Regenerative medicine brings together biologics, cell science, manufacturing and regulation. It is the focus of our next generation of company, Moleculeon Science and their sub-brand, Halyra.


The body already knows how to repair itself.
Cells repair tissue by sending signals. Some signals travel inside tiny vesicles. Others are growth factors. We learned how to make these signals pure, stable and consistent, so they can work in real products.

Extracellular Vesicles
Our vesicles come from plants, such as Centella asiatica, and from probiotic bacteria. Every batch is characterized before it leaves our hands. They are already used in skin, scalp and hair care.

Long-Acting Growth Factors
AvaFactor™ growth factors carry a stabilizing fusion domain. This keeps them active far longer than standard growth factors. They are made on our own biologics platform.

From ingredient to finished product
Our actives are already inside serums, masks and scalp care products in Asia. The science behind them is published in peer-reviewed journals.
The companies taking this science forward.

Moleculeon Science (正陀生技) studies regenerative longevity: growth factors and exosomes, applied to the biology of aging. Its lead program is in development in Taiwan.
