It is important to note that lip fillers are not permanent. They can last approximately between 6 to 12 months and then wear off. After this period, the procedure is repeated. It is greatly affected by the type of filler used. Most fillers are made of hyaluronic acid, which becomes an integral part of the skin tissue after injection. Hyaluronic acid is a bacteria substance that attaches itself to water molecules in the skin to increase the volume of the lips. There are different brand names of hyaluronic acid in the market, each taking extra time to wear off. According to Cheng et al. (2016), lip filler will slowly degrade a few months after injection. Still, the effect will not be visible at this time because filler can dissolve in water. One will notice a decrease in the volume of lips towards the midpoint of the filler longevity. It is explained that doing a filler addition at this point can help improve the effectiveness of the filler and sustain it longer.

Details of Lip Filler Procedure

Before the Procedure

The first step is to schedule an appointment with a cosmetic doctor. During the appointment day, the patient will explain to the doctor how they want the lips to look. The cosmetic doctor will note the current appearance of the lips. At this stage, the doctor’s main aim is to get relevant health information about the patient, like any preexisting health complications like allergies or whether the patient has any prescribed medication.

During the Procedure

To numb the lips, the cosmetic doctor will apply a topical anaesthetic on your lips. Then some injections may be injected inside the mouth to numb the top and bottom parts of the lips, and numbing take 15-30min. When the lips are completely cool, the cosmetic doctor injects the filler into the lips. This process may take 30min to 1 hour. The cosmetic doctor may apply an anti-inflammatory ointment on the lips after the procedure to minimize bruising and swelling.

Afterthe Procedure

The cosmetic doctor may take a few minutes to massage the lips to absorb the filler. At the same time, they will monitor the patient to see any possible side effects. One may note some red spots on the areas where the needle was inserted. Lips may feel different because of the presence of the filler. Some patients may swell after the procedure, but it may take 24-48 hours for the swelling to go away. Bruising may also occur and may take a week to disappear.

The cosmetic doctor may give some tips after the procedure as follows:

  • Patients should drink a lot of water

  • Patients should avoid touching their lips after the injection procedure.

Advantages of Lip Fillers

  • The risk of getting complications after a lip filler procedure is minimal.
  • Abduljabbar & Basendwh (2016) stated that lip fillers are reversible. If a patient is not pleased with the outcome of the injection, the cosmetic doctor can inject hyaluronidase enzyme into the lips to dissolve the filler.
  • Even though fillers do not have a permanent effect, hyaluronic acid can be injected gradually to achieve the desired outcome.
  • Customization. The filler injection can be based on the patient’s needs. You can decide to add volume only on one lip.
