How long after lip injections is it ok to take ibuprofen without causing more bruising?

I had my lips injected yesterday afternoon with Stylage (in Stockholm). I woke up with a headache this morning that will not subside, and I wanted to know if there was an amount of time I should wait before I take ibuprofen (24h? 48h? 1 week?). I bruise easily and already appear to have some bruising appearing, but I do not want to make it worse. Thanks!!
