PRP skin regeneration therapy—injection alone or combined? Choose based on differences with PRF or laser combination

PRP skin regeneration therapy aims differently depending on whether you receive injection alone or combine it with needle treatment or laser. The method of injecting PRP for facial wrinkles and sagging (skin laxity) is rated as "weakly recommended" in the guidelines of the Japanese Society for Aesthetic Surgery[1]. For acne scars, reports indicate that adding PRP to laser shortens the duration of redness and swelling[2]. However, most research is small-scale, and preparation methods are not standardized[3][4].

What is the difference between PRP and PRF?

Both are made from your own blood, but PRF differs in that it contains fibrin, a component that clots easily. This fibrin is thought to form a network-like structure and gradually release growth factors, which are substances that promote skin repair.[5].

In a review of 7 studies on injected PRF involving 130 people, 4 studies examining facial rejuvenation reported moderate to marked improvement[5]. For smoothness and wrinkles around the eye area, PRF showed better results than PRP[5]. However, all studies included in the review had small sample sizes, and cannot be considered definitive comparisons.

One study injected 4 types of PRP and PRF made from a single blood draw into 20 people, administered 3 times at 4–6 week intervals[6]. Skin density and thickness improved, particularly in the lower eyelid area[6].

How does injection alone compare to combining it with needle-based treatment?

When combined with needle-based treatment such as microneedling, reports indicate additive results for acne scars[7]. In terms of visible improvement, post-treatment recovery time, and patient satisfaction, the combined approach performed better[7].

Research also shows that combining PRP with needle-based treatment resulted in less redness and swelling compared to needle-based treatment alone[3]. However, few studies have examined combination approaches, and many lack randomized comparison design[8].

What changes when you add laser?

The primary benefit of adding PRP to laser treatment is faster recovery. In research on acne scars using CO₂ laser, the side-effect duration was shorter on the PRP-added side, and downtime was also reduced.[2]The depth of scarring also improved more on the PRP-added side.[2].

It has been noted that PRP components may help reduce redness and pain after laser treatment.[9]Research on CO₂ laser combined with PRP also reported higher patient satisfaction compared to laser alone.[3].

Why do results vary more easily?

PRP is a treatment where results are difficult to standardize because the composition changes depending on how it is prepared and the individual. It has been pointed out that effectiveness varies depending on platelet concentration, preparation method, and the recipient's physical condition.[4].

A summary of 36 studies and 3,172 people using PRP for facial rejuvenation showed that most were observational studies without a comparison group.[3]Some studies did not clearly describe how PRP was prepared, making it impossible to aggregate and compare data.[3].

How should you choose based on your goal?

The guideline is to identify what you most want to change.

Fine lines around the eyes or skin firmness: PRP or PRF injections are the primary approach.[5][1]

Depressed acne scars: Microneedling or combination with laser are possible options.[7][2]

To shorten redness after laser: There is a concept of adding PRP to laser treatment.[2][9]

With injections, care is needed to avoid rare cases of accidental intravascular injection.[1]With any method, you should expect the possibility of bruising or redness.

What should be confirmed during consultation?

Which combination is right for you cannot be determined from an article alone. Whether it is fine lines, lack of firmness, or depressed acne scars is determined by examining your skin.

During your consultation, confirm which you will use—PRP or PRF—how it will be prepared, how many visits you plan to make, and the downtime for any combined treatments.
