How Long Does Lip Filler Swelling Last?

Updated: Jun 10

Dermal fillers are so fabulous for smoothing, plumping, and refreshing the face but swelling afterwards? Yep, that part’s totally normal.


Sometimes it’s just a little puffiness, and sometimes it’s a bit more dramatic especially around the lips!


Let’s walk through it all together: what to expect, how to manage it, and when it might be time to check in.



What Causes Swelling After Fillers?

Swelling is usually a combination of three things:

  • The needle or cannula: Tiny trauma from the injection itself

  • The filler product: Some products attract water, causing puffiness

  • Your immune system: Your body’s lovely little way of saying, “What’s this?”

All of this is totally normal, and your body is just adjusting.



What’s a Normal Swelling Timeline?

Every face is unique but here’s a general guide to what’s expected:


Immediately after treatment

  • Swelling starts right away, especially in the lips and tear troughs.

  • You might also feel a little pressure or firmness.


1–2 days after

  • Swelling usually peaks at 24–48 hours.


3–5 days after

  • Swelling should start settling, and things will begin to smooth out.


7–14 days after

  • Most of the swelling is gone, though deeper areas like tear troughs can take a bit longer to fully settle.

Tip: Always wait 2 full weeks before judging results, that’s when the magic really shows.

Aftercare Tips for Swelling

Here are a few simple things you can do to feel more comfortable while your filler settles:

Immediately After Treatment

  • Apply a cool (not frozen!) compress for 10–15 minutes at a time.

  • Stay upright for at least 4 hours post-treatment.

  • Try to sleep on your back, slightly elevated.


Avoid These for 24–48 Hours

  • Intense workouts or sweating

  • Alcohol

  • Salty food

  • Saunas or steam rooms

  • Makeup (especially on the lips or under eyes)

  • Touching or massaging the treated areas

If you’re not sure whether something is safe, just ask me! I’d rather you double-check than worry.


When to Worry: Red Flags to Watch For

Most swelling is harmless but occasionally, things can go a bit off-track. Please contact your injector immediately if you notice:

  • Pain that increases over time, not decreases

  • Redness or heat that spreads

  • Skin that looks pale, dusky, or patchy (possible vascular occlusion)

  • Fever, chills, or feeling unwell

  • Swelling that gets worse after 3–4 days instead of better

Even if it’s just a niggle or you’re feeling unsure, please message me.



Swelling in Different Areas of the Face

Each area reacts a bit differently:

Lips

  • Swelling can be quite dramatic, especially if it’s your first time!

  • You may even feel slightly uneven or bumpy, this often settles within a week.

Cheeks & Chin

  • Usually milder swelling, may feel firm or “full” for a few days.

Tear Troughs (under-eyes)

  • Swelling tends to last a bit longer here up to 2 weeks.

  • Sleep, salt, and hydration levels can really affect this area.

Nasolabial Folds (smile lines)

  • May feel a little “puffy” or heavy early on but settle quickly.
