Vision changes after a filler injection: call 112 immediately
Blurred or lost vision, pain in the eye, or symptoms such as facial drooping, weakness or difficulty speaking after a filler injection can mean that filler has blocked a blood vessel to the eye or brain. Call 112 straight away – do not wait for the clinic to call back.

Contact your injector immediately
If the skin turns pale, white or purple and mottled, or if you have severe pain that is getting worse. If you cannot reach the clinic, call 1177 or go to an emergency department.
Contact your injector or a health centre the same day
If you get pus-filled spots, open sores or dark, breaking-down skin near the injection area.
1. The Non-Negotiable Injector Checklist
The safety of any aesthetic procedure depends overwhelmingly on the medical judgment and anatomical knowledge of the practitioner. Before booking, ensure your provider satisfies these four criteria:
Medical License
Practitioners must hold an active registration with their national medical/nursing council (e.g., GMC, NMC, Socialstyrelsen).
Emergency Dissolving Protocol
Ask whether the clinic has hyaluronidase available and an emergency plan for complications.
Aseptic Clinical Environment
Treatments must occur in a medical-grade clinical setting, never in hair salons, private homes, or non-sterile rooms.
Complication Management Training
Your injector must be certified in recognizing early ischemia and treating delayed-onset nodular biofilms.
2. Anatomical Danger Zones
Certain facial regions harbor complex vascular networks where the risks of vascular compromise are heightened:
| Facial Region | Key Vascular Risk | Recommended Technique |
|---|---|---|
| Nasal Dorsum / Tip (Non-surgical Rhinoplasty) | Dorsal nasal & lateral nasal arteries (Direct connection to ophthalmic artery) | Micro-aliquots on bone, blunt microcannula, high-experience providers only |
| Glabella (Frown Lines) | Supratrochlear & supraorbital vessels (Highest blindness risk) | Botulinum toxin (neurotoxin) preferred; fillers generally contraindicated |
| Nasolabial Folds | Facial artery (Courses closely alongside the fold) | Cannula or deep periosteal bolus with careful aspiration |
| Lips & Vermilion Border | Superior & inferior labial arteries | Superficial submucosal placement, slow retrograde injection |
3. The Golden Rules of Recovery & Aftercare
- No strenuous exercise or heat (48 hours): Avoid saunas, hot tubs, and heavy weightlifting to reduce inflammatory edema.
- Sleep elevated: Use an extra pillow on your back for the first 2–3 nights to minimize unilateral swelling.
- No makeup for 24 hours: Keep needle puncture sites clean to prevent bacterial colonization and biofilm formation.
