Aftercare Guide

Lip Fillers Aftercare

Lip filler aftercare is simpler than most patients expect, but the first 48 hours really matter. Here's exactly what to do — and what to avoid.

First 24 Hours

The most important window for optimal results

  • Apply cold compress (wrapped in gauze/cloth) for 10 minutes at a time to reduce swelling
  • Drink plenty of water, but avoid drinking with a straw for 48 hours
  • Avoid hot drinks and spicy foods for 24 hours (heat worsens swelling)
  • Keep lips clean — gentle lip balm is fine after 12 hours
  • Sleep with your head elevated on an extra pillow
  • Sleep on your back for 2-3 nights

First Week

  • Swelling peaks at 24-48 hours — don't judge your results yet
  • Any bruising resolves within 5-10 days
  • Avoid strenuous exercise for 48 hours
  • No facials, lip products with active ingredients (retinol, acid) for 1 week
  • No dental work for 2 weeks
  • Your lips may feel firm and uneven initially — this fully settles by week 2

Long-Term Care

  • Final result visible at 2 weeks
  • Lip filler typically lasts 6-12 months
  • The lips have more movement than most areas, so they metabolise filler faster
  • Stay hydrated — hyaluronic acid holds water
  • Use SPF lip balm when outdoors
  • Book top-ups before the filler has fully dissolved for a consistent, natural look

What to Avoid

  • Kissing, hard pressing, or vigorous lip movements for 24 hours
  • Drinking through a straw for 48 hours
  • Hot drinks and spicy food for 24 hours
  • Exercise, saunas, steam rooms for 48 hours
  • Alcohol for 24 hours
  • Lip products with retinol, acid, or active ingredients for 7 days
  • Dental work for 2 weeks

Common Questions

How swollen will my lips get?

Swelling varies — some people get very little, others look significantly swollen for 2-3 days. It always fully resolves. Plan your treatment at least 2 weeks before any important event.

When can I wear lipstick?

Wait 24 hours. Use a new, clean lipstick (or sanitise an existing one with alcohol) to minimise infection risk.

Why do my lips feel lumpy?

Initial firmness is completely normal and settles within 2 weeks as the filler integrates. If lumps persist, Dr Niru can assess at your complimentary follow-up.

What if I get a cold sore?

Lip filler can occasionally trigger a cold sore outbreak if you're prone to them. If you've had cold sores before, mention this at consultation — Dr Niru may recommend prophylactic antivirals.
