Introduction

1. Redness, swelling, and itching; a granular tactile sensation may occur in the skin following hyaluronic acid injection, but this typically resolves spontaneously within one week for most patients. 2. Hyperpigmentation: Patients experiencing this should seek prompt medical evaluation at a hospital; mild cases generally require only timely intervention. 3. Skin hematoma: Mild cases may present as ecchymosis or yellowish discoloration, whereas severe cases may involve overt hematoma formation.

Hyaluronic acid (HA) cheek augmentation can effectively correct facial hollowing; however, this procedure may cause side effects such as facial redness, swelling, and itching. It may also lead to pigment deposition and immune rejection reactions. Therefore, it is strongly recommended that patients choose reputable, large-scale medical institutions for HA injections to minimize potential complications. Below, we address common post-procedural complications associated with hyaluronic acid cheek augmentation.

Side Effects of Hyaluronic Acid Cheek Augmentation

1. Redness, Swelling, and Itching

Following HA injection, patients commonly experience transient swelling, erythema, and pruritus. In most cases, these symptoms subside within one week. Patients with fragile capillaries or sensitive skin may develop mild ecchymosis post-injection; however, this typically resolves spontaneously within a short period. Additionally, some patients may notice a granular tactile sensation at the injection site, which usually disappears spontaneously within approximately one week.

2. Hyperpigmentation

Over-injection of HA may occur in certain cases. If this happens, patients should seek prompt medical evaluation. Mild cases generally require only conservative management, whereas severe over-injection may necessitate surgical removal of the injected material—a technically challenging procedure. Thus, thorough preoperative consultation with the physician is essential. Moreover, superficial injection or inadequate sun protection post-procedure may predispose patients to hyperpigmentation. In such instances, patients are advised to use brightening masks 4–6 times per month for one month.

3. Cutaneous Hematoma

During HA injection, inadvertent vascular injury may result in bleeding. Mild cases may manifest as bruising or yellowish discoloration, while more severe injuries may lead to hematoma or serohematoma formation.

4. Nerve Injury

If local nerves are inadvertently injured during HA injection, corresponding neurological dysfunction may occur. Specifically, injury to the facial nerve may result in ipsilateral oral deviation.

The above outlines the potential complications associated with hyaluronic acid cheek augmentation. We hope this information proves helpful to you.

What are the risks and side effects of hyaluronic acid?

Injecting hyaluronic acid directly into the skin can indeed quickly smooth wrinkles, augment the nasal bridge, or plump the lips, but it is not without risk. Once the needle enters the body, reversible or even irreversible complications may occur. It is recommended to choose a licensed medical facility and a qualified physician, and use products approved by the National Medical Products Administration. Patients should fully disclose their history of allergies, bleeding tendencies, and previous fillers before the procedure.
