acid on the lips how to use

Acid in the Lips: What type of hyaluronic acid is used to volumize the lips?

Full and contoured lips have become a symbol of youth and beauty, and the hyaluronic acid injection procedure is undoubtedly one of the most sought-after aesthetic treatments to achieve this effect.

In this article, we will analyze step by step what this procedure entails, which are the types of hyaluronic acid available on the market, the injection rules to avoid complications, the post-procedure recommendations and the duration of the effects.

If you are thinking of trying this procedure for the first time, read carefully and inform yourself as much as possible before taking the decisive step!


The first injection of hyaluronic acid in the lips. What to expect?

Initial consultation

Before any aesthetic procedure, it is essential to start with a detailed consultation with a certified specialist. During the appointment, the doctor will evaluate the anatomy of your lips, discuss your expectations and determine which technique and type of hyaluronic acid are best suited to achieve the desired result.

This discussion is also an opportunity to clarify any fears and ensure that mutual trust is at work.

Anesthesia and preparation of the area

To reduce any discomfort, a local anesthetic gel or numbing cream is usually applied to the lip area before the injection. This step ensures that the procedure goes as smoothly as possible. The injection area is then thoroughly cleaned to prevent any risk of infection.

The actual procedure

The injection is quick – usually between 15 and 30 minutes – and is done with either very fine needles or microcannulas. The choice of technique depends on the preferences of the specialist and the structure of your lips. Using microcannulas can reduce the risk of bruising and edema because they allow for even distribution of the acid.

Immediate sensations and results

During the injection, you may feel a slight pressure or a sensation similar to a small prick. These sensations are usually well tolerated and pass quickly. The volumizing effect is visible immediately, but the final result will stabilize in a few days as the post-injection edema subsides.


Types of hyaluronic acid by molecule and which are the most popular brands for lip plumping

Hyaluronic acid is a natural substance, but synthetic and modified versions are used in aesthetic procedures to achieve increased durability and an optimal filling effect. Choosing the right type is based on two main factors: the size of the molecules and the degree of cross-linking.

The size of the molecules

  • Large molecules: They give a firmer texture, ideal for contouring and defining lips. It is mainly used when a well-defined shape is desired.
  • Small molecules: They integrate more evenly into the tissue, providing a more subtle plumping effect and deep hydration. They are often chosen to correct minor imperfections and provide a natural feel.

The degree of crosslinking

Cross-linking refers to the process by which hyaluronic acid molecules are "chained" together to form a more stable network. A higher degree of cross-linking gives the product increased resistance to degradation, which means that the effect will last longer.

However, too much cross-linking can produce an overly rigid or artificial appearance. Therefore, specialists are always looking for the ideal balance between durability and naturalness.

Popular lip plumping brands

  • Juvederm: One of the most well-known brands in the field, with products such as Juvederm Ultra and Juvederm Volbella, which are appreciated for their fine consistency and harmonious integration into the lip tissues.
  • Restylane: Restylane Silk is often recommended for lips due to its delicate texture and natural effect, offering a balanced and long-lasting result.
  • Belotero: This brand stands out for its subtle and natural results, making it a great option for those who want a discreet but effective volumization.

Each type of hyaluronic acid has its own characteristics, and the choice is made according to your expectations and the recommendations of the specialist. A detailed discussion during the consultation will clarify which option is right for you, thus ensuring a final result that corresponds to your wishes and anatomical particularities.


Rules for injecting hyaluronic acid into the lips

To achieve optimal results and to avoid post-procedure complications, it is important that the injections are performed carefully and according to strict rules:

The choice of the specialist

The most important rule is to choose a doctor or esthetician with experience and positive reviews. An experienced professional knows the anatomy of the lips and the correct injection techniques, which significantly reduces the risk of complications.

Injection technique

  • Use of microcannulas: This is often preferred because it allows for an even distribution of hyaluronic acid and reduces the risk of perforating blood vessels, thus lessening the possibility of bruising.
  • Correct dosage: The amount of acid administered must be adapted to each individual patient. An excess of product can lead to excessive puffiness and an unnatural appearance.
  • Injection points: The doctor will mark the area to ensure that the hyaluronic acid is distributed evenly, avoiding excessive concentration in one place, which could lead to the formation of nodules or asymmetries.

Hygiene and sterilization

Before injection, the treated area must be thoroughly cleaned with antiseptic solutions, and the instruments used must be completely sterile. These measures are essential to prevent infections and other complications.

