What Are Exosomes?

Exosomes are 30–150 nanometer extracellular vesicles produced by mesenchymal stem cells (MSCs). They function as the cell’s signaling cargo — carrying growth factors (TGF-β, VEGF, FGF), cytokines, lipids, mRNA, and microRNA that modulate inflammation, stimulate fibroblast activity, and orchestrate tissue regeneration. Unlike whole stem cells, exosomes carry the regenerative signal without the cellular material, which means a more consistent product, no immune rejection risk, and easier sterile handling.

How Bespoke Sources Exosomes

Sourcing matters more in regenerative medicine than almost any other treatment category. Bespoke uses exosome products from FDA-registered, AATB-accredited tissue banks with full chain-of-custody documentation. The products we use are isolated from screened donor MSCs, processed under cGMP standards, and shipped under cold chain. We do not use research-grade, undisclosed-source, or imported products.

Dr. Indianos personally reviews each lot certificate of analysis before use.

What We Treat with Exosomes

Bespoke uses exosome therapy for three primary clinical indications:

1. Facial Skin Rejuvenation

Combined with microneedling or RF microneedling, exosomes drive a faster, smoother resurfacing recovery and amplified collagen response. Targets fine lines, post-acne texture, hyperpigmentation, and overall skin quality. Most patients book a series of 3 sessions spaced 4–6 weeks apart.

2. Scalp & Hair Restoration

Microchanneling or scalp microneedling with exosome application stimulates dormant hair follicles via growth-factor signaling. Indicated for early-to-mid androgenic thinning, telogen effluvium, and as an adjunct to oral or topical regimens. Typical protocol: 3 sessions, 4 weeks apart, then maintenance.

3. Post-Procedure Recovery

Topical exosomes work well after microneedling, RF, biostimulator injections (Sculptra, Radiesse), or laser. They shorten visible recovery time. They calm post-treatment inflammation. And they support the healing response.

Exosomes vs. PRP — What’s the Difference?

PRP (platelet-rich plasma) and exosomes both deliver growth factors, but they come from different biological sources and behave differently:

• PRP is autologous — concentrated from your own blood. Growth-factor content depends on your physiology, age, nutrition, and that day’s draw.
• Exosomes come from young, healthy donor MSCs — standardized concentration, no donor-day variability.
• For patients over 50 or those with depleted regenerative reserves, exosomes often outperform PRP on outcome consistency.
• For younger patients or those who prefer fully autologous treatment, PRP remains an excellent choice.
• Both can be combined with microneedling. Bespoke also offers microneedling with PRP for patients who prefer that route.

Bespoke’s Exosome Protocol

Standard treatment-day workflow:

1. Topical anesthetic applied for 20–30 minutes
2. Microneedling, microchanneling, or RF treatment per indication
3. Exosome serum applied directly to treated tissue while channels are open
4. Post-treatment occlusive recovery sheet for 60 minutes
5. Take-home recovery skincare provided

Total chair time: 60–75 minutes. Visible improvement begins at 2–4 weeks; collagen-mediated remodeling continues for 12–16 weeks per session.

Who Is a Candidate?

Exosome therapy is appropriate for adults seeking regenerative skin or scalp results who:

• Are not pregnant or breastfeeding
• Have no active malignancy or autoimmune flare
• Have no acute skin infection at the treatment site
• Can tolerate microneedling-style discomfort with topical anesthesia

Regulatory Note

Exosome products in the U.S. are not currently FDA-approved as drug therapies; they are regulated as Section 361 human cellular/tissue products under specific tissue-bank guidelines. Bespoke uses only products from FDA-registered, AATB-accredited tissue banks. We discuss the regulatory status, evidence base, and realistic expectations openly during your consultation.
