What are exosomes and why are they used in aesthetics?+
Exosomes are nano-sized (30–150nm) extracellular vesicles produced by stem cells and other cell types. They serve as cell-to-cell communication vehicles, carrying growth factors, microRNAs, and proteins that instruct recipient cells to repair and regenerate. In aesthetics, exosomes derived from mesenchymal stem cells (MSCs) deliver a concentrated regenerative signal to skin cells — stimulating collagen production, reducing inflammation, and improving cellular function at a level beyond what PRP alone can achieve.
How is Cell Factor different from PRP or PDRN?+
PRP delivers your own platelet growth factors. PDRN delivers nucleotide building blocks for cellular repair. Cell Factor exosomes deliver hundreds of distinct signaling proteins and nucleic acids from MSCs that orchestrate a more complex regenerative response — essentially communicating with multiple cell types simultaneously to promote repair, anti-inflammation, and rejuvenation. The mechanisms are complementary, which is why BHRC Westlake Village often combines all three in advanced regenerative protocols.
Is exosome therapy FDA-approved?+
Exosomes for aesthetic use are offered under physician oversight as a biologic treatment. The FDA has not yet issued specific approval for cosmetic exosome injectables (as of 2026), but the products used at BHRC Westlake Village are produced in licensed facilities under stringent quality controls. Your BHRC provider will fully discuss the regulatory status and clinical evidence during your consultation.
What does Cell Factor exosome treatment at BHRC Westlake Village feel like?+
Cell Factor is typically applied topically after a skin-preparation procedure (microneedling or Morpheus8) that creates channels for penetration, or injected directly into the scalp for hair restoration. Topical application involves no additional discomfort. Scalp injections use topical numbing. There is minimal to no downtime from the exosome application itself.
How many Cell Factor sessions do I need?+
For skin rejuvenation, most BHRC Westlake Village patients see transformative results with a series of 3 sessions. When used as an accelerant post-procedure, a single application per Morpheus8 or CO2 session is typical. For hair restoration, 4–6 sessions are recommended for initial treatment, with maintenance sessions every 6–12 months.
Is Cell Factor safe?+
Cell Factor uses exosomes derived from vetted, tested mesenchymal stem cell sources. The purification process removes live cells, ensuring no risk of cell transplantation or immune reaction. BHRC Westlake Village works with Cell Factor's clinical-grade manufacturing partners and follows all safety protocols. Patients are screened before treatment.
What areas can Cell Factor treat at BHRC Westlake Village?+
Cell Factor exosome therapy at BHRC Westlake Village is used for full facial rejuvenation, under-eye area, neck and décolletage, post-procedure healing (after CO2 laser, Morpheus8, or aggressive microneedling), and scalp hair restoration. The treatment is applied where cells need the strongest regenerative signal.
How quickly does Cell Factor work?+
Cell Factor exosomes begin signaling immediately upon application. Post-Morpheus8 patients often notice dramatically reduced redness and faster healing within 24–48 hours. For standalone facial rejuvenation, visible improvement in skin quality typically appears over 4–8 weeks as collagen production responds to the exosome signals.
