When stunner Raquel Welch blasted onto our TV screens in the 1966 film Fantastic Voyage, she was only 25 years old. Today, the 76-year-old still retains that youthful glow without the help of cosmetic surgery.

While promoting her new film How to be a Latin Lover, the ageless beauty was glowing. Her secret? Udder cream. Yes, you read that right—udder cream. The balm farmers use to ensure their cows don’t have dry, cracked teats is now being used to moisturize women’s faces. Who would have guessed it would now be a holy-grail age-defying beauty product.

According to Welch, “[Udder cream is] something you can put on overnight and when you wake up you don’t have a dry, cracking mouth. Believe me, there are a lot of mummies walking around with Bag Balm (one brand of udder cream).

Cosmetic dermatologist Dr. Sam Bunting told the Daily Mail that Bag Balm is essentially “souped-up Vaseline.” Like Vaseline, one of Bag Balm’s main ingredients is petroleum jelly. However, Bag Balm features the addition of 8-hydroxyquinoline sulfate, an antiseptic which gives the added benefit of warding off infections.

Not only is Bag Balm said to erase wrinkles but it also can be used to treat diaper rash, chafing, weak, breakable nails, and dull hair, advocates say. Talk about a miracle product!

Given how sticky and oily Vaseline is, we’re not sure about adding Bag Balm to our morning routines. “The formulation is useful to encourage healing of small abrasions and irritations,” Dr. Bunting said before echoing our hesitance to use Bag Balm daily. “I’d imagine, however, that for most it wouldn’t be elegant enough for regular facial use.”
