ExoHealer™ is the exosome contained in P198's ExoOrigin-CM™, derived from umbilical cord blood stem cell conditioned media. Exosomes are tiny particles naturally released by cells that carry growth factors and other signaling molecules; ExoHealer™ delivers these to the skin (or scalp) to support the skin's own regeneration and repair processes.

Among adult-derived stem cell sources, umbilical cord blood stem cells are the youngest and healthiest, with stronger immune-modulating ability, cell proliferation, and differentiation potential than bone marrow– or adipose-derived stem cells, and they're less affected by donor-to-donor variability. They're also sourced without the ethical concerns associated with embryonic stem cells.

Lab studies on the conditioned media cited by the manufacturer show several effects: increased collagen I and III synthesis, reduced pro-inflammatory cytokines (TNF-α, IL-6), free-radical scavenging (antioxidant activity), and faster fibroblast migration to support wound/tissue repair. In practice, clients are often treated for concerns like fine lines, loss of elasticity, dull tone, enlarged pores, dryness, and inflammation/acne-prone skin.

No. No stem cells themselves are injected or applied — the product contains the conditioned media/exosomes that stem cells produce, not live cells. It's formulated and manufactured as a cosmetic ingredient for clinic and hospital use, not a pharmaceutical or a stem cell therapy.

The lyophilized (freeze-dried) powder is reconstituted with P198's Activating Solution, Boosting Solution, or saline, then applied to the skin and absorbed — typically as part of an MTS (microneedling/needle-free delivery) procedure. It's recommended to shake the solution thoroughly and use it immediately after mixing.

This varies by individual skin condition, but effects are typically noticeable 3–7 days after the procedure and may last approximately 3–6 months.

A single session can be effective, but on average 3–5 sessions are recommended for optimal, longer-lasting results.

ExoHealer™ itself is a topical skin booster that doesn't involve heat or create wounds, so it's considered a low-risk addition to a procedure. That said, pain, redness, or swelling depend on what it's combined with (e.g., microneedling, RF, laser) and can vary by individual — clients should ask their provider what to expect for their specific treatment plan.

The formulations are dermatologically tested and preservative-free (no artificial fragrance or color). As with any skin treatment, clients with known allergies, active skin infections, or specific medical conditions should discuss their history with the provider beforehand, and any product-specific precautions should be reviewed with the treating clinic.

Case examples in the clinical guidebook include clients with sensitive, reactive, or acne-prone skin who saw improvement in redness, breakouts, and barrier strength after a course of treatments — always assessed and tailored by the treating provider.
