Hyaluronic Acid (HA)
Hyaluronic acid (HA) is a water-binding polysaccharide used across hydrating skin boosters and structural dermal fillers.
Hyaluronic acid (HA) is a water-binding polysaccharide used across two different kinds of product: freely dispersing hydrators in skin boosters, and cross-linked structural gels in dermal fillers. Cross-linking is what separates a structural HA filler from a freely dispersing hydrator. This page collects what HA is and everything KSTATION publishes about it.
What HA is
HA is a single class of molecule that behaves very differently depending on formulation. Uncross-linked, it binds water and disperses; cross-linked, it holds shape and provides structure. The same ingredient name therefore spans hydration boosters and volumizing fillers.
Forms it comes in
In the catalog, HA appears in monophasic and biphasic fillers across syringe formats, and in hydrating boosters. Filler products are intended for professional use.
How KSTATION verifies HA products
Manufacturer and licensing details are checked against Korean Ministry of Food and Drug Safety (MFDS) records before a product is listed, and we stock officially sourced products only. Read the full method in our Editorial & Sourcing Policy.
