Your Quick Guide to Lip Anatomy

A deep knowledge of lip anatomy not only ensures safe and successful procedures but also allows injectors to create natural, beautiful results that harmonise with the client's facial features.

The lips are complex structures with multiple layers, each serving a unique purpose. Aesthetic injectors must thoroughly understand the anatomy of the lips to navigate the delicate balance between enhancement and overcorrection.


The Layers of Lip Anatomy


Skin and Vermilion

The outermost layer of the lips consists of the skin and the red-coloured tissue known as the vermilion. The vermilion border, which defines the outline of the lips, is a critical area for injectors to focus on. Understanding how to enhance this border while maintaining symmetry is essential for achieving natural-looking results.


Muscles

The muscles in and around the lips play a significant role in lip movement and shape. The orbicularis oris muscle, for example, encircles the mouth and is responsible for lip closure. Injectors need to be aware of these muscles and their functions to ensure that the injected product integrates seamlessly with the natural lip movements.


Mucosa

Inside the lips, there is a mucous membrane known as the oral mucosa. This layer is thinner and more delicate than the vermilion, making it a crucial area to approach with caution during lip injections. Knowledge of the mucosa's anatomy helps prevent complications like vascular occlusion.


Blood Supply

Understanding the vascular supply to the lips is vital to avoid potential complications during injections. The labial artery and its branches provide blood to the lips. Aesthetic injectors must be well-versed in the potential risks and complications associated with vascular occlusion and know how to manage them effectively.


Nerve Endings

Lips are highly innervated, and injectors must be aware of nerve locations to minimise pain and discomfort for their clients. Additionally, knowledge of nerve placement helps prevent inadvertent damage during procedures.















The Cupid's Bow is a term that describes the V-shaped or M-shaped curve that graces the centre of the upper lip. Named for its resemblance to the bow of Cupid, the Roman god of love, this feature holds a special place in facial aesthetics. Understanding the Cupid's Bow anatomy is the first step toward mastering the art of lip enhancement with dermal fillers.


Lip Tubercles

The upper lip tubercles are delicate, rounded prominences situated on the upper lip, just above the vermillion border. They play a pivotal role in shaping the Cupid's Bow and contribute significantly to the overall aesthetics of the lips


Philtrum's Anatomy

The philtrum is the vertical groove that runs from the base of the nose to the centre of the upper lip. The philtrum is situated centrally between the nose and the upper lip. It serves as a bridge, connecting the two facial features and creating the appearance of a well-defined Cupid's Bow.

The philtrum is formed by the convergence of the two philtral columns or ridges. These columns run from the base of the nose to the tubercles or peaks of the Cupid's Bow, defining the central portion of the upper lip.
