Why Are Lip Fillers Popular

Lip fillers are popular because they are temporal, long-lasting, and inexpensive. Lip fillers offer immediate results with minimal risks. Lip fillers enhance facial features and trigger collagen production.

A patient can reduce aging signs but cannot stop aging. Fine lines like wrinkles appear on the face while aging. As you advance in age, the signs become more dominant because less collagen is produced. Collagen is a protein found in connective tissues, skin, tendons, and cartilage thatmaintains skin structure and elasticity. Cosmetic procedures enhance the beauty andtreat dermal scars and congenital conditions. Use cosmetic products, plastic surgery, or dermal fillers.Cosmetic products may be ineffective, and plastic surgery is expensive and permanent. This article exploreslip fillers and why they are popular.

What Are Lip Fillers?

Lip fillers are gels used in invasive procedures to plump thin lips, treat scars, and redefine lip lines. Lip fillers are injected into the lips for cosmetic purposes. A patient can use lip fillers to treat inborn scars.

Types of Lip Fillers

Polylactic Acid

According to Christen &Vercesi (2020), polylactic acid dissolves into the body to trigger collagen production. Luque –Agudo et al. (2021) suggested that the effect of polylactic acid is seen after two weeks. Polylactic filler plumps thin lips and redefines lip lines and borders.


According to Karthik & Mohan(2017), polyalkylimide filler does not react with the body, but a collagen layer is formed around it after injection. Polyalkylimide is best used to plump thin lips because a single injection can deliver more polyalkylimide.

Hyaluronic Acid

According to Dovedytis et al. (2020), hyaluronic acid is a gooey, slippery substance found in joints, skin, and eyes; it helps joints move smoothly and hydrate the skin. It can be used to improve facial volume and plump thin lips.

Calcium hydroxylapatite

According to Shirshakova et al. (2020), calcium hydroxylapatite is a mineral-like substance found in human bones and enamel; it helps with bone growth. Calcium hydroxylapatite used in fillers is biosynthetically produced to minimize allergic reactions. Calcium hydroxylapatitetreats scars on lips, plump thin lips, and redefines lip lines.

Polymethyl-Methacrylate Microspheres (PMMA)

PMMA is a more permanent filler than other fillers like collagen replacement therapy. Smaller doses of PMMA are injected for three months until the desired results are achieved. PMMA is used to treat lip scars due to injury or inborn conditions and redefine lip borders.

Lip filler results are immediate. A patient doesn’t wait for months to heal to notice the changes. A patient can resume work after lip fillers if it does not involve heavy lifting and sweating.

Triggers Collagen Production

Collagen is produced to maintain skin structure and elasticity. Fillers like polylactic acid trigger collagen production, which will smooth wrinkles and treat sagging skin, giving a youthful look.

Enhances Facial Features

Due to age, facial features like jawline and cheekbones may become less pronounced because of sagging skin. Medical conditions like cancer may contribute to volume loss. Shin et al. (2019) claimed that Lip filler could enhance facial features by improving the volume and triggering collagen production.

Procedure for Lip Fillers

A cosmetic doctor examines lips and marks areas to be treated. An anesthetic is applied to numb the skin. The process is not painful, but a patient might experience some discomfort. A cosmetic doctor injects the filler under the skin.

Side Effects and Precautions

Lip fillers are generally safe because they are minimally invasive procedures performed by experiencedcosmetic doctors. After the injection, a patient can experience some swelling, pain, or bruising. Infection at the injection point and fractured or blocked blood vessels are some complications a patient can get when lip fillers are done wrong. Always do lip fillers in a clinic setting to avoid such complications.

Cost of Lip Fillers

The cost of lip fillers is determined by; the type of filler, the cosmeticdoctor’s experience,the location, and the number of syringes you will need. Fillers that last longer are pricey when compared to those last for a few months. A more experienced doctor will charge more than other doctors. Lip fillers are also pricy because cosmetic procedures are not included in medical covers.
