How to Alleviate Swelling on Lips After Restylane?

Restylane injected into the lips can cause swelling for 3 to 5 days, longer if bruising is present.  Intermittent cold packs will help.  You could also try taking an antihistamine if you do not have any contraindications, although it works best if taken a few hours before the injections.  Try it next time.

The best way to alleviate is it is to avoid it. I do not make light of your issue but in in the interest of education, a full response is in order.
Swelling may be due to a reaction to the filler, to the injector hitting a blood vessel or a combination of both.
To blunt the inflammatory response, we try and use 3 doses of Celebrex (just after the procedure and daily for 2 days after wards). The problem is that the drug cannot be given to people with Sulfa allergies. Swelling can be somewhat alleviated with ice for 24 hours, if needed.
All this swelling WILL come down. You may not be convinced but ask anyone who was ever hit in the lip and they will confirm this.
When you are happy with your results, the anxiety associated with the swelling will be a memory. But - don't forget next time to see if you can get your Celebrex (I am not sure what the Aussie equivalent of this Cox2 inhibitor is) and to ice after wards.
Cheer up. You are going to be OK.
