Nanomère: We make probiotic yeast exosomes for anti-aging skincare.
We grow them in bioreactors, load them with skincare actives, and test their effects on the visible signs of skin aging.
Our yeast exosomes are active on their own and carry added skincare actives.
Active on their own
Loaded with skincare actives

Saccharomyces boulardii ferments in standard bioreactors. Production scales by running a bigger vessel.
It is a probiotic yeast already used in consumer products, on a regulatory path that is well travelled.
Grow and isolate
We grow S. boulardii in bioreactors, then separate the exosomes it releases from everything else in the broth — first by size, then by filtration, until what is left is the vesicles on their own.
We focus on ingredients designed to improve the appearance of aging skin.
We target skin firmness, elasticity, oxidative stress and barrier function.


Our exosomes are designed for formulations such as:
- Anti-aging serums
- Night treatments
- Concentrates
- Creams and emulsions
- Eye treatments
- Professional ampoules
Bring us an active and a format.
We will come back with what the platform can do for it.
