1. Dextran
- Major ingredient of 5%D/W infusion solution is d-glucose, and Dextran polymer of d-glucose is also certified as safe as it has long been used as plasma infusion solution.
- Like HA, it is Polysaccharide and less allergic reaction doesn't require allergic reaction test.
- Endotoxin level is too low even to measure so it is certified as safe from toxicity.
- Raw material biodegrades in a body within 1-2 years.
2. PMMA(Polymethyl methacrylate)
- PMMA is a permanent filler certified as safe because PMMA is an important material of Artefill certified by US FDA.
- PMMA is widely used for dental treatment such as dental prosthetics and is safe even if inserted in a body.
- Due to less allergic reaction, allergic reaction test is rarely required before use and is safe from toxicity due to the immeasurably tiny amount of Endotoxin.
- PMMA doesn't decompose after injected in a body so the volume effect remains for a long time. The volume PMMA accounts for is merely about 10%, but as it creates surrounding collagen tissues, the injected material is so grafted rapidly that it doesn't move, thereby bring about volume effect.
3. Lidocaine
- Lidocaine is added to relieve pain that may arise during treatment.
