Mode of Administration:

Hylexxa® is a filling gel injected into the subcutaneous or deep dermis layer by authorized physicians Who have appropriate training and experience in injection techniques for volume restoration.

• Disinfect the area before injection.
• Remove the air by gently pushing down on the plunger to make a small amount of the product appear at the tip of the needle.
• Inject slowly and apply the least amount of pressure necessary.
• If the needle is blocked, do not increase the pressure on the plunger rod, instead, stop the injection and replace the needle.
• After needle insertion and before injection, it is recommended to withdraw the plunger slightly to aspirate and verify the needle is not intravascular.
• If immediate blanching occurs at any time during the injection, the injection should be stopped, and appropriate action such as massaging the area should be taken until it returns to normal color.
• The degree and duration of the correction depend on the character of the defect treated, tissue stress at the site, the depth of the implant, and the injection technique. The amount injected will depend on the areas which are to be corrected based on the experience of the medical practitioner.

Direction for assembly:

For optimal use of Hylexxa® products, it is essential that the needle is properly assembled to the syringe. See figure.

• STEP 1: Remove the tip cap: Hold the syringe, and pull the tip cap off, as shown in Figure A.
• STEP 2: Insert needle, hold the syringe body, and firmly insert the hub of the needle into the Luer-lock end of the syringe.
• STEP 3: Tighten the needle by turning it firmly in a clockwise direction (see Figure B) until it is seated in the proper position, as shown in Figure C.

NOTE: If the position of the needle cap is as shown in Figure D, it is not attached correctly. Continue to tighten until the needle is seated in the proper position.

STEP 4: Remove the needle cap, and hold the syringe body in one hand and the needle cap in the other. Pull in opposite directions to remove the needle cap without twisting, as shown in Figure E.