Post-injection massage

After the injection, the doctor may perform a gentle massage of the lips to ensure an even distribution of the acid. However, the pressure applied must be very moderate, so as not to alter the result.

Immediate monitoring

At the end of the procedure, the specialist will monitor the evolution of the lips to detect possible signs of edema or other adverse reactions. In case of intense discomfort or unusual symptoms, the patient should contact the doctor immediately.

Compliance with these rules significantly contributes to achieving a successful result, with natural and harmonious lips, without unwanted complications. The process may seem technical and detailed, but every step is thought out to ensure patient safety and satisfaction.

What am I not allowed to do after the injection of hyaluronic acid in the lips?

The post-procedure is just as important as the injection itself. Adherence to certain recommendations can make the difference between an optimal result and the occurrence of temporary or, rarely, serious complications.

1. Avoid exposure to intense heat

For at least 24-48 hours after the procedure, it is recommended to avoid:

  • Saunas and hot baths
  • Prolonged exposure to the sun or the intense light of tanning lamps
    They can worsen edema and affect the even distribution of hyaluronic acid.

2. Give up drinking alcohol

Alcohol dilates blood vessels, which can increase the risk of bruising and swelling. For at least 48 hours after the procedure, it is advisable to avoid drinking alcohol, to allow a peaceful healing of the treated area.

3. No excessive massaging or lip manipulation

After the injection, the area should be left undisturbed. Avoid:

  • Excessive massaging or rubbing of the lips
  • Applying high pressure that could redistribute the acid unevenly
    The doctor will give you specific instructions, and following them is essential for an optimal aesthetic result.

4. Avoid vigorous exercise

Vigorous physical activities, which increase blood circulation, can intensify the edema in the first 24-48 hours. It is recommended to opt for light activities and let your body adjust to the treatment.

5. Do not use makeup on the treated area

In the first few hours after the procedure, it is advisable to avoid applying make-up on the lips, in order not to irritate the skin and not to compromise the hygiene of the area. Wait until your doctor confirms it is safe to apply cosmetics.

6. Avoid aggressive facial treatments

For a few days after the injection, give up:

  • Laser treatment
  • Chemical peels or other aggressive facial procedures
    They can interfere with the healing process and affect the final result.

Following these post-procedure recommendations will not only ensure a quick healing, but will also help maintain a natural and harmonious appearance of the lips. Every patient is different, so it's important to follow the specific advice you receive from your specialist.


How long does hyaluronic acid last in the lips?

The duration of the effect of the hyaluronic acid injection varies depending on several factors, including:

  • The type of product used
  • Injection technique
  • Individual metabolism
  • Environmental factors and lifestyle

Average duration of effect

In general, results can last between 6 and 12 months. Brands with a higher degree of crosslinking, such as Juvederm Volbella or Restylane Silk, are designed to provide prolonged results, but each body has its own rate of metabolism of hyaluronic acid.

Factors influencing duration

  • Product type: Products with a high degree of crosslinking are more resistant to degradation and therefore can maintain the volumizing effect for a longer period.
  • Treated area: Lips, being an area with intense blood circulation, can metabolize the acid faster than other areas of the face.
  • Lifestyle: Sun exposure, diet, smoking and other environmental factors can influence the duration of the effect. A proper care routine can help maintain the results for a longer period.

The importance of retouching

To maintain the full and contoured appearance of the lips, many specialists recommend periodic touch-ups. The discussion with the doctor will help you establish a maintenance plan adapted to your needs, so that you can benefit from the desired result for as long as possible.


Hyaluronic acid injection for lip volumization is an effective, minimally invasive procedure with immediate results that has conquered millions of people around the world. From the initial consultation to the strict observance of the post-procedure rules, each stage is designed to ensure a natural and harmonious result.

Choosing the right type of hyaluronic acid – whether you opt for products from Juvederm, Restylane or Belotero – should be made based on a careful assessment of your needs and the recommendations of a trusted specialist. The injection technique, applied with care and respect for the anatomy of the lips, contributes to minimizing complications and achieving an optimal aesthetic effect.

Do not forget that the final results will be seen after a few days, as the post-procedure edema will reduce and the volumizing effect will be established. The duration of the effect, usually between 6 and 12 months, can be extended by periodic touch-ups and by maintaining a healthy lifestyle.

Finally, the key to success in this procedure is information, choosing an experienced specialist and strictly following the recommendations before and after the injection. Thus, your lips will not only be voluminous, but will radiate a natural charm that will make you feel really confident.
