Due to topical anaesthesia being applied to the skin and also being present in the filler itself,  numbness will be felt in that area for a couple of hours after the treatment. Following treatment, some redness, swelling and\or bruising may be noticeable. Whilst everything possible is done to avoid this, I always recommend that dermal filler treatment be planned with respect to any upcoming engagements – you should expect to look your best approximately 2 weeks after application.
