The Science of Exosome Skincare

Exosome skincare is one of the most talked-about developments in professional beauty. This page explains what exosomes are, how stem cell and plant exosomes differ, how EboScience makes and tests its serums, and how to add exosome serum to your routine.

What Are Exosomes?

Exosomes are extremely small vesicles, measured in nanometres, that cells release naturally. You can think of them as tiny envelopes. Each one carries a mix of proteins, lipids and other molecules that cells use to send signals to one another.

In skincare, exosomes are valued for this role as messengers. Applied to the skin as part of a serum, they help skin look more hydrated, smoother and more even, and they make a natural partner for in-clinic facials.

Exosomes are also delicate. Heat and time can affect their quality, which is why exosome serums need careful handling, cold storage and short use-after-opening windows.

Stem Cell vs Plant Exosomes

Not all exosomes come from the same source. EboScience offers both stem cell and plant exosomes, because each suits different needs and preferences.

Stem Cell Exosomes

Our stem cell exosomes come from stem cells sourced from a cell bank. Using a cell bank means the starting material is consistent from batch to batch, which matters for a product used by professionals.

The stem cell exosome serum is our most concentrated formula. It comes in 1 ml syringes, five per box, so each dose is fresh and measured. Clinics use it as part of professional facials, and it can also be used at home as a targeted care step.

Plant Exosomes: Ginseng, Centella, Dandelion and Mugwort

Plants also release exosome-like vesicles. Our plant exosome serums use vesicles from four botanicals, each with a long history in skincare:

• Ginseng and Ginger (Revitalizing): for skin that looks tired and dull.
• Centella (Soothing): for skin that feels sensitive or stressed.
• Dandelion (Clarifying & Refreshing): for skin that needs a fresh, clear look.
• Mugwort (Defense & Balancing): for skin that needs balance and comfort.

Plant exosome serums come in 3 ml syringes, three per box. They can be used on their own or combined with the stem cell serum by your clinic professional.

How EboScience Serums Are Made and Tested

All EboScience serums are made in our own laboratory and production facility in Laval, Quebec.

• Strict standardized processes. Every batch is made in our Laval facility with clean facilities, controlled processes and documented batches.
• Rigorous quality control testing. Products are repeatedly tested and verified by our expert laboratory staff.
• Cold chain. Exosome serums are stored and shipped cold, with insulated packaging and ice packs, to protect their quality on the way to you.

Alongside our exosome serums, we make a line of LNP daily care serums. LNP stands for lipid nanoparticle: tiny lipid carriers that help deliver peptides in a lightweight, stable formula that does not need refrigeration.

How to Add Exosome Serum to Your Routine

Exosome serum works best as a focused step in a simple routine.

In-Clinic Use

Many of our partner clinics apply exosome serum during or after professional services such as hydrating facials. Your clinic professional will choose the serum and timing that suit your skin and your care plan.

At-Home Care

1. Cleanse your face and pat it dry.
2. Apply the exosome serum to your face and neck, pressing it in gently with your fingertips.
3. Wait a minimum of one hour before applying any other product.
4. For daily hydration between professional sessions, add an LNP daily care serum.

Storage and Shelf Life

Do not freeze exosome serums, and keep all products away from direct sunlight and heat.
