Most commercial hyaluronic acid products use only large-molecule HA — because it’s cheap to make.
(Think about it: if a bottle only costs a few hundred NT dollars, how much real HA can it contain?)
Worse yet, some unethical products add just a tiny bit of HA and bulk it up with thickening agents or polymers to mimic a "rich, concentrated" texture. That’s why some serums feel sticky or tight after use — it’s not hydration, it’s a fake film.
We use high-quality fermented hyaluronic acid derived from safe, biotechnology-based microbial sources — not just filler.
JOS combines three molecular weights in one smart formula, because each size serves a unique purpose:
High-Molecular HA: Attracts and retains moisture on the skin’s surface, forming a breathable hydration film to reduce water loss.
Mid-Molecular HA: Softens the outer layer of skin and supports the barrier function to maintain healthy texture.
Low-Molecular HA: Small enough to penetrate deeper into the skin, replenishing moisture from within and boosting inner hydration.
This layered hydration strategy gives you both instant smoothness and long-term moisture balance — without the sticky afterfeel.
