How Long Do Lips Swell After Fillers

Swelling is one of the side effects of lip filler treatments. However, the swelling fades away after some time. This article highlights what fillers are, including reasons patients go for lip filler treatments, their side effects, and how long lip swelling lasts.

Lip fillers are substances injected beneath the lips’ tissues to enhance appearance, eliminate wrinkles, and restore lip size by making the lips hydrated, plump, and smooth. Cosmetic doctors or aesthetic practitioners do lip filler procedures. They numb the lips before they perform the filling procedure. During the filling procedure, the patient can experience some discomfort. After lip filler treatment, patients can experience swelling. However, the swelling does not last long.

What are Lip Fillers?

Lip fillers are injectable gel-like substances injected into the skin tissues to make them plump and voluptuous. Ashok &Gnanashanmugam (2020) suggested that patients use lip fillers for various reasons, such as to enhancetheir appearance and restore lip size. The lips may lose volume for several reasons, including aging and smoking. Saggy and loose skin are caused by decreasedcollagen and elastin levels.

Signorini et al. (2016) explained that most fillers contain hyaluronic acid, and lip fillers are no exception. Hyaluronic acid is present in the body and can be used as a supplement to add volume to the lips. Funt& Pavicic (2013) showed that lip fillers are not permanent, and their results may last for 12 to 18 months, depending on various factors, such as an individual’s metabolic rate. Other supplements or injections are needed to maintain full, plump, and smooth lips.

Reasons for LipFillers

The lips may lose volume due to various factors such as genetics, excess exposure to UV rays, aging, and smoking. Czumbel et al. (2021) stated that patients might opt for lip fillers to restore the lips to their size.

Smoothening of Wrinkles

According to Amaro-Ortiz, Yan &D’Orazio (2014), the formation of wrinkles is caused by several factors, such as aging, excessive exposure to UV rays, and fat loss. When one laughs or smiles, wrinkles may form on the sides of the mouth. By increasing the volume of the lips, you may curb the formation of wrinkles on the sides of the mouth.

The cosmetic doctor can inject lip fillers to enhance the appearance and general facial outlook.Chirico et al. (2021) suggested that fillers are injected under the skin tissues to increase lip volume and make lips plump and hydrated. Plump lips can improve one’s appearance. Therefore, lip fillers can be used to boost the patient’s appearance. The study above suggested that patients who have asymmetrical lips can also opt for lip fillers.

Wollina et al. (2020) revealed that lip filler treatments might have side effects, including;

  • Bruising
  • Swelling

  • Blindness
  • Asymmetrical lips

Patients are advised to seek lip treatments from qualified cosmetic doctors to avoid complications. Cosmetic doctors do not require a license to practice their aesthetic services in the UK. Therefore, there are a lot of quack aesthetic practitioners. Quack aesthetic practitioners can inject the blood vessels or tissues,leading to complications.

How are Lip Fillers Done?

Before undergoing a lip filler procedure, ensure you consult a cosmetic doctor or aesthetic practitioner to ascertain the safety of the products. A cosmetic doctor will analyze your lips and test if the patient has allergies.

Anaesthetic practitioner will inject minute amounts of lip filler into the lips. Before the lip fillers are injected, the cosmetic doctor applies a numbing cream or nerve block to the lips. This will prevent any pain during the process.

The lip-filling procedure takes a short time and has no downtime. Therefore, one can go back to their day-to-day activities after lip fillers. Patients can experience bleeding, swelling, bruising, and redness after the filler treatments. However, these side effects are short-lived and fade within a few days.

What to Avoid Before Lip Filler Treatments

Patients should avoid alcohol before lip treatments. Alcohol is a vasodilator and can dilate the bloodvessels, increasing the blood flow. This can hinder the lip treatment and can also lead to bleeding during the treatment.Blood-thinner medications should also be avoided.
