Lip injections are a non-surgical treatment used to enhance lip volume, refine contour, and restore definition that may diminish over time. Some individuals seek subtle fullness, while others wish to improve balance between the upper and lower lips or enhance the natural outline of the lip border. When performed conservatively, lip injections can create a more defined yet natural appearance that complements the surrounding facial features.
At McKinnon Plastic Surgery, injectable treatments are offered within a practice focused on facial anatomy and structural balance. The practice is led by Dr. McKay McKinnon, a plastic surgeon known for his work in craniofacial and reconstructive surgery. His extensive background in facial structure informs the treatment philosophy and clinical standards guiding aesthetic services provided at the Chicago and Coral Gables offices.
What Are Lip Injections?
Lip injections typically involve the use of hyaluronic acid–based dermal fillers to add volume and shape to the lips. Hyaluronic acid is a substance naturally present in the body that helps maintain skin hydration and fullness.
When carefully placed, dermal fillers can:
- Add subtle volume to the lips
- Improve definition along the lip border
- Enhance symmetry between the upper and lower lip
- Soften fine lines around the mouth
Unlike permanent procedures, hyaluronic acid fillers are temporary and gradually absorbed by the body over time.
What Lip Injections Can Improve
Lip injections are often used to address concerns related to both lip shape and age-related changes. Over time, the lips may gradually lose volume and definition, and the border of the lips can become less distinct. Some individuals also naturally have thinner lips or asymmetry between the upper and lower lip.
Injectable fillers can help improve:
- Naturally thin lips
- Gradual volume loss that occurs with aging
- Asymmetry between the upper and lower lip
- Reduced definition along the lip border
- Fine lines that form around the mouth
Treatment planning focuses on maintaining natural proportions so that the lips remain balanced with the surrounding facial features.
What To Expect During Treatment
Lip injections are typically performed during a short office visit. Before treatment begins, a topical numbing cream may be applied to help minimize discomfort.
During the procedure, small amounts of filler are carefully placed into specific areas of the lips using a fine needle or cannula. The injector evaluates the lips throughout the treatment to ensure even distribution and natural contour. Because the lips are highly mobile structures, precise placement is important to preserve normal movement and expression.
Most appointments take less than an hour, and patients are generally able to leave the office shortly afterward.
How Long Lip Injection Results Last
Hyaluronic acid fillers gradually break down as the body metabolizes the material over time. Because of this, lip injections are considered a temporary treatment.
For most patients, results last approximately six to twelve months, although this can vary depending on the product used, the amount injected, and individual metabolic factors. Patients who wish to maintain their results often choose periodic maintenance treatments once the effects begin to fade.
Who Is A Candidate For Lip Injections?
Lip injections may be appropriate for individuals who:
- Want to add subtle fullness to the lips
- Notice volume loss related to aging
- Wish to improve lip symmetry or contour
- Prefer a non-surgical aesthetic treatment
A consultation allows the clinical team at McKinnon Plastic Surgery to evaluate lip structure and determine whether injectable treatment is appropriate.
Why Choose McKinnon Plastic Surgery For Lip Injections?
Lip injections require precise knowledge of facial anatomy, particularly the muscles and structures surrounding the mouth. Small variations in injection placement can significantly affect lip shape, symmetry, and movement, making careful technique essential for natural-looking results.
McKinnon Plastic Surgery is led by Dr. McKinnon, a board-certified plastic surgeon who completed specialized craniofacial fellowship training in Paris under Dr. Paul Tessier, a pioneer in modern craniofacial surgery. His surgical career has focused extensively on complex facial procedures where accurate understanding of facial structure and movement is critical.
That background informs the standards used for aesthetic treatments within the practice. Lip injections are planned with attention to facial balance and proportion, emphasizing subtle enhancement rather than exaggerated cosmetic results.
