At Ethos Aesthetics + Wellness, Dr. Hardik Soni is renowned for his artistic eye and deft hands when it comes to lip enhancement procedures.

With years of experience injecting and perfecting lip fillers, Dr. Soni provides safe, natural-looking results to patients through bespoke treatment plans.

In this comprehensive guide, we explore everything you need to know about lip fillers, from what they contain and how they work to the tools and techniques involved in the injection process.

You’ll also discover expert tips from Dr. Soni himself on achieving beautiful, subtle lip enhancement.

What Are Lip Fillers and How Do They Work?

Lip fillers are injectable products containing hyaluronic acid, a naturally occurring substance in the body that provides volume to the skin. When expertly injected into the lips, fillers add fullness and definition to a flat or thinning pout.

The hyaluronic acid microspheres in the filler attach to water molecules and expand, creating a plumping effect. Results from lip fillers are temporary, lasting 6-12 months before the filler is absorbed by the body.

According to Dr. Soni, “Hyaluronic acid fillers like Juvederm and Restylane are the gold standard in lip enhancements today. With specialized techniques, I’m able to shape and define the lips for a soft, pillowy look that appears natural.”

Essential Tools and Materials for Lip Filler Injections

Administering lip filler injections requires an artistic eye and a steady hand. The following tools allow for safe, controlled injections:


The choice of needle size may vary depending on the treatment area and the intended outcome:

  • 30G Needles: These are extremely fine and ideal for injecting into detailed areas of the lips, allowing for precise work.
  • 27G Needles: These needles, which are among the finest available, have greater control and comfort during the procedure.
  • 25G Needles: These are used for administering thicker fillers, smoothly delivering the product for effective volumizing effects.

As Dr. Soni notes, “Needle size impacts the injection experience and outcome. After assessing the lips and goals, I’ll select the optimal needle for precision and painless treatment.”


Beyond needles, the use of a cannula can also be a significant aspect of the injection process. A cannula is a slender, flexible tube inserted through a needle to deliver the filler. After the cannula is positioned, the initial needle is removed.


Syringes precisely hold and dispense filler material. 1ml syringes are commonly used. The needle attaches to the tip of the syringe barrel.


Topical numbing creams or injected nerve blocks may be used to maximize patient comfort during treatment.

Marking Pens

Specialized markers outline injection points on the lip area.


Cleaning products like chlorhexidine ensure the treatment area is sterile.

How to Properly Inject Lip Fillers

Administering lip fillers takes technical skill, artistry, and experience. Here is an overview of Dr. Soni’s injection process:


The lips and surrounding area are thoroughly cleansed and prepped for injections. Topical numbing medication may be applied at this time.

Outline Injection Sites

Using a specialized marker, the planned injection sites are precisely outlined on the lip area.

Select Needle and Prepare Syringe

Based on the treatment plan, an appropriately sized needle is attached to the syringe containing the chosen filler.

Insert Needle and Inject Filler

With a steady hand, the needle is inserted at the outlined injection site, and filler is administered gradually as the needle is withdrawn.

Massage Treatment Area

After injecting into each planned point, Dr. Soni gently massages the lips to evenly distribute the filler.

Assess and Repeat

Dr. Soni carefully examines the lips from all angles, has the patient provide feedback, and repeats steps as needed to achieve optimal aesthetic results.

As Dr. Soni notes, “The injection process is truly an art. My goal is always subtle lip enhancement that looks and feels completely natural for the patient.”

Optimal Injection Sites for Lip Fillers

Understanding the unique anatomy of each patient’s lips is crucial for achieving optimal results with lip fillers.

Dr. Hardik Soni of Ethos Aesthetics + Wellness emphasizes the importance of customizing the injection sites to each individual’s lip structure and facial proportions.

The key areas for lip filler injections include:

  • Vermilion Border: This is the line where the colored part of the lips meets the skin. Enhancing this area helps to gently pillow the lips outward, creating a natural, voluminous look.
  • Cupid’s Bow: The defining curved area of the upper lip is crucial for adding definition and shape. Precise injections here can significantly enhance the lip’s overall appearance.
  • Philtrum Columns: These vertical peaks of the upper lip, when injected, add volume and prevent distortion, contributing to a balanced upper lip.
  • Corners of the Mouth: Small amounts of filler in the oral commissures can lift the corners of the mouth, subtly rejuvenating the overall expression.
  • Lower Lip: Targeting the lower lip and its vermilion border with subtle injections provides support and a natural contour, avoiding an overdone ‘duck lip’ appearance.

Dr. Soni’s specialized techniques focus on these key injection points to ensure symmetrical, balanced, and aesthetically pleasing results.

