Beauty is often associated with the eye of the beholder, but what if there is a mathematical formula behind it? The iconic artist Leonardo da Vinci was not only a virtuoso painter, but also a scientist and anatomist. His interest in the human form led him to explore the Golden Ratio, a mathematical principle that determines what we perceive as aesthetically pleasing. Interestingly, this proportional section has also been applied to the field of aesthetics, particularly in achieving perfect lips using dermal fillers.

The golden section and your lips

The golden ratio, also called the golden ratio, golden quotient, or divine proportion, is a mathematical concept that states that the most harmonious and aesthetically pleasing proportion between two objects is about 1:1.618. This principle has been known for centuries and originated with the ancient Greek mathematician Euclid. Leonardo da Vinci emphasised it further in his work “Divine Proportion”, described by the Italian mathematician Luca Pacioli.

In nature, the golden ratio is seen in abundance. It is present in various forms. It can be spotted in the shells of molluscs, such as snails and oysters. The section is present in the leaves of some plants and elements of their anatomy. It can even be found in human anatomy.

Adherence to the Golden Section also plays an important role in lip shape. Ideally, the lower lip should be about 1.618 times larger than the upper. Additionally, the upper lip should protrude outward about 1.618 more than the lower lip when viewed from a lateral perspective. And another important detail is that the lips should be 1.618 times the width of the nose.

The use of the Golden Section in lip shaping

Hyaluronic lip fillers are becoming increasingly popular for achieving full and defined lips. Achieving the perfect lip shape takes not only professional skill, but also art. Understanding the Golden Section is essential for the injector as it allows them to enhance a person’s natural beauty by adding just the right amount of filter to achieve harmony and balance for the entire face.

The importance of adhering to the Golden Section becomes apparent when considering the risk of excessive lip augmentation, which can lead to an unnatural and undesirable appearance known as “duck lips.” Therefore, it is essential to choose a trusted and experienced dermatologist who has sufficient in-depth knowledge of facial anatomy and principles of proportion.

Tips to achieve the perfect lip shape

Before you decide on shaping your lips with a filler, it’s important to consider some key points to ensure satisfying results:

Choose the right clinic:
Research and choose a professional who has experience, such as a dermatologist or plastic surgeon. This will ensure you get the right amount of filter safely and effectively.

Set realistic expectations: although fillers can increase lip volume and improve lip shape, keep in mind that there are limits to what they can achieve. Realistic expectations will help you avoid disappointment and achieve a natural and beautiful look.

Understand the basic anatomy of the lips: Familiarize yourself with the basic terms related to the anatomy of the lips. This knowledge will help you communicate effectively with your dermatologist or surgeon and clearly describe your desired results.
