The protocol that adds the most value

And if they need both


They don't compete. They go in order.

Exosome + GHK-Cu and Exosome + PLLA share EXOSIGNAL™ technology and complement each other: first the tissue is repaired, then structure is built on it.

Phase 1

Exosome + GHK-Cu

Repairs the barrier and calms the tissue. Prepares the ground.

1 session every 14 days · 1 box = 3 sessions

Exosome + GHK-Cu
Phase 2

Exosome + PLLA

On healthy tissue, neocollagenesis performs better.

1 session every 4 weeks · 1 box = 3 sessions

Exosome + PLLA

First repair, then build.

Frequently asked questions

Combined protocol

Why start with GHK-Cu rather than PLLA?

Because neocollagenesis performs better on healthy tissue. GHK-Cu repairs the barrier, calms inflammation and prepares the ground; PLLA then builds structure.

How many boxes does the combined protocol require?

One box of each product per patient: 3 sessions of Exosome + GHK-Cu and 3 sessions of Exosome + PLLA. The final frequency is decided by the treating professional.

The order, number of sessions and interval between phases must be individualized according to the treating professional's assessment.
