If you have researched regenerative treatments for skin or hair, you have probably run into two terms that get used almost interchangeably: exosomes and PRP. They are not the same thing. So what are exosomes, exactly, and how is exosome therapy different from platelet-rich plasma? Below is a plain, physician-led explanation of what each treatment is, how they compare, and what the current regulatory status actually means for patients considering either one.
What to Know
- Exosomes are microscopic particles released by cells that carry proteins, growth factors, and genetic signals used in cell-to-cell communication.
- PRP (platelet-rich plasma) is made from a patient’s own blood, drawn and processed in-office. Exosome products come from a separate cell source, not from the patient’s own blood.
- Exosome products used in aesthetics are not FDA-approved for cosmetic or therapeutic use. The FDA has issued a public safety notification about unapproved exosome products.
- Both exosomes and PRP are studied for skin quality, texture, and hair thinning, but neither is a treatment or cure for any medical condition, and results vary by patient.
- Candidacy for either treatment is a physician decision made at consultation, not a self-selected choice.
- At Bespoke Aesthetics, this work is overseen by Dr. Carolyn Indianos, MD, a physician and the practice’s Founder and Medical Director.
What Are Exosomes?
Exosomes are tiny, membrane-bound particles released by cells. Think of them as message carriers: they hold proteins, growth factors, and RNA fragments and pass that cargo between cells, which is part of how cells communicate and coordinate repair activity in the body. Exosomes are naturally occurring, but the exosomes used in aesthetic and wellness settings are lab-processed products, typically derived from a cell source separate from the patient, not extracted from the patient’s own blood or tissue during the visit.
Interest in exosomes has grown quickly because early research suggests they may play a role in supporting the skin’s own repair signaling and in stimulating hair follicles. That research is still developing. Exosome therapy is an active area of scientific study, not an established, standardized treatment with settled long-term outcome data.
How Exosome Therapy Works
In a clinical setting, an exosome product is typically applied topically or introduced into the skin, often paired with microneedling so the product can reach a deeper layer of the skin than a surface application alone would allow. The idea behind the pairing is straightforward: microneedling creates controlled micro-channels, and the exosome product is applied during that window. What the exosomes do once introduced, and how consistently, is still being studied. No aesthetic practice can promise a specific biological result from exosome application, and any practice that does should raise a red flag.
Exosomes vs PRP: What Actually Separates Them
This is the question most patients are really asking. Exosomes and PRP get grouped together because both are regenerative-category treatments often delivered alongside microneedling, and both are discussed in the context of skin quality and hair thinning. The source and mechanism are different.
PRP is made from a patient’s own blood. A small blood draw is taken in-office, spun in a centrifuge to concentrate the platelets, and that concentrated plasma is then applied to the treatment area, usually with microneedling with PRP. Because PRP comes from the patient’s own body, it does not carry the same sourcing and regulatory questions that exosome products currently do.
Exosome products are not derived from the patient in the room. They come from a separate cell source processed by a manufacturer, which is precisely why the FDA has flagged this category for oversight. Neither treatment is proven superior to the other for every patient or every goal. They are different tools, evaluated differently, and a physician determines which one, if either, fits a given patient’s history and goals.
Exosomes for the Face
Most of the current interest in exosome facials centers on skin quality: texture, tone, and the overall look of tired or dull skin. An exosome facial generally pairs a topical or microneedled exosome application with the skin’s own healing response during the days that follow. As with any treatment in this category, results vary by individual, and no outcome is guaranteed. A consultation with a physician is the appropriate way to evaluate whether an exosome facial fits a patient’s skin goals and history, rather than treating it as an off-the-shelf, one-size-fits-all service.
Exosome Hair Restoration
Exosomes are also discussed in the context of hair thinning, usually delivered via microneedling to the scalp in a manner similar to PRP hair treatments. The premise is that the growth factors and signaling molecules in the product may support the hair follicle environment. This is an area of ongoing research, and exosome hair restoration is not a guaranteed regrowth treatment and is not a treatment for any diagnosed medical hair loss condition. Anyone considering it for hair thinning should have a physician evaluate the underlying cause of the hair loss first, since not every case of thinning responds to the same intervention.
What a Session Involves
Every treatment plan starts with a consultation. A physician at Bespoke Aesthetics reviews health history, current medications, and treatment goals before recommending PRP, an exosome-based option, or another approach entirely. If PRP is selected, the visit includes a blood draw and processing time before application. If an exosome product is being considered, the physician will discuss the product’s sourcing and current regulatory status directly with the patient as part of informed consent, since this is not an FDA-approved use. Most sessions in this category, whether facial or scalp-focused, run under an hour and are frequently paired with microneedling.
Regulatory Status: What You Should Know
This is the part of the conversation that gets skipped by practices trying to sell exosome treatments as the newest, most advanced option available. It should not be skipped. Exosome products marketed for aesthetic or therapeutic use are not FDA-approved. The FDA has issued a public safety notification on exosome products, including reports of adverse events tied to certain products on the market. That does not mean every exosome product or every provider is unsafe. It means the category lacks the standardized approval, manufacturing oversight, and outcome data that FDA-approved treatments carry, and patients deserve to know that before they book anything, not after. A physician-led practice should be willing to say this plainly and let the patient decide with full information, rather than glossing over it in marketing copy.

Frequently Asked Questions
What are exosomes used for in aesthetics?
Exosomes are studied for their potential role in skin quality, texture, and hair thinning support, typically delivered with microneedling. They are not an approved treatment for any medical condition, and outcomes vary by patient.
Are exosomes better than PRP?
Neither is proven superior to the other. They come from different sources (exosomes from a separate cell source, PRP from the patient’s own blood) and work through different mechanisms. A physician evaluates which option, if either, fits a specific patient’s goals and history.
Are exosome treatments FDA-approved?
No. Exosome products marketed for aesthetic or therapeutic use are not FDA-approved. The FDA has issued a public safety notification on unapproved exosome products, and any practice offering them should discuss this openly as part of informed consent.
Do exosomes work for hair loss?
Exosome hair restoration is an area of active research, not a guaranteed regrowth treatment, and the cause of hair thinning should be diagnosed by a physician before any approach is recommended.
Is there downtime after an exosome facial or PRP treatment?
Both are generally low-downtime, similar to recovery after microneedling alone. Individual recovery varies, and a physician can outline what to expect based on the specific treatment and technique used.
