PRP for skin: what the evidence shows
PRP can modestly improve skin texture and, combined with microneedling, acne scars; it is not a wrinkle-filling or lifting treatment. In a 2018 randomised controlled trial, people rated their skin smoother on the PRP side, while masked dermatologists found no measurable difference from saline.[1][2]

What do people want from skin PRP?
People considering facial PRP may be looking for one of three changes: a fresher, more even tone; finer texture; or less tired-looking skin under the eyes. In Seoul, PRP is also offered alongside microneedling or lasers. PRP works through signals released by platelets rather than by filling space, so the change it brings is gradual and subtle.
Does PRP improve facial texture and wrinkles?
A 2018 randomised trial in Chicago tested this directly. Each participant had 3 mL of PRP injected into one cheek and saline into the other, without knowing which was which. Two dermatologists who also did not know the sides scored fine lines, pigment, roughness and sallowness. Their scores showed no significant difference between PRP and saline. Six months after the single treatment, however, participants rated the PRP side as more improved for texture (2.00 vs 1.21 on a 5-point scale) and wrinkles (1.74 vs 1.21).[1]
Wider reviews point the same way. An overview of 13 systematic reviews, based on 28 primary studies of which 18 had no control group, rated confidence in the findings as low or critically low for 12 of the 13 reviews and found the evidence insufficient for firm conclusions.[3] A 2025 review analysed 20 PRP and PRF studies with 514 patients together and counted how often each skin feature improved: significant gains were reported in 80% of studies on skin thickness, 75% on elasticity, 40% on wrinkles, 33% on texture, 17% on uneven pigment and none on hydration. No serious adverse events were reported.[4]
Does PRP help acne scars?
For atrophic (depressed) acne scars, PRP works as an add-on to microneedling. A meta-analysis of 4 randomised and 10 split-face controlled studies with 472 patients found that adding PRP to microneedling roughly tripled the odds of more than 50% improvement on a standard scar scale (odds ratio 2.97) and raised patient satisfaction, without more severe redness or swelling.[2] The needling does the structural work; PRP appears to support the healing response.
Can PRP treat dark circles and under-eye texture?
Under-eye darkness has several causes: extra pigment, visible blood vessels, thin skin and hollowing. PRP helps some of these more than others. A 2025 systematic review of 14 studies found that PRP had the stronger evidence for pigmentation, while PRF (a related fibrin-rich preparation) was linked with better texture, fine lines and crepiness. PRF gains often faded by six months, whereas PRP results for pigment held at similar intervals. Neither was shown to be superior.[5]
A deep tear trough is a volume problem, and PRP is not a filler. If hollowing is the main cause, the doctor may discuss volume-based options instead.
Which skin goals suit PRP?
| Goal | Role of PRP | Options often discussed alongside |
|---|---|---|
| Dull, uneven skin | Possible modest change over a course | Skin boosters, laser toning, daily sunscreen |
| Fine texture and pores | Mixed results on its own | Microneedling, fractional lasers |
| Atrophic acne scars | Useful add-on to microneedling | Subcision, fractional lasers |
| Under-eye pigment and crepiness | Some benefit in small studies | PRF, topical creams, lasers |
| Hollows and volume loss | Not a volume treatment | Fillers or other volume options |
| Sagging skin | No lifting effect | Ultrasound or radiofrequency lifting |
Who is a good candidate for skin PRP?
PRP suits people who prefer a treatment made from their own blood, who are happy with gradual, modest change and who can return for several sessions. It suits less well anyone hoping for a visible change before an event next week, or for lifting and volume. If you take blood thinners or regular painkillers, read what to stop and what never to stop before booking. For how PRP compares with product-based injections, see PRP vs skin boosters.
How soon will I see a change after skin PRP?
Redness and small bumps may settle quickly, but swelling or bruising can last longer, especially when microneedling is added; in one trial, all local reactions had resolved within two weeks.[1] Any texture change builds over the following weeks, so judge the result a month or more after a session, using photos taken in the same light.
Is skin PRP better as injections or with microneedling?
For acne scars, studies support adding PRP to microneedling rather than microneedling alone.[2] That does not show whether it beats PRP injections alone, and for general texture both methods are used.
Is skin PRP safe?
The usual reactions are redness, swelling and bruising at the injection points, which come from the needle rather than the plasma.[1] The rare serious risk is an injection into a blood vessel, which is why facial PRP belongs in a doctor-led clinic.[6]
