Swelling after any filler may depend on:
1. Location of face, e.g. the tear trough of the upper cheek may swell more than the mid cheek
2. How many injections were needed
3. What size needle was used
4. How much product was used
5. How fast or slow the needle was inserted and the product injected
In general one to two days of swelling can be expected, but it could last even more than a week, and bruising can be minimal to moderate lasting a few days to two weeks. There has been at least one medical study discussing the merits of using Arnica montana, an herb,taken orally, to reduce swelling after facelifts, and this may help with swelling of fillers as well, and may reduce bruising too.
