Hyaluronic acid has gained significant popularity in cosmetic procedures for its ability to reduce wrinkles and pigmentation while delaying aging. It is used for lip augmentation, rhinoplasty, and breast enhancement. However, some individuals experience facial redness and swelling after injections.Why does facial swelling occur after hyaluronic acid injections? 1. Normal physiological response After injection, the process of filling sunken areas takes time. Extensive injections can also cause swelling. Facial puffiness during recovery is normal. Some individuals may experience redness, hardness, and mild bruising at the injection site on the first day. Swelling typically subsides within 2-3 days, with results stabilizing after one week.
2. Over-injection
Some individuals may receive excessive hyaluronic acid in a single session to achieve more dramatic results. Since hyaluronic acid has strong water-absorbing properties, over-injection can cause facial swelling and a plastic-like appearance due to overfilling. It is crucial to strictly control the injection volume, never exceeding 100 milliliters per session.
3. Low-Quality Hyaluronic Acid
Unregulated clinics may offer cheap hyaluronic acid to attract customers. However, you get what you pay for—low-cost products may be counterfeit or inferior, leading to facial swelling.
What to do if your face swells after hyaluronic acid injection?
1. Use hyaluronidase appropriately
If swelling results from excessive single-session injection, visit a reputable hospital for hyaluronidase to dissolve the hyaluronic acid in your body. Hyaluronic acid is highly water-absorbent and is easily absorbed and degraded by the body.
2. Wait for swelling to subside
Hyaluronic acid injections may cause minor capillary rupture, leading to congestion and edema—a normal physiological response typically occurring within two hours post-injection. Swelling starts mildly and peaks around 20 hours later. Avoid hot or cold compresses, as they accelerate hyaluronic acid breakdown. Swelling usually resolves within three days with patience.
3. Remove counterfeit hyaluronic acid material
If injected at unlicensed clinics with unapproved brands, the injected material may cause facial swelling accompanied by localized bruising. Seek immediate medical attention to remove counterfeit hyaluronic acid and undergo necessary repair procedures.
Important Reminder
While hyaluronic acid injection is a straightforward procedure, it is crucial to ensure the use of certified materials. Post-injection care is essential: avoid saunas for one week and refrain from taking aspirin or medications that promote blood circulation and disperse blood stasis. Maintain a light diet, avoiding spicy or irritating foods such as chili peppers, scallions, garlic, beef, lamb, mutton, or seafood.
