High MW HA forms a dense occlusive film on the skin surface — proven to reduce transepidermal water loss by up to 40% in clinical studies.
Closely mimics native synovial fluid MW (1–10 MDa), making it the preferred grade for intra-articular injection raw materials.
Ultra-high purity, endotoxin-controlled batches available for eye-drop and ocular surgery formulations.
Maximum surface plumping and wrinkle-filling effect without injection — the most visible cosmetic result of any HA grade.
Widely used as positive control in HA research for viscosity, water retention, and film-formation studies.
Raw material for intra-articular injection products targeting osteoarthritis, knee pain, and joint lubrication.
Artificial tears, dry eye products, and surgical viscoelastics — where high viscosity and biocompatibility are essential.
Rich, occlusive face and body creams for severely dry, sensitive, and dehydrated skin conditions.
Medical wound care where HA forms a moist, protective environment to promote granulation and reduce scarring.
High MW HA is used as a biomaterial scaffold in tissue engineering and regenerative medicine research.
High-viscosity gels for facial treatment masks, pore-minimizing products, and bio-cellulose sheet masks.
