Most filler aftercare is about leaving it alone — which is harder than it sounds.
What aftercare do I need after dermal filler? For the first 24 hours avoid heat, saunas, the sea, intense sun, heavy exercise, alcohol and pressing the area; expect swelling and possible bruising for a few days, allow about two weeks for the result to settle, and report severe pain or skin colour change immediately.
The first 24 hours
Leave it alone
Avoid pressing, massaging or manipulating the treated area unless your clinician specifically instructs otherwise, so the product stays where it was placed.
Avoid heat and exertion
No saunas, hot showers, the sea, the pool, intense sun or heavy exercise — heat and raised blood flow can worsen swelling and bruising.
Managing swelling and bruising
Normal and manageable:
- A cool compress applied gently, not pressed
- Sleeping slightly elevated for the first night or two
- Avoiding alcohol for 24 hours, which worsens bruising
- Arnica if your clinician suggests it
- Patience — lips in particular swell noticeably at first
What is normal and when
| Timeframe | What to expect |
|---|---|
| First few hours | Swelling, possible small bumps |
| Days 1–3 | Peak swelling, possible bruising |
| Days 3–7 | Swelling settling, bruises fading |
| ~2 weeks | Final settled result |
| After 2 weeks | Review and any refinement |
The Cleveland Clinic notes typical side effects are mild and short-lived.
Warning signs to report immediately
Rare but urgent
Severe or increasing pain, skin turning white, dusky or mottled, or any vision change should be reported to your clinic immediately.
Why it matters
The medical literature notes vascular occlusion, though rare, needs prompt management — which is why knowing the signs matters.
Aftercare in a tropical climate
Heat is the main factor
Koh Samui’s heat means the usual 24-hour restrictions need a little more planning — treating on a full beach day is not ideal.
Sun protection afterwards
Use daily broad-spectrum protection once the initial period passes, which protects your skin and your result.
Make-up, dental work and flights
Make-up
Avoid make-up on the treated area for the first 12 to 24 hours to reduce infection risk at the injection points.
Dental work and flying
Postpone non-urgent dental work for around two weeks after facial filler, and see our guide to flying after filler.
The two-week rule
Do not judge early
Filler looks different at day two than at day fourteen. Assessing too early leads people to request corrections they do not need.
Then review
A review at about two weeks is when refinement should be considered, not before.
Your filler aftercare routine
A simple routine:
- Avoid pressing or massaging the area unless instructed.
- Skip heat, saunas, sea, sun and heavy exercise for 24 hours.
- Avoid alcohol and make-up on the area for the first day.
- Use a cool compress gently and sleep slightly elevated.
- Report severe pain, skin colour change or vision changes immediately.
- Wait about two weeks before judging the result or requesting changes.

Frequently asked questions
What aftercare do I need after dermal filler?
For 24 hours avoid heat, saunas, the sea, intense sun, heavy exercise, alcohol and pressing the area. Expect swelling for a few days and allow about two weeks to settle.
How long does swelling last after filler?
Swelling typically peaks in the first one to three days and settles over the following week. The final result is usually visible at about two weeks.
Can I exercise after filler?
Wait about 24 hours before heavy exercise, since raised blood flow and heat can worsen swelling and bruising. Gentle walking is generally fine sooner.
What warning signs should I report?
Severe or increasing pain, skin turning white, dusky or mottled, or any vision change should be reported to your clinic immediately, as these can rarely signal a vascular problem.
Can I wear make-up after filler?
Avoid make-up on the treated area for the first 12 to 24 hours to reduce infection risk at the injection points, then resume as normal.
When should I judge my result?
At about two weeks. Filler looks different at day two than at day fourteen, and assessing too early leads to unnecessary requests for correction.
Safety and consultation
Dermal filler is a medical procedure and, like any injectable treatment, carries some risk — common temporary effects can include redness, swelling, bruising or tenderness, and less common reactions are possible. Results vary from person to person, and no specific outcome can be promised. This article is general information, not medical advice.
At LIV Clinic, every treatment begins with an in-person assessment by Dr. Narathai Vichienkalayarut, M.D., who reviews your skin, medical history and goals before recommending a personalized plan. Book a consultation to find out whether this treatment suits you.
