The Anatomy of the Lip
Lip injections are becoming increasingly popular. In fact, clinics across the UK have reportedly experienced increases of up to 70% in enquiries about lip fillers.
Although there have been rumours that lip icon Kylie Jenner received lip injections before the age of 18, 111 Harley St. does not recommend dermal fillers for anyone under the age of 21. Ideally, patients should wait until they are at least 25 before considering lip enhancement treatments.
What Types of Lip Injections Are There?
Lip injections vary in their longevity and are used to alter the size, volume and shape of the lips.
The most commonly used fillers contain hyaluronic acid, a substance that occurs naturally in the body. Hyaluronic acid fillers are often preferred because their effects can be adjusted to achieve a more controlled, natural-looking result.
Results typically last between six and nine months, depending on the product used and individual factors. Patients commonly receive 1 ml of filler, although the appropriate amount should be discussed with a qualified practitioner during a consultation.
Different brands are available, with Restylane and Juvederm among the commonly used hyaluronic acid fillers.
Lip Injection Techniques
Achieving the desired result involves more than simply injecting filler into the lips. The outcome depends on several factors, including the patient’s natural lip size and shape, facial proportions and the length of the philtrum—the area between the base of the nose and the upper lip.
For example, creating additional volume can be more challenging in patients with a longer philtrum. Excessive filler may cause the upper lip to project outwards, potentially creating an unnatural, wedge-shaped appearance.
Choosing the right lip filler technique is therefore essential. Treatment should be tailored to each individual’s lip anatomy and aesthetic goals. A qualified practitioner can assess the lips and determine the appropriate injection points and technique.
Although many people assume that filler is injected directly into the body of the lip, practitioners may also inject along the vermilion border—the outline between the lips and the surrounding skin. This technique can help define the lip contour and enhance features such as the Cupid’s bow.
The most appropriate technique depends on the individual’s anatomy, desired outcome and the practitioner’s clinical assessment.
Why Lip Anatomy Matters
Understanding lip anatomy is important when planning lip enhancement. Factors such as the natural lip shape, the vermilion border, the Cupid’s bow and the proportions of the upper and lower lips can all influence the final result.
A personalised approach helps practitioners determine how to enhance lip definition and volume while maintaining facial balance and natural-looking proportions.