He states, “Every patient’s lip shape is unique. My approach is to enhance the natural beauty of the lips, ensuring the enhancements complement the individual’s features.”

This tailored method ensures that each lip filler treatment is as unique as the individual, respecting the natural contours and personal aesthetic goals of each patient.

Lip Filler Needle Placement: Best Practices

Proper needle placement ensures correct filler delivery for safe, effective lip enhancement. Dr. Soni’s techniques include:

  • Inserting the Needle Subdermally: The needle should be inserted just under the skin, not too shallow or deep for proper placement.
  • Angling the Syringe Correctly: The syringe should enter at an angle parallel to the lip line. Avoid inserting it straight into the lips.
  • Advancing the Needle Gradually: Injecting slowly and precisely into target areas allows Dr. Soni to expertly sculpt the filler into place.
  • Depositing Small Amounts of Filler: Tiny amounts of product are released as the needle moves to create an even, smooth distribution.
  • Withdrawing the Needle in Controlled Motions: As the filler is injected, the needle is withdrawn at the ideal angle and speed to deposit the product correctly within the lip tissues.

“My specialized techniques allow me to inject filler slowly and precisely for incredibly natural-looking lip enhancement,” shares Dr. Soni. “The needle angle and insertion points are carefully planned to sculpt beautiful results.”

How to Determine the Right Amount of Lip Filler

The amount of filler needed depends on the patient’s facial proportions and desired outcome. Dr. Soni assesses the lips and overall facial aesthetics to recommend the appropriate volume.

Here are some of his determining factors:

  1. Initial Lip Volume: The starting volume of a patient’s lips significantly influences the required amount of filler. Patients with thinner lips might need more filler compared to those with naturally fuller lips.
  2. Lip Shape and Structure: The natural shape and structure of the patient’s lips are crucial in determining the right amount of filler to ensure balance and symmetry.
  3. Facial Balance and Harmony: The evaluation isn’t limited to the lips alone; the filler amount must complement the overall facial features and proportions.
  4. History of Previous Treatments: For patients who have had lip fillers before, the outcomes of these treatments help in judging the optimal filler volume for subsequent sessions.
  5. Desired Outcome: The patient’s aesthetic goals play a pivotal role. For subtle enhancements, a smaller volume like 0.5ml may suffice, whereas more pronounced augmentation might require 1ml or more.

Typical Amount of Filler Used in Lip Filler Treatments

The amount of lip filler administered varies depending on an individual’s existing lip volume and their desired results. However, there are general guidelines to consider:

  • For first-time recipients or those seeking subtle changes, 0.5ml to 1ml of lip filler is commonly chosen. This amount often yields excellent results.
  • In most cases, 1ml is considered a full syringe of lip filler. However, this quantity may not be suitable for everyone.
  • Using more than 2ml of filler can lead to a more dramatic effect, though such a quantity is less common.

Is Overfilling the Lips with Filler Safe?

Overfilling the lips with filler is generally not advisable due to several potential issues:

  • Migration of Filler: Excessive filler can lead to migration beyond the intended area, causing lumps or raised areas around the lips.
  • Bruising and Discomfort: Overfilled lips may experience heightened bruising, discoloration, and discomfort.
  • Permanent Stretching of Skin: Repeated overfilling can act as a tissue expander, leading to permanent skin stretching. When the filler degrades, this may result in sagging and deflated lips, potentially leaving the lips in worse condition than before the treatment.

Addressing Common Concerns and Questions About Lip Fillers

Many patients have questions about lip filler treatments and results. Dr. Soni provides insightful answers to some frequently asked questions:

Do lip injections hurt?

Minor discomfort may occur during the injections, so we use topical anesthetics to ensure maximum comfort.

How long do lip fillers last?

Results typically last 6-12 months, depending on the filler used. Touch-up appointments can help maintain the outcomes.

Can lip injections be dissolved if I don’t like the results?

Injectable hyaluronidase can safely dissolve hyaluronic acid fillers, but for non-HA fillers, a more complex procedure such as surgery would be necessary.

Will lip fillers look fake or unnatural?

When properly done by a professional, lip fillers appear smooth and natural. 

Can I receive lip injections if I have an event soon?

Dr. Soni recommends scheduling lip filler procedures 2-4 weeks before a significant event to ensure ample time for swelling to completely diminish.

Is there anyone who should not get lip fillers?

Those with certain medical conditions or on blood thinners may not be candidates. A consultation visit determines each patient’s candidacy.

Will getting lip fillers stretch out my lips?

Under the expert administration of Dr. Soni, the placement of lip fillers will not result in a permanent alteration of your natural lip structure.
