High Concentration Of Stabilized Hyaluronic Acid
HYLO refers to High Molecular Weight Hyaluronic Acid (H-HA) and Low Molecular Weight Hyaluronic Acid (L-HA). It is a proprietary technology developed by FHL for the production of Fulloria, utilizing a specialized method that involves precise temperatures and stirring/mixing speeds. The HYLO technology aims to enhance the covalent bonds of the existing hyaluronic acid while also promoting ongoing skin regeneration through the strategic arrangement of the hyaluronic acid molecules.


Structural stability is enhanced without the need of a crosslinking agent through FHL’s proprietary formulation and manufacturing process.
Once administered, FULLORIA permeates the tissue and interacts uniquely with each layer of the skin.
High and Low HA FULLORIA creates the ideal physiological conditions for the proliferation, migration and organization of keratinocytes, fibroblasts and adipocytes.
