Short answer: Exosome serums signal skin to look fresher, smoother and firmer over time. Use one morning and night, under a balm or oil, and give it time. Here are the seven questions we hear most.
1. Do exosome serums actually work?
The science of exosomes in skincare is young and growing. What we see with steady use: fine lines look softer, tone looks more even, skin looks more luminous.
We pair exosomes with copper peptide (GHK-Cu), one of the most studied peptides in skincare. Signal, then rebuild.
The longer answer: Are Exosome Serums Worth It?
2. What is an exosome, anyway?
A tiny messenger cells send to each other. Not a stem cell. Not alive. Full explainer: What Is an Exosome?
3. How long does an exosome serum take to work?
Hydration and glow tend to show first. Fine lines and firmness take longer.
Consistency beats speed. Morning and night, every day.
4. Is an exosome serum safe for sensitive skin?
Ours is built to be gentle. Centella, panthenol and sodium hyaluronate keep skin calm and hydrated. It is a gentle choice even after a facial or peel.
New to it? Patch test first.
5. Where does an exosome serum go in my routine?
- Cleanse.
- Mist.
- Exosome serum. Wait a few minutes.
- Seal with Field Glow Facial Oil or Blue Hour Tallow Balm.
Signal first, seal last. Read Exosomes and Tallow.
6. Can I use it with a copper peptide serum?
Yes. Pair it with Emberline Copper Peptide Serum to keep copper peptide working through every layer.
7. Is the Exosome + GHK-Cu Serum vegan?
No. It contains royal jelly. It is cruelty-free.
Why is it so limited?
It is made in small batches. When a batch is gone, it is gone until the next one.
