Which Growth Factors Matter Most?2026.03.27
— Breaking Down the Roles of EGF, FGF, and VEGF —
Many treatments claim:
“Stem cell conditioned media contains many growth factors.”
However, what truly matters is not just their presence.
It is understanding:
which growth factor works, where, and how.
At AVAN TOKYO, we do not simply “apply” growth factors.
We design treatments based on how each factor functions and interacts.
Growth Factors Work as a System
Regeneration is not driven by a single factor.
It requires coordination between multiple growth factors.
Among them, the most essential are:
EGF, FGF, and VEGF
1. EGF: The “Activation Switch”
EGF (Epidermal Growth Factor) stimulates:
- Cell proliferation
- Activation of hair follicle cells
- Wound healing and re-epithelialization
It acts as a trigger, telling cells to regenerate.
In hair treatment, EGF essentially signals:
“Restart growth.”

2. FGF: The “Architect” of Tissue
FGF (Fibroblast Growth Factor) is responsible for:
- Activating fibroblasts
- Producing collagen and elastin
- Supporting vascular formation
- Maintaining hair follicle stem cells
While EGF starts the process,
FGF determines how well the tissue is rebuilt.
It directly affects:
skin quality, elasticity, and hair thickness.

3. VEGF: The “Infrastructure” of Blood Flow
VEGF (Vascular Endothelial Growth Factor) promotes:
- Formation of new blood vessels
- Nutrient delivery
- Oxygen supply
Without blood flow,
no regeneration can be sustained.
VEGF creates the foundation that supports all healing.

The Key Is Not “Which Is Best”
It is not about choosing one.
✔ EGF activates
✔ FGF builds
✔ VEGF supports
Only when these work together
does true regeneration occur.
The AVAN TOKYO Approach
At AVAN TOKYO, we maximize these effects through:
- RF stimulation with Morpheus8
- Precise delivery to dermis and fat layers
- Stem cell conditioned media applied to the correct depth
This is not surface-level care.
It is controlled, targeted regeneration.
Conclusion
Growth factors alone are not enough.
But when delivered correctly,
to the right layer, at the right timing—
the tissue begins to transform.
Final Message
If you are noticing hair thinning or loss,
the issue may not be the treatment itself—
but the environment for regeneration.
At AVAN TOKYO, we rebuild that environment
from the cellular level.
