Restylane Kysse Imported

The manufacturer gives a single indication: to augment or add volume to the lips.

Technique and injection sites are the injecting doctor's decision for each person.

It should not be used in people with a history of streptococcal protein allergy, a history of severe allergy such as anaphylaxis, or allergy to lidocaine or amide-type local anaesthetics. Use should be postponed if the area or tissue nearby is inflamed, infected or has a tumour, and the manufacturer says safety in pregnancy, breastfeeding and under age 18 has not been established.

The key warning is that it must not be injected into a blood vessel, which can cause a blockage, ischaemia or tissue death. Rare serious events such as blindness, stroke and skin necrosis have been reported. A change in vision, whitening of the skin or unusual pain during or soon after injection means the injection must stop at once and a doctor must be seen.

People who bleed easily, or take medicines affecting platelets or blood clotting, may bruise more. Bruising, redness, itching, swelling and soreness at the site can follow, and the manufacturer says they usually clear within a few days to a week. Avoid strong sun, UV and extreme temperatures until swelling and redness settle.

Store at no more than 25 °C, do not freeze, and keep out of sunlight, as the manufacturer states.

Single-use only and not to be re-sterilised; the syringe, needles and any remainder are discarded after treatment.
