You describe a common consequence of filler injection in the temple area in someone with prominent veins. I observe this the most when I inject Sculptra into the temporal areas (due to the way Sculptra is reconstituted, higher amounts of fluid are injected into this compartment then with Juvederm). This is a result of some venous compression and is somewhat expected and something I warn patients about. On the other hand, care must be taken not to overly compress the veins in order not to cause any vascular compromise in this area. Therefore, I tend to inject this area slowly, with gentle massage, and I typically see the bulging resolve within 24 to 48 hours.
