."

The proper name for this procedure is an Epidermal Growth Factor facial (EGF). Ever since Blanchett mentioned her experience with it, social media has been buzzing with a mix of curiosity and astonishment.

"That is wrong on sooo many levels," says one person.

Another user asks: "This is a thing now?!"

While a third adds: "Made from the foreskin of a newborn Korean boy? Who looked at a foreskin of a baby and thought 'That should be on my face'?"

In response to the growing curiosity surrounding this treatment, Louise felt the need to provide a public clarification about what it entails.

During an interview with The Hollywood Reporter, she elaborated on the subject, stating: "The foreskin is collected during circumcision and the stem cells are then harvested and extracted through a centrifuge.

"I am always very mindful to explain radical serums and potions that I carry in my back bar, so I always explain that EGF is derived from the newborn baby f***skin, but cells were taken and from that, new cells are cloned from a laboratory."

Louise took to her Instagram page to share a separate statement, where she delves into the advantages of this treatment. She highlights that the cells used in the procedure can aid in the production of collagen and elastin, promote the healing of scar tissue, and contribute to the treatment of pigmentation and sun damage.

She pens: "EGF is derived from the progenitor cells of the human fibroblast taken way back when from donated stem cells from a Korean newborn baby foreskin."

"This cell was grown in a lab and I use only the clone EFG cells which are as potent as the original cell taken – which helps to generate collagen and elastin, heal scar tissue and help treat pigmentation and sun-damaged skins."

"FDA-approved stem cells and peptides are penetrated deep into the skin using a special electric micro-needling wand."

"This process allows the active ingredients to be transported deep in the skin by creating a temporary micro-channel."

If you find this treatment appealing, be ready to spend a significant amount of money, as it comes with a price tag of $650 (£511).

However, as an alternative option, you can purchase a Hollywood EGF home kit from the Georgia Louise website, which is available for $415.00 (£326).
