What is Lip Filler?
Lip filler is a non-surgical aesthetic procedure that consists of applying a dermal filler, usually based on hyaluronic acid, to the lips to increase volume, define the contour and improve hydration.
Benefits of Lip Filler
- Increased volume: lips become fuller and fuller, providing a more youthful appearance.
- Contour definition: The lip contour is more defined, enhancing natural beauty.
- Hydration: Hyaluronic acid has moisturizing properties, leaving lips softer and healthier-looking.
- Improved self-esteem: A beautiful smile and well-defined lips can increase self-esteem and confidence.
- Natural results: when performed by a qualified professional, the result is natural and harmonious with the other features of the face.

1 – Enhances Facial Harmony
Lips play a crucial role in facial aesthetics. Lip fillers can correct asymmetries, add volume, and define contours, creating a more balanced appearance.
The procedure can be customized to suit individual preferences, whether aiming for fuller lips or simply restoring lost definition and plumpness over time.
2 – Natural and Personalized Results
Thanks to advanced techniques and the use of hyaluronic acid—a safe, biocompatible substance—lip fillers provide natural-looking results.
A qualified professional evaluates each patient’s facial proportions to ensure the outcome is harmonious and proportional.
3 – Boosts Self-Confidence
Many patients report a significant boost in self-esteem after getting lip fillers. Feeling good about one’s appearance can have a positive impact on both personal and professional life.
As Camila, 32, shared: “I always had thin lips and felt insecure. After the procedure, I feel more confident and comfortable smiling and wearing makeup.”
4 – Quick and Minimally Invasive Procedure
One major advantage of lip fillers is their convenience. The procedure typically takes 30 to 40 minutes and doesn’t require hospitalization.
Recovery is also quick, with mild swelling during the first few days, allowing most people to resume their regular activities almost immediately.

Ingredients for lip fillers
To achieve safe and satisfactory results, it is essential to understand the ingredients used in lip fillers.
- Hyaluronic acid
- Calcium Hydroxyapatite
- Autologous Fat
- Polymethylmethacrylate (PMMA)
Find out more about each one below:
1 – Hyaluronic acid
Hyaluronic acid is the most common ingredient in lip fillers and, for good reason, is considered safe and highly effective.
What is it? Hyaluronic acid is a substance naturally found in the human body, especially in the skin, joints and connective tissues. It has the ability to retain large amounts of water, which contributes to the hydration and elasticity of the skin.
The benefits are:
- Natural volume: Allows you to adjust the amount injected to create personalized results.
- Prolonged hydration: Attracts water to the lips, leaving them looking healthy and lush.
- Reversibility: If the patient wishes to reverse the filler, an enzyme called hyaluronidase can be applied to dissolve the product.
Popular brands that use hyaluronic acid include Juvederm, Restylane and Belotero.
2 – Calcium Hydroxyapatite
Calcium hydroxyapatite is another ingredient used in fillers, although it is more common in areas of the face that don’t require as much mobility.
How does it work? This compound stimulates collagen production in the area where it is applied. On the lips, it can be combined with hyaluronic acid for longer-lasting results.
The main advantages are:
- Longer lasting compared to hyaluronic acid alone.
- Helps improve the texture and firmness of the skin around the lips.

3 – Autologous Fat
The use of autologous fat, i.e. fat taken from the patient’s own body, is an alternative for those looking for a more natural and permanent method.
How is it done? The fat is collected through liposuction in areas such as the abdomen or thighs, purified and then injected into the lips.
Benefits:
- Avoids the use of synthetic substances.
- The results are permanent, although some of the fat may be reabsorbed by the body over time.
Disadvantages:
- More invasive procedure.
- Longer recovery time compared to hyaluronic acid fillers.
4 – Polymethymethacrylate (PMMA)
PMMA is an ingredient used in permanent fillers. It consists of microspheres that are suspended in a gel.
Advantages:
- Permanent results, eliminating the need for frequent reapplications.
- Suitable for patients who want longer-lasting structural changes.
Care:
As it is a permanent material, PMMA requires extreme caution and should only be applied by experienced professionals. It can be difficult to remove if you are dissatisfied with the result.
What is the best ingredient for lip fillers?
Choosing the best ingredient depends on your aesthetic goals, personal preferences and the recommendations of the professional in charge of the procedure. Hyaluronic acid is the most popular option, due to its safety, naturalness and reversibility.
Data on lip fillers
According to the Brazilian Society of Dermatology (SBD), lip fillers are among the most popular aesthetic procedures in recent years.
A study by the American Society of Plastic Surgeons found that 92% of patients who underwent lip fillers reported being very satisfied with the results.
Influencers and celebrities, such as Kylie Jenner, have popularized lip fillers, inspiring many people to consider the procedure.

Lip Filler Risks
Like any aesthetic procedure, lip fillers have some risks, such as:
- Swelling and swelling: these are common reactions and usually disappear within a few days.
- Hematoma: May occur in some cases, but is generally absorbed by the body.
- Infection: It is rare, but can occur if hygiene standards are not followed.
- Unsatisfactory results: choosing the professional and type of filling are essential to avoid unwanted results.
- Product migration: In rare cases, filler may migrate to other areas of the face.
Post-Procedure Care
To ensure an overwhelming result and avoid complications, it is important to follow the professional’s instructions after the procedure, such as:
Avoid sun exposure: Sun exposure can increase the risk of occurrence and exposure. Do not massage the area: Massage may cause product migration.
Avoid hot foods, drinks and liquids: they can increase swelling.
Use sunscreen: Protects lips from solar radiation.

How to Choose a Good Professional
