Lip fillers: all you want to know

Posted at:

Lip fillers with hyaluronic acid have become a growing trend in the world of facial cosmetics.

With celebrities and influencers embracing this procedure, many people have been looking for information about what this treatment involves, how long it lasts, whether it hurts, how it works, who it is suitable for and whether it is safe. In this article, we will address all your questions about lip fillers with hyaluronic acid.


Lip filler: what it is and what it’s used for

Lip filling with hyaluronic acid is a cosmetic procedure that aims to improve the volume and shape of the lips. It is a very interesting solution for those who have thin lips or have lost lip volume with age. Lip fillers also help to improve the lip contour of those who have lost contour definition over time (very common in older people).


What is hyaluronic acid?

Hyaluronic acid is a natural substance found in the human body, which is responsible for keeping the skin hydrated and plump. As we age, the production of hyaluronic acid decreases, leading to a loss of skin volume and elasticity. Hyaluronic acid used in lip fillers will help regain volume and firmness in a natural and safe way.

Filling with hyaluronic acid is also used to fill wrinkles (nasogenian groove, perioral wrinkles, etc.), increase buttock volume, rhinomodelling procedures to adjust the shape and contour of the nose, increase volume and projection of the chin, among others.


Does lip filling hurt?

Generally, the lip filler procedure is well tolerated, as the product itself usually contains anaesthetic in its composition. In addition, it is possible to apply local anaesthesia before treatment to bring more comfort to the patient.


How is lip filling done?

The process begins with a consultation with the Living Clinic dermatologist, who will be responsible for the lip filling, where she will discuss your specific goals and answer all your questions about the filler.

The physician will assess the structure of your lips and skin quality and, taking into account your goals, will decide the amount of hyaluronic acid needed to achieve the desired results.

Before starting the procedure, if the patient so wishes, local anaesthesia will be applied to the lip area.

Hyaluronic acid is then injected into the lips with a small cannula or needle, depending on the case. The injection is done with precision to shape and sculpt the lips according to the patient’s preferences.

The procedure is quick and the results are immediately visible, although some swelling and redness after the treatment is normal.


How long does the filler last?

Lip fillers with hyaluronic acid usually last 6 to 12 months. This duration varies from person to person and is also influenced by the choice of product used. At Living Clinic only premium brands are used, which provide safety and greater durability in results. The body will eventually absorb the hyaluronic acid, requiring touch-up treatments if you want to maintain the results for longer.


How many sessions are needed?

The number of sessions needed depends on individual goals and lip volume. Most people achieve their desired result in a single session. However, in certain cases, an additional session may be necessary.


When do the filling results appear?

The results of lip fillers with hyaluronic acid are visible immediately after the procedure. However, it is normal for there to be a slight initial swelling that will decrease in the hours (or few days) following the treatment.


What is the recovery period?

Recovery from lip fillers is generally quick. There may be swelling and some tenderness for the first 24-48 hours. However, most people can resume normal activities shortly after treatment.


Post treatment care

After lip fillers, it is important to avoid touching your lips and applying makeup for the first few hours. It is also recommended to avoid exposure to the sun, swimming pools, hot baths and intense exercise in the first 24 hours.

As previously mentioned, swelling in the lips usually subsides within the first 24-48 hours.


What are adequate lip filling proportions?

The ideal proportion of lip filler varies from person to person and depends on their aesthetic goals. However, our dermatologist is the ideal person to advise and guide you through this process. The objective will always be to obtain results that are as natural and proportional as possible.


What is the “gloss effect”?

The “gloss effect” refers to the shine and voluminous, hydrated appearance that lip fillers with hyaluronic acid can provide to the lips. It’s one of the reasons this procedure is so popular.


Can lip fillers be applied on herpes ?

It is possible to perform lip fillers on people with a history of herpes in the lip area. However, in some cases certain measures are advised to prevent herpes recurrences, which is why medical consultation prior to the procedure is so important.


Lip filler risks

Lip fillers with hyaluronic acid are generally safe, but like any medical procedure, they may involve some risks, including bruising or adverse reactions.

The greatest risk with any filler is that of intravascular injection with consequent necrosis. However, the physician who works in this area has extensive knowledge of anatomy and the precautions to be taken when carrying out this type of procedure. The serious cases that we sometimes become aware of through social media tend to occur when untrained individuals inject poor quality hyaluronic acid or unregulated substances, large volumes of product and, of course, due to a lack of technique and anatomical knowledge.


From what age can I get a lip filler?

The treatment is recommended for adults, ideally with thin lips (constitutional or due to loss of volume due to natural aging).


Which professional does the lip filling?

Lip fillers are performed by the Living Clinic dermatologist.
