Life is full of reasons to smile, but from an aesthetic standpoint, smiling can create lines around your mouth. Smile lines, also known as laugh lines, are deep lines on both sides of the lower half of your face that start from your mouth.
These lines are caused by the heavy movement of the muscles that are activated when you smile. They are more noticeable in older people and in people who are thin and do not have much fat in their face. Although some people see these lines as a sign of a happy life, others feel that smile lines make them look older than they are.
Treating smile lines with smile line fillers
The repeated movement of the facial muscles when smiling causes the skin to loosen and permanent wrinkles to form around the mouth. Smiling also wears down the tissue of that area of the face and creates lines that remain even after the smile has ended.
As part of the aging process, the skin loses its fat and elasticity, and the appearance of smile lines gradually deepens. Fortunately, it is possible to reduce the appearance of these unwanted folds. Dermal filler injection can make the appearance of smile lines fainter by filling the skin from within.
The goal of this treatment is to smooth smile lines so that you look fresher.
How do dermal fillers work?
Dermal fillers are an injectable treatment often used to help increase facial volume, correct facial lines and minimize wrinkles.
There are two types of wrinkles on the face:
1. Static wrinkles: lines or folds on the face that are present and visible when a person's face is at rest and still.
2. Dynamic wrinkles: wrinkles caused by repeated muscle contractions, such as smiling or squinting around the eyes, which disappear when the face is smoothed out.
By adding volume under the skin, dermal fillers are most effective at eliminating static wrinkles.
Filler longevity versus the longevity of results
One of the most common questions doctors are frequently asked is "How long do fillers last?" To understand the answer to this question, we need to consider the physical and chemical properties of the products. What patients really want to know is how long their results last after filler injection. This distinction is important.
Factors that affect how long a filler lasts after injection include:
- The filler material
- The consistency of the filler
- The treatment area
- How quickly the filler is metabolized in your body
In fact, even after the injected filler has been absorbed by the body, you can still enjoy visible facial rejuvenation or contouring results. This is because filler injection can stimulate collagen production in the treated area. This means that your body produces a substance that restores the volume of that area.
What factors affect how long a filler lasts?
In addition to the type of filler product used, several other factors can also affect the longevity of a dermal filler. These include:
- The place on your face where the filler is used
- The amount injected
- The rate at which your body metabolizes the filler
In the first few months after injection, fillers slowly begin to break down. But the visible results remain stable because fillers have the ability to absorb water. However, around the middle of the filler's expected lifespan, you will notice a decrease in volume.

Do fillers go away?
If you are planning a dermal filler treatment, you may ask yourself, "How long do fillers last in your face?" Does a filler ever go away? Facial dermal fillers are usually not permanent, so you should plan to have another injection every 3 to 12 months, depending on the type of filler you receive and the area of the face where the filler is injected.
How long do smile line filler results last?
The longevity of results can vary from person to person. For most clients, smile line fillers last 6 to 12 months before the treatment needs to be repeated. Dermal fillers are not permanent, and the body absorbs the filler over time. During the consultation session, your doctor will recommend a treatment plan; in fact, they will choose the right filler for you and advise you on when to come back for your next treatment.
As mentioned, most smile line fillers will last 6 to 12 months. But there are important points to consider, such as:
- The consistency of the filler used
- Your age
- The depth of the lines
For most smile line injections, it is recommended to use medium fillers. Medium fillers are used for wrinkles that are not very deep. You can expect the results of these fillers to last about 6 to 12 months. If you have very deep smile lines, the results may not last long unless your technician uses a firmer-consistency filler.

Final note
It is important to remember that as we age, our face loses volume, so to maintain optimal results and a fresh appearance we need to use facial skin volumizing techniques. Dermal filler injection is one of these ways. But since the lifespan of these fillers is not permanent and they are absorbed by the body after a while, re-injection must be done after some time has passed.
