Actress Kate Beckinsale loves PRP

Kate Beckinsale is ready to set the record straight about her flawless-looking skin: It's not because of Botox. "I haven’t had any!" the English actress told the Sunday Times in an interview about her upcoming film Jolt. "I’m not against people having it. [But] I do get pissed off. It’s sort of a given that I’ve had it, which I just literally haven’t. I’m frightened of paralyzing my face."

The 47-year-old credits her youthful glow, in part, to genetics. "My mum wouldn’t even get a facial, she is suspicious of anything like that, and looks f***ing radiant and amazing," she said. But the other part is a regular treatment that she does endorse, a type of procedure known as platelet-rich plasma (PRP) therapy. "I do like PRP, when they take your blood [plasma and reinject it into your skin]. That’s a real thing, from your own body. But not with scary poisonous things!” she told the Sunday Times.

So what is PRP, and should people be considering it over Botox? Yahoo Life spoke with several dermatologists to get the answers. Here's what you need to know.

The procedure involves getting blood drawn, spun around and then reinjected into the face

"PRP for the face is typically combined with microneedling," says Dr. Norman Rowe, a board-certified plastic surgeon in New York. Microneedling, according to Yale Medicine, is a process by which tiny needles are used to create small punctures where serums — or in this case, blood — can penetrate under the skin. Rowe says that after getting blood drawn, the sample is "put into a centrifuge to separate the platelet-rich plasma [PRP] from the rest of the components of the blood."

Dr. Dustin Portela, a board-certified dermatologist who runs a popular TikTokaccount with more than 1 million followers, elaborates on what this means. "As the centrifuge spins the tubes, the red blood cells and white blood cells separate from the platelets and the plasma in the blood," says Portela. "The platelets and plasma can then be drawn out of the tube and used for healing or cosmetic purposes."

Experts say to think of the plasma-rich protein as a "magical, rejuvenating serum". Dr. Mona Gohara, associate clinical professor of dermatology at Yale School of Medicine, says what's left after the centrifuge is very powerful. "This magical, rejuvenating serum, derived from Mother Nature, is driven into the skin with small microneedles, which themselves create collagen by causing tiny trauma to the skin," says Gohara.

Collagen, a protein found throughout the body, is a part of what determines the skin's elasticity. Rowe says it's not the only thing that PRP may stimulate. "PRP can help with the production of collagen and elastin, the building blocks of skin," he says.
