Educational reading for licensed practitioners — not clinical or injection guidance.
The treatment ends when the needle is put down, but recovery is where the patient forms their opinion of the result. Good aftercare is not folklore — it is a short list of measures that genuinely reduce swelling and bruising, paired with clear guidance on the rare signs that need urgent attention. This is a general recovery framework, not personalised medical advice; a clinic's own instructions always take precedence.
The First 24 Hours
The initial day is about limiting swelling and protecting the treated area. Injection sites are tiny open channels, so the immediate priorities are cleanliness and calm. Cool compresses applied gently — never pressed hard onto fresh filler — help constrict vessels and settle early oedema. Most protocols advise avoiding strenuous exercise, alcohol and excessive heat for the first day, since all three increase blood flow and can worsen swelling or bruising; our piece on exercise after treatment covers the timing in more detail.
Makeup is usually best kept off fresh injection points for several hours to reduce infection risk. Sleeping slightly elevated on the first night can limit facial swelling. These are small measures, but they set the trajectory for the days that follow.
Days 2 to 4: Peak Swelling and Bruising
Swelling and bruising often look worse on day two or three than immediately after treatment — an entirely normal course that alarms patients who were not warned. This is the window where a topical bruise product such as creams for bruises can support the skin as discolouration surfaces and resolves. Barrier repair and soothing also matter: a gentle, fragrance-free balm like La Roche-Posay Cicaplast Baume B5+ keeps the skin calm without irritating fresh sites.
Continuing to avoid vigorous exercise, saunas and heavy alcohol through this window pays off. Gentle, cool skin, minimal manipulation and patience are the core of it. If lips or the under-eye were treated, expect these areas to swell disproportionately — they simply hold fluid more readily.
Days 5 to 14: Settling and Integration
By the end of the first week, most visible bruising has faded or become concealable and swelling has largely subsided. Filler continues to integrate with the tissue over roughly two weeks, which is why practitioners generally review results — and consider any tweaks — only after that point rather than judging the outcome on day one. This is also the phase where regenerative treatments show their supportive role: polynucleotides such as Plinest are used to promote skin repair and quality, and bio-remodelling with Profhilo supports the surrounding tissue, though these are planned as part of a course rather than as an emergency fix.
The Hyaluronidase Safety Net
Every clinic offering hyaluronic acid filler should have hyaluronidase — the enzyme that dissolves HA — on hand. It is not an aftercare routine; it is the safety net for two situations. The first is an unsatisfactory or lumpy result that the patient wants reversed. The second, far more urgent, is suspected vascular occlusion, where filler compromises blood supply — a genuine emergency signalled by disproportionate pain, blanching or dusky discolouration. Because hyaluronidase is central to safe practice, we cover stocking levels in how much hyaluronidase to stock.
Red Flags That Override Normal Recovery
Most recovery is uneventful, but patients must know the difference between expected healing and a warning sign. Escalating, severe or asymmetric pain, skin that turns white then mottled or dusky, vision changes, or signs of infection such as spreading redness, heat and fever are not part of normal aftercare — they warrant immediate contact with the clinic. Framing these clearly at discharge protects the patient and the practitioner alike. For the injector's side of that response, see the vascular occlusion protocol.
The Takeaway
Effective injectable aftercare is short and evidence-led: cool and protect the area for the first day, expect swelling and bruising to peak around days two to four, and allow up to two weeks for filler to settle before judging the result. Support the skin with bruise and barrier products, keep hyaluronidase available as the safety net for reversal and vascular emergencies, and make sure patients can recognise the red flags that override normal recovery.
