Swelling after collagen injections

Collagen injections are rare today. Was it bovine (from cow hide) or was it human collagen? Bovine collagen can cause allergic reactions in 1 - 3 % of the population. It is very rare with the use of human collagen. Swelling can occur for a number of reasons. You should see your injector to be evaluated and reassured.
