Most aesthetic treatments heal uneventfully, but complications can occur. Knowing which symptoms are normal, which warrant a call to your provider, and which require emergency attention can prevent serious outcomes.
Important Notice: This content provides general guidance about post-treatment symptoms. When in doubt, contact your provider or seek medical attention. Do not delay if you have concerning symptoms.
Normal vs Concerning Symptoms
Understanding the spectrum.
Expected symptoms: Most treatments cause predictable, temporary side effects that resolve on their own.
Concerning symptoms: Effects that fall outside normal range or progress unexpectedly.
Emergency symptoms: Signs requiring immediate attention to prevent serious harm.
The key difference: Normal symptoms improve over time. Concerning symptoms persist or worsen. Emergency symptoms are severe and escalating.
Emergency Symptoms After Injectables
Signs requiring immediate attention.
Vision changes (after filler): ANY visual changes after filler injection are emergencies.
- Blurred vision
- Vision loss in part or all of visual field
- Eye pain
- Changes in color perception
This could indicate: Vascular occlusion affecting retinal blood supply. Minutes matter for vision preservation.
Action: Go to emergency room immediately. Call your provider on the way.
Severe pain with color changes (filler): Intense, increasing pain along with skin blanching (turning white) then dusky/purple discoloration.
This could indicate: Vascular occlusion cutting blood supply to tissue.
Action: Contact provider immediately. If unavailable, go to emergency room.
Difficulty breathing or swallowing (neurotoxin): Progressive difficulty breathing, speaking, or swallowing after neurotoxin treatment.
This could indicate: Systemic spread of botulinum toxin (rare but serious).
Action: Go to emergency room immediately.
Severe allergic reaction: Difficulty breathing, swelling of throat or tongue, widespread hives, feeling of impending doom.
This could indicate: Anaphylaxis.
Action: Call 911 or go to emergency room immediately.
Emergency Symptoms After Laser/Energy Treatments
Signs requiring immediate attention.
Severe, worsening pain: Pain that increases significantly hours after treatment (not just immediate discomfort).
Signs of infection: Rapidly spreading redness, fever, increasing warmth, pus or unusual discharge.
This could indicate: Infection requiring immediate treatment.
Action: Contact provider immediately. If fever present, may need emergency room.
Extensive blistering: Unexpected, widespread blistering beyond what was discussed as possible.
Action: Contact provider immediately. Do not pop blisters.
Concerning But Not Emergency Symptoms
Signs warranting provider contact.
Persistent or increasing pain: Pain that doesn’t improve as expected over days.
Asymmetry: Noticeable asymmetry that doesn’t resolve with initial swelling.
Lumps or bumps: Nodules that persist beyond initial settling period.
Skin changes: Unexpected discoloration, texture changes, or slow healing.
Signs of mild infection: Increasing redness, warmth, or tenderness at treatment site.
Unexpected swelling: Swelling that seems excessive or doesn’t improve on expected timeline.
Action: Contact your provider during business hours. They’ll advise whether immediate evaluation is needed.
Normal Symptoms That Can Seem Alarming
Expected effects that concern patients.
Significant bruising: Bruising can be dramatic, especially around eyes or lips. Normal after injectable treatments.
Substantial swelling: Particularly with lip filler or certain facial treatments. Expected to peak at 48-72 hours.
Temporary numbness: Common after filler in certain areas. Usually resolves within weeks.
Skin shedding: Expected after peels and some laser treatments.
Darkening of spots: Pigmented lesions often darken before shedding after IPL/laser.
Redness lasting days: Normal after many treatments.
Mild tenderness: Expected at treatment sites.
These are normal if: They follow the timeline your provider discussed, they’re improving, and they’re not severe or escalating.
Timeline for Concern
When symptoms warrant attention.
First 24-48 hours: Emergency symptoms warrant immediate attention. Other symptoms are often too early to evaluate.
Days 2-7: Persistent or worsening symptoms warrant provider contact.
Weeks 1-2: Symptoms that haven’t begun improving warrant evaluation.
Beyond 2 weeks: Anything that hasn’t resolved or improved significantly should be discussed with provider.
What Information to Provide
When contacting provider or emergency services.
What treatment you had: Be specific about products, areas treated.
When treatment was: How many hours/days ago.
Symptoms: What you’re experiencing, when it started, how it’s progressed.
Severity: How severe on scale of 1-10, is it worsening?
Photos: If possible, take photos to share with provider.
Your location: In case emergency services needed.
Provider Accessibility
What to expect for after-hours concerns.
Provider availability: Good providers have systems for after-hours emergencies.
Ask in advance: How do I reach someone after hours if I have concerns?
Emergency contact: You should leave with contact information for emergencies.
Don’t wait: If you can’t reach provider and symptoms are concerning, seek emergency care.
Emergency Room Considerations
When and how to use emergency services.
When to go directly: Vision changes after filler, difficulty breathing, severe allergic reaction, symptoms suggesting vascular occlusion.
What to tell them: What procedure you had, when, what products were used (if known), and your symptoms.
Provider notification: If you go to ER, also notify your treating provider.
Follow-up: ER addresses immediate crisis; follow-up with your provider for ongoing care.
Prevention Through Preparation
Reducing emergency risk.
Choose qualified providers: Proper training reduces complication risk.
Discuss risks beforehand: Understanding possible complications helps you recognize them.
Get aftercare instructions: Written instructions for what’s normal and what’s not.
Save contact information: Have provider contact readily available.
Follow instructions: Aftercare instructions exist for good reasons.
Ask questions: Before treatment, ask what symptoms should prompt you to call.
Vascular Occlusion: The Critical Emergency
Special attention to this serious complication.
What it is: Blood vessel blocked by filler, cutting off blood supply to tissue.
High-risk areas: Nose, glabella (between eyebrows), nasolabial folds, forehead.
Symptoms: Severe pain (often out of proportion), blanching (whitening), then dusky/blue discoloration, cool skin.
Vision involvement: If vessel connects to eye circulation, vision changes occur.
Time sensitivity: Tissue damage begins within hours. Vision damage can be permanent within minutes to hours.
Treatment: Hyaluronidase dissolves HA filler. Must be administered quickly.
Why immediate action matters: Early treatment can restore blood flow before permanent damage. Delay can mean tissue death or permanent vision loss.
Creating Your Emergency Plan
Be prepared before treatment.
Before treatment:
- Save provider contact (including after-hours)
- Understand symptoms that warrant concern
- Know nearest emergency room location
- Have someone aware you’re having treatment
After treatment:
- Keep phone accessible
- Know timeline for normal symptoms
- Don’t hesitate to reach out if concerned
- Trust your instincts
Reminder: Most treatments proceed without complication. But knowing emergency signs allows rapid response if problems occur. Vision changes after filler, severe pain with skin color changes, and difficulty breathing are emergencies requiring immediate action. When in doubt, contact your provider or seek emergency care.
