Q3｜How Are Exosomes Different from “Stem Cells”?

In 2013, the Nobel Prize in Physiology or Medicine established the cellular “vesicle trafficking” mechanism—essentially the instruction manual for how cells package and deliver signals. That insight helps us understand and modulate exosome formation and release, opening possibilities in skin and aesthetic care. Exosomes have since been widely explored as one of the most promising ways to break long-standing bottlenecks in regeneration and repair.

TL;DR

They’re fundamentally different. Cosmetics do not contain live cells. We use exosome-rich actives purified from cell secretions, delivered in a freeze-dried powder + dedicated diluent format. Everything is produced and listed under cosmetic regulations, with batch-by-batch QC and per-vial traceability.

01｜Let’s define the three things first

• Stem cells: live cells capable of self-renewal and multi-lineage differentiation. Clinical use belongs to medical contexts—not cosmetics.
  
  

• Exosomes: nano vesicles (≈30–150 nm) secreted by cells, wrapped in a lipid bilayer and carrying proteins/peptides/lipids/nucleic-acid fragments—the messengers of cell-to-cell communication. They are not live cells.
  
  

• “Stem-cell skincare” (marketing term): most products use plant cell culture extracts or conditioned media/derived signal mixes; you’re not rubbing live cells on skin.

02｜What’s allowed (and not) in cosmetics?

✅ Allowed in cosmetics

• No live cells; permitted to use cell-derived, acellular secretions (e.g., exosome-based actives) that meet microbial/endotoxin and other quality limits.
  
  

❌ Not allowed in cosmetics

• No medical claims (diagnose/treat/cure/prevent disease); no live cells.
  
  

What we actually do

• Use exosome-rich actives (secretion → purification → quality release), then freeze-dry to lock freshness and reconstitute with a dedicated diluent right before use.
  
  

• Produce and list per cosmetic regulations with INCI disclosure; keep source/quality files on record (e.g., DMF on file/technical documentation for traceability, where applicable).
  
  

• Operate Fresh-Batch 48h: within 48 hours of order, allocate latest released batch, print per-vial labels, and ship with temperature awareness.

03｜One look: Stem Cells vs. Exosomes

Bottom line: We sell exosomes, not stem cells. Think “cell language,” not “cells themselves.”

04｜Why exosomes are our go-to partner after microneedling

• Perfect timing: microneedling opens microchannels; the 0–60 min window is prime for delivery. Freshly reconstituted exosomes hit that window.
  
  

• Signal-level care: more like giving skin clear instructions; pair with a calming mask for a fast drop in tight/dry/red sensations.
  
  

• Simpler, gentler formulas: freeze-dried + fresh use reduces dependence on heavy preservative systems—friendlier for reactive skin.

05｜Source & quality: the three panels people really care about

Per eligible batch (examples; panels vary by batch), we implement release testing such as:

• Identity/characterization: size & distribution (e.g., NTA), typical markers (e.g., CD9/CD63/CD81).
  
  

• Safety panel: bioburden/endotoxin, yeast/mold, mycoplasma, heavy metals and residual solvent limits.
  
  

• Physico-chemical & stability: pH, osmolality, appearance, accelerated/long-term stability observations.
  
  

Every vial carries LOT + Vial-ID. Scan the QR to reach the Trace Page for COA summary and temperature-control notes.

06｜What exactly do we sell?

• Format: Freeze-dried powder + dedicated diluent (dual-chamber freshness). One vial = one standard session.
  
  

• Workflow: D0 (procedure day) microneedling → reconstitute in ~10 s → apply full vial → 10–15 min calming mask.
  
  

• Cadence: every 7–10 days; 3 sessions ≈ one condensed cycle.
  
  

• Sets: Pro (1+1) / Max (2+2) / Ultra (3+3) for single, two-week, and 3–4 week rhythms.

07｜Quick Q&A

Q: Is this a “stem-cell cream” or “stem-cell therapy”?

A: No. We don’t use live cells. We provide exosome-based, acellular signal carriers for cosmetic care.

Q: Will exosomes change my DNA?

A: No. This is topical, surface-level care focused on comfort and barrier support. Quality panels control nucleic-acid residues and safety limits.

Q: How is “plant stem-cell skincare” related to this?

A: Different concept. Plant “stem-cell” products are plant culture extracts; our actives are cell secretions (exosomes)—different processes and mechanisms.

Q: Why must I use the dedicated diluent? Can I use purified water?

A: Our diluent provides isotonicity + skin-friendly pH + gentle buffering, helping stability and comfort for up to 48 h after reconstitution. Do not replace with water/saline.

Q: Why not ship it pre-mixed?

A: Once reconstituted, sensitivity to temperature/agitation spikes and hygiene control gets harder. We insist on fresh mix-at-use and Fresh-Batch 48h so you receive the latest released batch.

One-line wrap

Exosomes ≠ stem cells. We deliver the language between cells, not the cells: freeze-dry to preserve, reconstitute to hit the window, and use per-vial traceability so every detail is verifiable in your hands.
