Which Layer Does Stem Cell Conditioned Media Work On?2026.03.23
Understanding the Difference Between Epidermis, Dermis, and Subcutaneous Layer
A common misconception in regenerative medicine is:
“If you apply or inject it, it will work.”
However, in reality:
The outcome depends heavily on where the active components are delivered.
Even with the same substance,
if it reaches a different layer, it becomes an entirely different treatment.
The Skin Has Three Main Layers
The skin is composed of:
- Epidermis
- Dermis
- Subcutaneous layer
And:
Hair growth and skin improvement depend on which layer is targeted.
When It Reaches the Epidermis
Effects
- Improved barrier function
- Hydration
- Mild anti-inflammatory effect
Limitations
The epidermis:
Does not produce hair.
Therefore:
- Hair growth effect is minimal
- Effects are limited to surface-level skin improvement
When It Reaches the Dermis
This is a key layer.
The dermis contains:
- Hair follicles
- Dermal papilla
- Fibroblasts
Effects
- Collagen regeneration
- Improved follicular environment
- Improved blood circulation
In other words:
This layer directly influences the environment where hair grows.
When It Reaches the Subcutaneous Layer
In deeper layers:
The hair follicle stem cell niche exists
Effects
- Activation of stem cells
- Restarting the hair cycle
- Improvement of long-term hair growth potential
Reaching this layer means:
Potentially activating the core mechanism of hair growth
Why Topical Application Alone Is Not Enough
The skin has a strong barrier function.
Therefore:
- Topical application
- Superficial delivery
often result in:
Most active substances remaining in the epidermis
The Role of Morpheus8
Morpheus8:
- Creates microchannels into deeper layers
- Activates tissue with RF energy
This allows:
Direct delivery into the dermis and subcutaneous layer
In other words:
It enables delivery to the “effective layer.”
The AVAN TOKYO Treatment Design
At AVAN TOKYO, we focus on:
Designing the target layer
We determine:
- Whether to target the epidermis
- The dermis
- Or deeper layers
By adjusting:
- Depth (in millimeters)
- Energy
- Delivery method
Why Results Differ with the Same Substance
A common clinical reality:
- Simply applying → limited effect
- Shallow delivery → skin improvement only
- Precise deep delivery → structural and hair growth improvement
Therefore:
The difference lies not in the substance, but in the treatment design.
Final Thoughts
Stem cell conditioned media is not a “magic solution.”
What truly matters is:
Which layer it reaches and how it is delivered
“Regenerative Medicine Is Determined by Depth”
Skin and scalp treatments are evolving from:
“the era of ingredients”
to “the era of treatment design”
At AVAN TOKYO, we integrate:
depth × layer × regeneration
to achieve optimal results.
