Short answer first: these are not two versions of the same treatment. PRP is made from a small sample of your own blood, prepared and injected in the same visit, and it has modest but real clinical evidence for skin quality and for hair thinning. Exosome products are different. There are no FDA approved exosome products, and the FDA has issued a public safety notification about serious adverse events in patients treated with unapproved products marketed as containing exosomes. If a clinic offers you injected exosomes today, that is not an upgrade over PRP. It is an unapproved biologic.
What PRP actually is
PRP stands for platelet rich plasma. We draw a small amount of your blood, spin it in a centrifuge to concentrate the platelets, then inject that concentrate or apply it during microneedling into your own skin or scalp. Platelets carry growth factors that your body already uses for tissue repair. The concept is to concentrate that repair signal where you want it.
Because the material comes from you and goes back into you in the same sitting, the safety profile is reasonable. The trade off is that PRP is not standardized. Different kits, spin speeds and injection depths produce genuinely different products, which is a large part of why the research is so mixed.
What the PRP research shows
For skin, a 2025 meta-analysis of nine randomized trials covering 358 patients found PRP improved both patient satisfaction and objective measures of skin aging compared with controls, with no significant difference in adverse effects. The authors were direct about the weaknesses: few studies, small samples, short follow up, and no standard way of measuring results between them. An earlier systematic review of PRP in facial rejuvenation landed in a similar place, with encouraging outcomes and wide variation in protocol.
For hair, the evidence is a little stronger and still not strong. Meta-analyses in androgenetic alopecia report increased hair density after PRP compared with placebo, and adding PRP to topical minoxidil outperforms minoxidil alone, though the authors graded that certainty as low to very low. A separate meta-analysis of PRP in androgenic alopecia reached the same general conclusion, with adverse reactions uncommon and none serious.
One honest note that most clinic pages omit. The centrifuges and kits used to make PRP are cleared as medical devices, usually for narrow surgical indications. Using PRP on the face or scalp is off label. Off label use is legal and routine across medicine, but it is not the same thing as FDA approved for that purpose, and you deserve to hear the difference.
What exosomes are
Exosomes are tiny membrane bound vesicles that cells release to signal each other, carrying proteins and genetic material. In aesthetics they are usually derived from cultured stem cells, from birth tissue such as amniotic or umbilical products, or from plants. They are injected, applied after microneedling, or added to a facial.
The biology is genuinely interesting. Laboratory and early human work suggests exosomes can influence collagen production, pigmentation and wound healing. That is why the field is worth watching. It is not why you should buy it this year.
The regulatory reality, which is the part that gets skipped
The FDA is unambiguous. There are currently no FDA approved exosome products. Exosomes used to treat diseases or conditions in humans are regulated as drugs and biological products, subject to premarket review. The 2019 notification also states that some clinics claim these products fall outside those rules, and the FDA calls that claim simply untrue. Enforcement has continued since, including a December 2024 warning letter to a company marketing an exosome product as an unapproved new drug and unlicensed biologic. The FDA also maintains a broader consumer alert on regenerative medicine products.
The published evidence matches that caution. A 2024 systematic review of topical exosome and peptide therapies found nine eligible exosome studies, reported encouraging signals for collagen deposition and wound healing, and stated plainly that none of the exosome therapies it reviewed were FDA approved or being studied under an FDA authorized clinical trial. Promising is not the same as proven, and neither is the same as legal to sell as a treatment.
Topical exosomes after microneedling
This is often presented as the safe middle ground, since a serum is not an injection. Be careful with that logic. Microneedling opens thousands of channels in the skin, so anything applied afterward is not behaving like an ordinary cosmetic. Sterility, sourcing and manufacturing quality matter more, not less. Labelling a product as a cosmetic does not change what it is if it is being used to alter the structure or function of your skin.
Red flags that mean see a clinician, not a booking page
- Fever, spreading redness, worsening pain or drainage after any injection or microneedling session
- Any change in vision after a facial injection. That is an emergency, go to the emergency room
- Hair shedding alongside fatigue, weight change, irregular or heavy periods, or cold intolerance. Get thyroid, ferritin and hormone labs before buying a hair treatment
- A new, changing, bleeding or non healing skin lesion. That needs evaluation, not a cosmetic procedure
- Pregnancy or breastfeeding, active skin infection, bleeding disorders or blood thinners. All need a conversation first
What to ask before you book anything
Ask whether the product is FDA approved for what is being treated. For exosomes in 2026, the honest answer is no. If a clinic says it is part of a study, the FDA advises asking for the Investigational New Drug number and the agency’s letter acknowledging it. For PRP, ask who prepares it, which device is used, how many treatments the plan includes, and how results will be measured at follow up.
The bottom line
If you want a treatment with published human evidence and a sensible safety profile, PRP is the more defensible choice today, with realistic expectations of gradual, modest improvement rather than transformation. If you want the newest thing on the market, understand that with exosomes you are the trial, without the protections a trial provides.
