The secret to clear, glowy skin? It’s inside you. Actually.

On Thursday, Page Six reported that “Ocean’s 8” stars Cate Blanchett and her pal Sandra Bullock had tried the “penis facial” with luxe NYC aesthetician Georgia Louise.

The $650 treatment is available in New York.

The Hollywood EGF Facial — a $650 treatment — involves a cleanse, chemical peel, microneedling, an “electrifying” face mask and a so-called “Epidermal Growth Factor (EGF)” — a serum that happens to be derived from the foreskin of Korean newborns. The substance supposedly helps generate collagen and elastin in the skin.

It’s just one of many borderline cannibalistic — and inevitably expensive — beauty products wooing the rich and vain these days.
