How many days does the swelling last? How to determine whether it is an abnormal reaction?
This article will give you a detailed analysis of the lip swelling process after filling, recovery rules and scientific care methods to help you feel at ease and beautiful.
Why do lips swell after filling?
Lips are rich in blood vessels and nerves, the skin is thin, sensitive tissue, so in the injection of hyaluronic acid after a short-term swelling is a normal physiological reaction.
The main causes of swelling include:
Injection stimulation and minimally invasive reaction: hyaluronic acid is injected into the dermis or submucosa through a needle or blunt needle, and local tissues are slightly edematous due to mechanical stimulation.
The hydrophilicity of hyaluronic acid: hyaluronic acid itself will absorb water expansion, so that lips temporarily become more full.
Mild inflammation: the body after the injection will start self-repair mechanisms, the release of inflammatory factors, resulting in local redness.
Therefore, mild to moderate swelling is normal after surgery-it is a natural process of skin repair and adaptation.
The degree and time regularity of normal swelling

Usually, the swelling of the lips goes through a process from noticeable to gradual resolution.
Within 1 to 2 hours after surgery, there will be mild local fever and swelling, and the lips will appear more puffy than expected. Don't worry, you can ease the discomfort by icing for 10 to 15 minutes.
The most obvious stage of swelling was within 24 hours after operation. At this point the lips look larger than they should, and may be accompanied by mild tingling or pin-eye redness.
It is recommended to avoid hot compresses, do not touch, do not eat spicy or too hot food, in order to prevent increased swelling.
After 2-3 days, the swelling will be reduced, the lips will become softer, and the lines will begin to come naturally.
By 5 to 7 days after surgery, most of the patients had returned to near-ideal lip shape and were able to apply makeup and eat normally.
After 10 to 14 days, the lips are fully formed, and they look and feel their best.
Overall, the swelling subsided by about 80% within 3 to 5 days and returned to normal after 10 days.
It is important to be patient and take proper care during this time, as everyone's metabolic rate and physical differences will affect the recovery rate.
How to distinguish normal swelling from abnormal reaction?
Swelling of the lip after injection is a normal physiological phenomenon, but if the swelling lasts too long or accompanied by other discomfort, it is necessary to raise the alarm.
Under normal circumstances, only mild lip swelling, tightness or slight redness, does not affect life, nor will it last long. It usually takes 3 to 7 days to recover.
Anomalies include:
- The swelling persisted for more than 10 days
- Lip color appears white, purple or mottled, accompanied by severe pain;
- Local formation of hard lumps, nodules, feel a foreign body;
- Lip appear high fever, redness spread, and even have pus exudation.
These symptoms may indicate inflammation, infection, or blockage of the blood vessels and should be reported to your doctor immediately.
Hyaluronidase dissolution, anti-inflammatory drugs, antihistamines, or antibiotics are usually prescribed as appropriate.
In short:
If it is only slightly swollen, tight, and tingly-that is a normal recovery;
Seek medical attention immediately if color changes, severe pain, or persistent pain occur.
Factors influencing the degree of swelling

The swelling of the lips after filling is not random and is closely related to several factors:
Techniques and methods of injection:
Experienced doctors can accurately grasp the level and intensity of injection to reduce trauma. In general, blunt needles are less invasive and less swollen than sharp needles.
Dose and depth of injection:
The larger the injection volume, the deeper the level, the more obvious the tissue expansion, and the heavier the swelling naturally. It is recommended to start with a small amount and work your way up.
Individual Differences:
The patients with sensitive constitution and edematous constitution had more obvious postoperative reaction and longer recovery time.
Hyaluronic acid brand and texture:
Different brands, different molecular structures and different degrees of cross-linking, hydrophilic differences will lead to different degrees of swelling. Soft hyaluronic acid is better for the lips because it is less swollen.
