Product Description

Description
Hyaluronan   is a colorless, transparent, viscoelastic, biodegradable, non-pyrogenic and sterile gel, supplied in a prefilled glass syringe. Hyaluronan consists of cross-linked sodium hyaluronate from biofermentation and formulated to a concentration of 20 mg/ml, suspended in a physiological buffer pH 7. Sodium hyaluronate is a natural polymer of repeating disaccharide units of N-acetyl-D-glucosamine and sodium glucuronate linked by glycosidic bonds, which is widely distributed in the extracellular matrix in both animals and human. After slightly cross-linking, it also has good biocompatibility. Hyaluronan   is supplied in a disposable glass syringe with a luer-lock fitting. The syringe is equipped with a plunger stopper, finger grip and plunger rod and packed in a blister together with two sterile needles.

Dosage
Defects should be fully corrected but not overcorrected, a maximum dosage of 1.5ml per injection site is recommended.
Treatment procedure 
Hyaluronan should be used after indoor temperature balance.
LocaI anaIgesia(ice,topical analgesics or local infiltration, and/or nerve block with 1% lidocaine solution) is provided before treatmen at the discretion of the doctor.
Before injection,press the rod carefully until a small droplet is visible at the tipof the needle.
Inject Hyaluronan while pulling the needle slowly backwards and stop injecting just before the needle pulled out from the skin to prevent material from leaking out from the injection site.
Once the injetion is completed, the injection site is manually massaged to allow Hyaluronan   to conform to the contours of the adjacent tissues.
After injection, if the treated area is swollen,melting ice can be applied on the site for a short period.
