Filler Aftercare and What to Avoid

Getting filler is only half the process. What you do in the hours and days that follow plays a real role in how smooth your results look, how quickly swelling settles, and how long the filler lasts. The good news: aftercare is simple once you know the rules.

What to Expect First

Mild swelling, tenderness, redness, or small bruises around the injection points are completely normal. Swelling typically peaks within the first 24 to 48 hours, then steadily settles over the following days. The filler continues to integrate with your tissue over the next one to two weeks, which is when your final result becomes fully visible.

Aftercare: What to Do

Apply cold compresses in 10 minute intervals during the first few hours to reduce swelling. Wrap ice in a clean cloth rather than placing it directly on the skin, and avoid pressing too hard.

Stay well hydrated. Hyaluronic acid fillers draw in water, so drinking plenty helps the product settle smoothly.

Sleep on your back with your head slightly elevated the first night to minimize swelling.

Keep the treated area clean for the first 12 hours.

Use gentle, fragrance-free skincare for the first 24 to 48 hours.

Take paracetamol/acetaminophen if needed for discomfort, rather than ibuprofen or aspirin, unless your provider has cleared otherwise.

Stick to cool or lukewarm water when washing your face.

Once you're past the first 48 hours, wear daily SPF to protect both your results and your skin, and keep up with your regular skincare routine to support the filler's longevity.

What Not to Do

Don't touch, rub, or press on the treated area. For at least 48 hours, avoid massaging or manipulating the injection sites, as this can shift the filler before it has time to settle.

Don't wear makeup for at least 24 hours. Applying makeup too soon raises the risk of irritation or infection at the injection points.

Don't exercise strenuously. Skip intense workouts or cardio for 24 to 48 hours, since raising your heart rate increases blood flow to the face and can worsen swelling and bruising.

Don't expose the area to heat. Avoid saunas, hot tubs, hot showers, and tanning beds for at least 24 to 48 hours. Heat expands blood vessels, which can intensify swelling and bruising and even break the filler down faster.

Don't spend time in direct sun. UV exposure can worsen swelling and bruising. If you have to be outside, wear a hat and protective clothing.

Don't drink alcohol for at least 24 hours. Alcohol thins the blood and increases the likelihood of bruising and swelling.

Don't take blood thinning medications or supplements unless cleared by your provider. Aspirin, ibuprofen, fish oil, vitamin E, and herbal supplements like ginkgo biloba can all raise bruising risk.

Don't book other facial treatments right away. Hold off on facials, chemical peels, laser treatments, or other cosmetic procedures on the treated area until your injector gives the go ahead.

Don't make puckering, sucking, or exaggerated facial movements right after lip filler specifically, as these motions can shift the product before it settles.

When to Call Your Provider

Most side effects are mild and resolve on their own, but reach out to your clinic if you notice pain that worsens instead of improving after the first 48 hours, severe or throbbing pain, or skin that turns white, gray, or unusually blotchy in the treated area. These can be signs of a rarer complication that needs prompt attention.

The Takeaway

Good filler aftercare isn't complicated: be gentle with the area, avoid the handful of things that worsen swelling and bruising, protect your skin from heat and sun, and follow the specific instructions your injector gives you. Do that, and you give your results the best possible chance to settle smoothly and look completely natural.
