Dermal Fillers


Small risk of delayed hypersensitivity reaction to fillers during the COVID-19 pandemic


There is some evidence that viral infections may trigger a delayed immunological reaction against dermal fillers.

These reactions are characterised by redness and swelling. Reactions usually occur 48-72 hours after the injection but can be delayed (occurring a few weeks to months after).

On a positive note:

Delayed reactions after dermal fillers remain rare complications. Their cause is still uncertain and may not be linked to a viral infection. This may be purely coincidental.


Also, although the symptoms may be inconvenient, they will not be life-threatening and may settle spontaneously.



These reactions are usually treated with oral steroids, which are not recommended to be used currently. Please be aware that this option may not be available to you should you be unfortunate enough to get this delayed reaction.
