Aethera Mésolab · fourth-generation exosomes
The era of signaling
Others deliver the active. We deliver the instruction.
Exosomes with EXOSIGNAL™ technology: the active reaches the skin together with the message that tells the cell what to do with it. Three professional protocols: repair, build and revitalize.
The principle
Why do two patients using the same product get different results?
Because the product delivers the material, but the instruction on what to do with it comes from each patient's body, and not every body gives it the same way.
Without signaling
- The active is deposited in the tissue
- The cell processes it according to its current state
- The response depends on each body
- Uneven results between patients
With EXOSIGNAL™
- The cell recognizes the exosome
- The exosome releases its load of mediators
- The specific biological pathway is activated
- A more orderly, predictable response
The active arrives together with the instruction.
Context
Three eras of aesthetic medicine
Each era did not replace the previous one; it built on it. This one does too.
The filler era
Volume was added from the outside. The result was visible, but it was not the patient's own skin.
The stimulation era
The fibroblast was provoked. The tissue was the patient's own, but the response had no direction.
The signaling era
The cell is instructed. Directed stimulation instead of a random reaction.
The line
Three protocols, one science
Each one combines exosomes with actives that carry out the signal, in freeze-dried vials reconstituted at the time of use.

Advanced repair and brightening system
Exosome + GHK-Cu
Repairs what others only hydrate. Skin barrier, reactive skin, tone and post-procedure recovery.

Fourth-generation regenerative biostimulation
Exosome + PLLA
The first biostimulator that does more than stimulate: it instructs. Firmness, dermal density and the patient's own collagen on face and body.

Advanced skin repair system
Ginseng + Centella
More than exosomes: multi-level regeneration. Botanical exosomes, PDRN, atelocollagen and peptides to revitalize the skin and support its recovery.

Which one for each patient?
| Exosome + PLLA | Exosome + GHK-Cu | |
|---|---|---|
| Main goal | Build structure | Repair and calm |
| Typical patient | Laxity, loss of density | Reactive skin, dark spots, post-procedure |
| Executing active | Poly-L-lactic acid | Copper tripeptide |
| Result | Progressive, matures over time | Visible from the first sessions |
| Areas | Face and body: 8 areas | Face, neck, décolleté and hands |
Quick rule: if the skin is losing firmness → PLLA. If the skin is damaged or irritated → GHK-Cu.
Where to buy
For twenty years we put things into the skin. Now we tell it what to do.
The Aethera Mésolab line is sold exclusively through authorized distributors.
