How to Inject Small Lips: Advanced Lip Filler Techniques

For Natural Enhancement

The Challenge of Small Lip Treatment

How do you treat small/thin lips to get a good result as well as manage the patient’s expectations. The key is to get a good result without downgrading your patients while understanding that you can always try again in the future to add more volume in a more controlled way.

Small lips present unique challenges that require specific lip filler techniques and careful consideration of natural lip enhancement principles. The approach differs significantly from treating larger lips, requiring practitioners to understand both the technical aspects and the aesthetic goals that create beautiful, proportionate results.

Pre-Treatment Assessment: The Foundation of Success

It can be helpful before you start just to ask yourself when you move the lip what makes your patient prettier because this gives you an idea about where volume needs to be. This fundamental question guides your entire treatment approach and helps establish realistic expectations with your patient.

When assessing small lips, focus on identifying areas where enhancement will create the most aesthetic impact. The goal isn’t simply to make lips bigger, but to create proportion and beauty that enhances the patient’s natural features while maintaining authenticity.

Vertical vs. Horizontal Injection Techniques

There are two primary types of injections you might use when treating small lips with a needle. Understanding the difference between these approaches is crucial for achieving optimal results.

Horizontal injections are going to add mostly volume. This technique focuses on increasing the overall fullness of the lip but may not provide the height and projection that small lips often need most.

Vertical injections will add volume and a bit more height. They may be a particularly useful technique to keep in your arsenal when treating small lips because they address both volume deficiency and the need for better projection and definition.

The Importance of Vermillion Border Preservation

Because the vermillion border is very well defined in the patient in the image example, there’s no need to work on enhancing it. The focus should be on preserving this natural landmark. This means not entering close to the border but instead working just below it to create a little bit of projection underneath the Glogau-Klein point.

This preservation principle is crucial in small lip treatment because these patients often have naturally well-defined features that should be enhanced rather than altered. Working too close to existing anatomical landmarks can disrupt the natural beauty that already exists.

Starting with Vertical Injections: The Strategic Approach

Before beginning horizontal volume work, it’s often beneficial to start with a vertical injection because this is where you’ll get most of your early wins in terms of vertical height, which is what small lip patients typically want most of all.

Vertical injections are harder to perform in thinner lips because you have less space to work with. Imagine if the patient’s natural lip was much fuller – you’d have more space for maneuvering. This spatial limitation is one of the key challenges in small lip treatment.

Technical Modifications for Small Lips

One technique you can use with your patient is to rotate their lip upward, which gives you a little bit more space to work. This simple manipulation creates better access for vertical injections while providing better visualization of your injection site.

However, be aware that as you rotate the lip upward, the superior labial artery is also being pulled out of its natural position. You can sometimes feel it underneath or see it, and it’s always worth having a look. You’ll sometimes see it pulsating, which helps you identify its location and avoid it during injection.

If you’re in the right level, you should be above the artery anyway, so always be aware of your injection depth. This depth awareness becomes even more critical when working with small lips where space is limited.

Needle Modification Techniques

If you’re going to perform a vertical injection, one of the hardest things is the fact that your needle is quite straight in comparison with the curvature of the lip. You can do something very simple which is put a little kink in the top of the needle, and that makes it a little bit easier to follow the natural lip contour.

You can create a couple of kinks to basically curve the needle so that you have the ability to follow that curve of the lip a little bit more easily. This modification can be done with a sterile swab that is soaked in the cleansing agent, then clamping it and curving it with a pair of pliers to create the desired shape.

Injection Depth and Bevel Positioning

The reason that the bevel should be positioned downward is that as you’re following the lip’s natural arc, you don’t want filler to bubble up to the surface, which is a known outcome of this technique. You’ll often see little surface bubbles of product, and you need to massage them until they disappear.

By positioning the bevel appropriately and maintaining proper depth, you reduce the risk of surface irregularities while achieving the desired volume and projection enhancement.

Critical Insertion Point Technique

The insertion point is very important to get right when treating small lips. If you go through the white part of the lip, which is how some techniques were performed in the past, you go straight through where the arteries are located, resulting in significantly more bleeding. This older approach would literally cause blood to trickle down the patient’s face.

The modern approach focuses on decreasing the risk of excessive swelling and bruising, which means injection depth becomes the most important consideration. Depth control represents the most critical aspect of lip injection technique.

Optimal Injection Placement

Look very closely at the surface of the lip. You have the white lip and the pink lip with a boundary where they meet. Never go through even the first part of this boundary as it’s very sensitive. Instead, inject just where the pink is starting and stay in the most superficial plane possible while still achieving your desired results.

This placement strategy ensures you’re working in the safest zone while maximizing the aesthetic impact of your treatment.

Volume Distribution Strategy

When performing the actual injection, start by pricking the skin just where the pink lip begins. Perform a depth check and control the depth of your needle throughout the entire injection process. You don’t want to go deeper as you advance the needle.

Many injectors don’t aspirate in this area, and while it may not be particularly risky to skip aspiration if you’ve followed all other safety protocols, it should be part of your standard technique. Aspiration becomes muscle memory and adds an extra layer of safety to your procedure.

Managing Multiple Injection Points

If you’re planning to perform two vertical injections, it’s often beneficial to use the same entry point to decrease the amount of swelling and trauma. This approach minimizes tissue disruption while achieving your desired volume distribution.

You might notice that product tracks along the vermillion border as it’s coming out, which demonstrates that not all product stays exactly where you place it. This is normal and shows how filler flows within tissue, which may influence your subsequent injection decisions.

The Sandwich Technique Application

For small lips that have a combination of creases alongside volume loss, consider using a sandwich-like technique. You can inject the base of any folds with deeper injections, treat the mid-layer with supportive volume, and then address the most superficial aspects gently to remove deeper elements of any surface irregularities.

This layered approach ensures comprehensive treatment while maintaining natural lip architecture and movement.

Post-Injection Sculpting

It’s important to perform what can be called sculpting massage after injection so that you’re getting the shape you want rather than relying on the natural path that filler flows. Filler naturally flows to low-pressure points within the lip, which aren’t always exactly where you want the volume to be distributed.

A gentle squeeze to create the desired shape often produces better results and eliminates any distracting lumps or bumps that might develop from uneven product distribution.

Understanding Immediate vs. Final Results

One of the challenges for injectors is distinguishing between what you see as actual product versus swelling. When you first inject, you have a rough guide because you can see the product placement. However, within 30 seconds, much of what you observe is actually swelling rather than the product itself.

You need to make a mental note of how the lips appeared immediately after injection and then assess based on expected swelling patterns. This skill develops with experience and helps you avoid over-correction during the treatment session.

Conclusion: Mastering Small Lip Enhancement

Successful small lip treatment requires understanding the unique challenges these cases present and adapting your technique accordingly. The focus should be on creating height and projection in the central third of the lip while preserving natural details and avoiding over-treatment of lateral areas.

By mastering vertical injection techniques, understanding proper depth control, and using appropriate volume distribution strategies, you can achieve beautiful, natural-looking results that enhance your patients’ existing features rather than creating an artificial appearance.

Remember that with small lips, less is often more, and you can always add additional volume in future sessions as needed. The goal is natural enhancement that makes patients feel more confident while maintaining their authentic appearance.
