Hailey Bieber is famous for glowing skin, so plenty of people assumed Botox was part of her routine. On a podcast in late 2025, she said it isn't — at least not in her face. What she uses instead comes from her own blood.
What Hailey Bieber said
On Owen Thiele's podcast In Your Dreams (October 2025), she said: “I made a commitment to myself that I wasn't going to do any Botox until I was in my 30s.” The only Botox she gets is in her jaw, to ease TMJ (jaw joint) pain.
Instead, she talked about PRP and PRF: “I like to do things that I can trust is from your own body,” adding that she has them “a couple times a year.”
What is PRP?
PRP (platelet-rich plasma) is made from a small sample of your blood. An anticoagulant keeps the blood from clotting, and a centrifuge spins it to separate a plasma layer packed with platelets.
- Platelets carry growth factors that play a role in tissue repair and collagen production.
- PRP releases them quickly after treatment: a short, strong boost.
- It's injected into the skin or applied during microneedling.
What is PRF?
PRF (platelet-rich fibrin) is a newer variation. The blood is spun without anticoagulant, so it forms a soft fibrin gel that holds platelets and white blood cells.
- The fibrin releases growth factors slowly, over days rather than hours.
- The injectable form, often called i-PRF, is popular for the delicate under-eye area.
PRP vs PRF at a glance
| PRP | PRF | |
|---|---|---|
| Anticoagulant | Yes | No |
| Growth factor release | Fast | Slow and steady |
| Often chosen for | Pigmentation, thinning hair, microneedling | Texture, fine lines, under-eyes |
Where it's used
- Under the eyes — crepey skin and fine lines, often with PRF.
- Overall skin quality — texture, dullness and fine lines, injected or with microneedling.
- Acne scars — usually PRP combined with microneedling or laser.
- Thinning hair — PRP injected into the scalp is one of its most common uses.
What the evidence says
- Because both come from your own blood, allergic reactions are unlikely — a big part of the appeal.
- A systematic review of under-eye studies found PRF more often improved texture and fine lines, and PRP did better for pigmentation, with no clear overall winner.
- Results build gradually, and most studies are still small. In some under-eye studies, PRF's improvements had faded by about six months, which is why clinics suggest maintenance sessions.
- Neither is a Botox swap: they don't relax muscles, so expression lines won't soften the same way.
Thinking of trying it in Korea?
PRP and PRF are widely offered at Korean dermatology clinics, often combined with microneedling or laser. Part 2 covers price, sessions and downtime in Korea.
