Dermal filler risks, explained honestly.
Filler is a medical procedure, and you deserve the conversation a medical procedure gets. This is the one we have at consultation, written down.
The short answer: common effects are short-lived and cosmetic: bruising, swelling, tenderness for a few days. Uncommon problems, lumps, asymmetry, migration, are usually correctable, often by dissolving. Rare complications are serious, above all filler entering a blood vessel, and they are exactly why who treats you matters more than any other choice you make.
Common, and short-lived
Expect some of: bruising, swelling, tenderness, and occasionally a small firmness you can feel (not see) while the product settles over the first days and weeks. These are the ordinary costs of putting a needle in a face, they resolve on their own, and aftercare instructions cover them. Plan social downtime around the under-eyes especially, where bruising shows most.
Uncommon, and usually correctable
- Asymmetry that persists after settling, adjusted at review.
- Lumps or nodules that don't soften, usually managed by massage, time, or dissolving.
- Migration, product sitting outside where it was placed, associated with overfilling and poor technique, corrected by dissolving.
- Late swelling episodes, an uncommon immune response that can appear months later, managed medically.
The common thread: hyaluronic-acid filler is dissolvable, so most cosmetic problems have an exit. The honest limit, and this clinic's standing line, is that the filler dissolves, not every complication does.
Rare, and serious
The complication that matters most is vascular occlusion: filler entering or compressing a blood vessel, starving tissue of blood. Untreated, it can cause tissue damage, and in the worst documented cases, where vessels connected to the eye are involved, sight loss. It is rare, and it is the entire argument for doctor-led treatment: prevention through anatomical technique, recognition within minutes, and immediate treatment, with dissolving agent kept in the room, never ordered in. Ask any clinic, anywhere, what their vascular occlusion protocol is. A good one answers instantly; a dangerous one asks what you mean.
Who shouldn't be treated, or not yet
- Anyone with an active skin infection near the treatment area, treated after it clears.
- Anyone acutely unwell, or with certain conditions and medications that need weighing first, which is what the medical history at consultation is for.
- Pregnancy and breastfeeding, deferred as standard practice.
- Anyone whose expectations filler cannot meet. Being told "no, and here's why" is a safety feature, and it happens here regularly.
What a safe clinic looks like
A doctor doing both the assessing and the injecting, not "oversight" from another room. Premium, UKCA/CE-marked product with a name they'll tell you. Volumes and prices agreed with you before anything is opened. Dissolving agent on-site and an emergency protocol they can recite. Aftercare with a direct contact, and reviews as standard, all of which is simply how this clinic is built. Individual results, and side effects, vary; the consultation is where your personal risk picture gets assessed properly.
Related questions
Asked alongside this one.
Is dermal filler safe?
In trained medical hands, with good product and honest planning, it is a low-risk procedure whose common effects are minor and temporary. The serious risks are rare and are overwhelmingly a function of who is injecting and how they respond when something goes wrong, which is why "who" is the real safety decision.
What should I ask any clinic before booking?
Four questions: Who exactly will inject me, and are they a doctor? What product will you use? What is your vascular occlusion protocol, and is dissolving agent on-site? What aftercare and review do I get? Any clinic bothered by those questions has answered them.
Can I drink or train after treatment?
You'll leave with specific aftercare, and the general shape is: take it easy on alcohol and hard training for the first day or two, both increase bruising and swelling, avoid pressure on the area, and let the product settle. Most men are back at work the same day.
