After procedures such as botox, fillers, mesotherapy and laser, mild swelling, redness and bruising are expected and temporary. However, some signs — disproportionate pain, skin blanching, vision change, spreading redness with fever, or shortness of breath — require urgent assessment. This is a triage guide to help you tell normal healing from warning signs.
Important
This is not medical advice. When in doubt, always contact the physician who performed the procedure; in emergencies go to the nearest medical facility.
The general rule
Expected side effects are mild, limited and steadily decreasing. Warning signs are severe, disproportionate, spreading or worsening. If in doubt, do not wait — you are one phone call away.
✅ Usually normal (expected) findings
- Mild redness and bump-like swelling at injection points (subsides within hours).
- Limited bruising (needle-related, fades within a few days).
- Mild tenderness/tightness.
- Mild swelling and a sense of asymmetry in the first days with fillers (the settling process).
- Transient redness and a warm sensation after laser.
- With botox, the effect sets in over a few days to two weeks; seeing no change in the first days is normal.
⚠️ Findings that warrant contacting the physician (semi-urgent)
- Swelling/pain that lasts longer or increases more than expected.
- Hardness, a lump (nodule) or late-onset swelling after fillers.
- Increasing redness, warmth and tenderness at the injection site (possible infection).
- Marked, non-resolving asymmetry.
- Eyelid/brow drop after botox (temporary but should be assessed).
🚨 Emergency — go to a medical facility immediately
- Disproportionate, severe pain + skin blanching + mottled discolouration → suspected vascular occlusion with fillers (a medical emergency).
- Sudden vision change / vision loss, severe eye pain → seek emergency/ophthalmology care immediately.
- Spreading redness + fever, malaise → may indicate serious infection.
- Sudden swelling of the face/tongue, shortness of breath, itchy rash → suspected allergic/anaphylactic reaction; call emergency services.
- After botox, difficulty swallowing, double vision, generalised muscle weakness, difficulty breathing → rare but serious; seek care immediately.
Quick view by procedure
| Procedure | Expected | Contact physician | Emergency |
|---|---|---|---|
| Botox | mild redness, headache | eyelid/brow drop, asymmetry | swallowing/breathing difficulty, widespread weakness |
| Filler | swelling, bruising, settling | nodule, late swelling, infection | blanching+pain (occlusion), vision loss |
| Mesotherapy | spot redness | prolonged swelling, infection | allergic reaction |
| Laser | redness, warmth | blistering/burn, prolonged redness | widespread infection |
To reduce risk
- Have the procedure done by an experienced, physician-led team in appropriate clinical conditions.
- Follow after-care instructions (no rubbing, avoiding sun/heat, etc.).
- Make early contact when in doubt — waiting usually makes things harder.
