The side effects – if properly administered – are extremely rare at Cosmedics Skin Clinics.
Some patients experience a small bruise at the injection site. This normally fades after a few days
5-10% of patients have headaches for the first 24 hours. These are quite easily managed with paracetamol.
The more severe side effects are commonly due to poor practice – most likely in cheap or non-medical establishments or overdosing. These can include a droopy eyebrow or eyelid and this can last a few months.
