How to Apply Lip Liner: A Comprehensive Guide for Small and Full Lips

Posted by Layne Sparks on August 17, 2025

Learning how to apply lip liner is an excellent way to enhance the shape of your lips and extend the wear of your lipstick. It can be especially useful if you have smaller lips and wish to add fullness without resorting to cosmetic procedures. The right application methods can transform your look, improve the precision of your lip colour, and allow you to experiment with different styles. Below is a step-by-step guide on how to apply lip liner to small lips and to all lip shapes in general.

Why Lip Liner Matters

Lip liner is more than just an extra product. It improves colour longevity by preventing lipstick from bleeding or fading. It also helps create a defined, polished edge that frames your lips for a neat finish. If your lips are naturally thin, a well-chosen lip liner can add subtle volume through shading and slightly over-lining. Even if you have full lips, correct application will emphasise your natural shape and keep your lipstick in place all day.

Choosing the Right Lip Liner

Shade Selection

When learning how to apply lip liner, shade selection is crucial. The right shade can either complement your lipstick or be used on its own. A good starting point is to pick a liner that is the same shade as your favourite lipstick. For extra definition, choose one shade deeper than your lipstick. This contrast can make your lip colour pop and create the illusion of greater fullness. If you are new to using liners, neutral or nude colours are usually the easiest to work with.

Formulation

Lip liners come in pencil or retractable formats. Pencil liners typically require sharpening, which ensures a finer point for detailed work. Retractable liners twist up and are easy to use on the go. Some formulas are creamier, gliding on easily, while others are firmer for more controlled application. For small lips, a creamy formula can be helpful if you plan to slightly over-line your natural lip shape since the product will blend more smoothly.

Tools

Although a lip liner can be applied straight from the pencil, having a small lip brush can be an advantage. This tool lets you blend the liner inward so that it merges seamlessly with lipstick or gloss. Concealer brushes can also be used to clean up edges for an immaculate finish.

Pre-Application Prep

An often-overlooked step in understanding how to apply lip liner is the importance of preparing your lips. Smooth, well-hydrated lips will look better once lined and filled with colour.

Exfoliate: Use a gentle lip scrub or a soft toothbrush to buff away dead skin. This helps your liner and lipstick apply without clinging to flaky areas.
Hydrate: Apply a thin layer of lip balm and allow it to absorb. This prevents dryness and encourages a comfortable finish.
Blot: If you have applied too much balm, lightly blot your lips with a tissue to remove any excess product. Too much moisture can cause the lip liner to slip.

Step-by-Step: How to Apply Lip Liner

Find Your Natural Shape
Stand in a well-lit area, preferably with a mirror that shows your entire face. Look closely at the natural outline of your lips. Identify the highest points of your cupid’s bow, the corners of your mouth, and the centre of your bottom lip.
Outline the Cupid’s Bow
Begin with the upper lip. Lightly trace the cupid’s bow using short, feathery strokes. This part of the lip adds definition to your overall look. If you have small lips, you can create the illusion of fullness by tracing just above your natural lip line, but only by a millimetre or two.
Line the Corners
Move from the corners of your mouth toward the centre. Using short strokes will help you avoid an uneven or jagged line. Connect your initial outline of the cupid’s bow to the corners.
Shape the Bottom Lip
Proceed to the bottom lip. Identify the centre point below your lips, which is often the plumpest area. Outline this centre first and then work outward to each corner. Keep your strokes light for precision.
Check for Symmetry
Step back or tilt your chin slightly. Ensure both sides of your top lip match and that your bottom lip looks balanced. If one side appears off, you can add a touch more liner to correct the shape.
Fill In
Once you have the perfect outline, consider filling in the rest of your lips with the liner. This creates a base that can make your lipstick last longer. It also ensures there is no visible gap between your lipstick and liner. For small lips, filling in can add dimension by preventing a stark line around the edge.
Apply Lipstick or Gloss
After filling in your lips, apply your chosen lipstick or gloss directly on top. Start at the centre of the lips and work outward. If you have used a darker liner, blend it gently with a lip brush before applying the lipstick to prevent harsh lines. On the other hand, if you want a sharp, defined edge, apply your lipstick carefully without fully blending the liner.
Clean Up
Use a small concealer brush with a tiny bit of foundation or concealer around the outer edges of your lips. This step covers any mistakes and accentuates the crisp outline.

Specific Tips for Small Lips

If you are looking for advice on how to apply lip liner to small lips, the approach above is ideal, but add the following tweaks:

Slight Over-Lining: Go a millimetre beyond your natural lip line, focusing on the cupid’s bow and the centre of your bottom lip. Avoid overextending at the corners to maintain a natural look.
Light to Dark Blending: Choose a nude or medium-toned shade that is one step deeper than your natural lip colour. After outlining, fill in your lips and use a slightly lighter lipstick in the centre. This contrast adds the illusion of volume.
Gloss Highlight: Add a dab of gloss in the centre of your lips to reflect light. This trick draws attention to the plumpest part of your lips.

Maintaining Your Lip Liner Look

Once you have successfully applied your lip liner, aim to maintain your look throughout the day. Carry a small mirror and your lip liner or lipstick for any touch-ups after meals or drinks. A quick re-outline can keep your lips looking fresh. If your chosen lipstick fades, reapply a layer over the existing liner, blending as needed. Exfoliating and moisturising regularly will also help your lips stay in prime condition.

Final Thoughts

Mastering how to apply lip liner does not require advanced skills. With the right prep, careful product selection, and patient application, anyone can achieve a perfectly outlined pout. If you have small lips and wish to create a fuller look, a little over-lining and clever shading can make a noticeable difference. For those with naturally full lips, precise application will maintain a tidy finish for any lip colour. Experiment with various shades and techniques to find what complements your style best. Lip liner is a versatile tool that can enhance your natural shape or allow you to experiment with new looks.
