When Does Swelling Go Down After Lip Fillers

Lip fillers have become increasingly popular for those seeking plump, youthful lips. However, like any cosmetic procedure, it’s essential to understand what to expect during the recovery process, including the inevitable swelling that follows. If you’re wondering, “When does swelling go down after lip fillers?” this article provides insights into the timeline of post-filler swelling, tips to reduce it, and what you can anticipate as your lips transform.

Understanding Lip Filler Swelling

Swelling is a common side effect of lip filler injections. It occurs as a natural response to the injection process and the introduction of a foreign substance into the lips. While it can be a bit uncomfortable, swelling is a normal and expected part of the healing process. Here’s what you need to know:

Immediate Swelling

Right after the lip filler procedure, you can expect significant swelling. This is due to the injection itself and typically peaks within the first 24 to 48 hours.

Subacute Swelling

After the initial swelling subsides, you may experience a subacute phase of swelling. This can last for a few days to a week, depending on individual factors and the type of filler used.

Residual Swelling

Some residual swelling may linger for a few weeks, but it is usually subtle and not as noticeable as the initial post-injection swelling.

Timeline of Swelling After Lip Fillers

The duration of swelling after lip fillers can vary from person to person. Several factors influence how quickly your swelling resolves, including:

Individual Healing

Everyone’s body heals at a different rate, so your experience may differ from others.

Type of Filler

The type of filler used can affect the extent and duration of swelling. Hyaluronic acid fillers are common and generally associated with less swelling compared to other options.

Injection Technique

The skill and technique of your injector play a crucial role. A skilled injector can minimize trauma and reduce swelling.

Other Side Effects


Bruising at the injection site is another common side effect of lip filler injections. It occurs because the needle used during the procedure may penetrate small blood vessels beneath the skin’s surface. As a result, you might notice areas of discoloration or bruising around the lips. The duration of bruising can vary widely from a few days to a week or more, depending on individual factors and the extent of the bruise.

Tenderness and Discomfort

It’s entirely normal to experience tenderness and discomfort at the injection sites for a few days after the procedure. This discomfort is usually mild and short-lived, lasting a few days at most. It’s part of the body’s natural response to the injection process and the filler settling into place.

Redness and Irritation

You may notice redness and slight irritation at the injection sites immediately after the procedure. This is typically temporary and should subside within a day or two. It’s a normal part of the healing process as your body adjusts to the presence of the filler.

Lumpiness or Unevenness

Some individuals might notice small lumps or unevenness in the treated area. This can occur as the filler settles and integrates with your natural tissues. These minor irregularities are generally temporary and should resolve within a week or two as the filler distributes evenly.

Itching or Tingling

Itching or tingling sensations at the injection sites are relatively common as the filler settles into place. These sensations are generally mild and temporary, and they’re a sign that your body is adjusting to the filler.

Allergic Reactions

While rare, allergic reactions to the filler or anesthesia used during the procedure can occur. Symptoms may include extreme swelling, itching, hives, or difficulty breathing. Allergic reactions require immediate medical attention and can last until appropriate treatment is administered.


Mild asymmetry is common during the initial healing phase. Your lips may not appear perfectly balanced immediately after the procedure. However, this usually improves as swelling subsides and the filler settles into its final shape, providing you with the desired result.

Tips to Reduce Swelling After Lip Fillers

While some swelling is inevitable, you can take steps to minimize its impact and promote faster healing:

Cold Compresses

Applying cold compresses to your lips in the first 24 hours can help reduce initial swelling. Be gentle and avoid direct contact with ice.

Arnica Gel or Supplements

Arnica is a natural remedy known for its anti-inflammatory properties. Some people find arnica gel or supplements helpful in reducing swelling and bruising.

Avoid Blood Thinners

In the days leading up to your appointment, avoid blood-thinning medications, supplements, and alcohol, as they can exacerbate swelling and bruising.


Sleeping with your head slightly elevated can help reduce swelling overnight.


Most importantly, have patience. Swelling will gradually subside over time.

What to Expect During the Healing Process

As your lips heal and swelling goes down, you’ll notice a transformation in their appearance. Here’s a rough timeline of what to expect:

Week 1

Swelling is at its peak during the first few days. Your lips may look fuller than desired, but this will gradually improve.

Week 2

Most of the initial swelling should have subsided by this point, revealing your final results.

Weeks 3-4

Any remaining subtle swelling and minor irregularities will continue to improve, and your lips will settle into their final shape.

When to Contact Your Injector

While swelling is a normal part of the lip filler process, there are instances where you should contact your injector:

Severe or Prolonged Swelling

If swelling is severe, painful, or persists beyond the expected timeline, it’s essential to consult your injector to rule out any complications.

Allergic Reactions

If you experience symptoms of an allergic reaction, such as extreme swelling, itching, or hives, seek immediate medical attention.


Swelling after lip filler injections is temporary and varies in duration from person to person. Understanding the timeline of swelling, practicing patience, and following tips to reduce it can help you navigate the healing process with confidence. Remember that the final results of your lip fillers will become more apparent as the swelling subsides, leaving you with fuller, beautiful lips that enhance your natural beauty.
