Lip Filler Guide – Cupid's Bow, Ratios & Hydration Tips
Lip filler has become one of the most requested cosmetic treatments worldwide. Whether you are seeking subtle enhancement or a more dramatic look, modern dermal filler techniques allow for personalised results. If you are considering lip filler, it’s helpful to understand the key features that influence how lips look and how skilled practitioners approach each area.
The Cupid’s Bow – Height, Shape & Sharpness
The Cupid’s bow is the gentle “M” shape in the centre of the upper lip. Its height and definition play a major role in how youthful and attractive the lips appear. A sharply defined Cupid’s bow creates elegance and symmetry, while a softer bow can give a more natural, understated look.
Taylor Swift is often referenced for her beautifully defined Cupid’s bow – sharp, symmetrical, and balanced with the rest of her features. Lip filler can be used to subtly enhance or sharpen this area, adding definition without over-volumising.
The Vermillion Border – Supporting Lip Projection
The vermillion border is the line where the pink of the lips meets the surrounding skin. A well-defined border provides structure, prevents lipstick from “bleeding,” and enhances natural lip projection. When filler is carefully placed along the vermillion border, it gives lips a lifted appearance and helps them appear fuller without necessarily adding volume.
Lip Ratios – Finding Balance
One of the most important factors in lip aesthetics is the ratio between the upper and lower lip. Different ratios create different impressions:
1:1 Ratio – A balanced look, where the top and bottom lips are almost equal in size. Scarlett Johansson is a good example of naturally proportioned 1:1 lips.
1:1.6 Ratio – Often seen as the “golden ratio,” where the bottom lip is slightly fuller than the top. Angelina Jolie’s iconic lips are a classic 1:1.6 proportion.
1:2 Ratio – A more dramatic look, with a significantly fuller lower lip. Kylie Jenner’s lip shape often reflects this style, which can give a youthful, striking appearance.
Your practitioner will recommend the ratio that works best with your facial structure, maintaining natural balance while achieving your desired look.
Lip Height & Width – Central vs. Corner Balance
Another consideration is the vertical height of the lips compared to the corners of the mouth. Some individuals, such as Julia Roberts, are known for having wider, centrally focused lips that extend toward the edges of the mouth. Others may have fuller volume only in the central area, giving a more heart-shaped effect. Lip filler can be used to refine this balance by either accentuating central fullness or extending subtle volume toward the corners for a broader smile.
Volume & Hydration – The Role of Hyaluronic Acid
Modern lip fillers are made with hyaluronic acid (HA), a substance naturally found in the skin. HA has a unique ability to hold water, which not only adds volume but also improves hydration. This is why treated lips often feel softer, smoother, and more supple after filler. The result is not just added fullness but also healthier-looking lips with restored plumpness and hydration.
Final Thoughts
Getting started with lip filler is not about creating “one-size-fits-all” lips – it’s about enhancing your natural features. By understanding elements such as the Cupid’s bow, vermillion border, lip ratios, and overall proportions, you and your practitioner can work together to design results that are elegant, balanced, and tailored to you.
For new lipfiller patients it is good to examine lips, celebrities or your friends and start thinking about what sort of lips may suit your appearance
