A contraindication is when you should not consider dermal fillers:
Skin infection near the site of injection
Allergy to hyaluronic acid
Suppose you were taking clopidogrel, aspirin, high dose vitamin C or omega-three oils. In that case, you may need to stop those one week before your appointment, as long as it is not a medical contraindication.
Avoid wearing make-up until the next day to keep the area clean.
Do not use sunbeds, sauna, or steam room until any swelling has resolved after Dermal Fillers.
