What should you know about uneven cheek filler?

After cheek filler, one side may look fuller because swelling is not identical on both sides. Bruising, pressure from sleeping, and the timing of the injection can also make the cheeks appear mismatched during early healing. A difference that remains after the expected settling period may relate to product position, volume, facial asymmetry that was present before treatment, or a small lump under the skin.

Cheek filler is often made with hyaluronic acid, a gel that adds volume beneath the skin. You can read more about [Hyaluronic Acid Filler](/materials/hyaluronic-acid-filler/). Do not massage, press, or add more product unless your clinician specifically advises it.

Take clear photographs in the same lighting and keep a note of when swelling, tenderness, colour change, or firmness began. Follow the aftercare instructions you were given, avoid unnecessary pressure on the treated cheeks, and arrange a review if the contour remains uneven or a firm area is developing. A clinician can examine the tissue and discuss observation, adjustment, or another appropriate option.

Contact the injector promptly for increasing pain, marked swelling, skin that becomes pale or dusky, unusual coolness, spreading redness, or changes in vision. Seek urgent medical care for severe pain, sudden visual symptoms, weakness, confusion, or trouble speaking. These symptoms need assessment rather than home treatment.

Ask what degree of asymmetry is expected at your stage of healing, whether the product and injection sites can explain the difference, and which symptoms should trigger same-day review. Ask before using massage, heat, or any product intended to dissolve filler.
