How Long Do Smile Line Fillers Last?

Smiles and laughter are integral to getting through life, so it makes sense that most people would want to maintain their natural teeth as long as possible. However, this desire to keep teeth longer than necessary can result in a smile line that won’t go away even with filler. This article explains how long the smile line fillers last.

Individuals with little to no hint of a smile line might not be aware that fillers can last longer than they think. Fillers are one of the best options for getting rid of this unsightly imperfection and giving ourselves that much-needed lift. However, a common question is how long will smile line fillers last.

It Depends onthe Product

Smile line fillers are cosmetic fillers used to smooth out fine lines and wrinkles on the face. They are used in a procedure called smile lift, which uses radio frequency energy to stimulate collagen growth in the skin.Smile line fillers do not last as long as lip fillers or wrinkle fillers, which can last up to a year with proper care and maintenance. Smile line fillers typically last 6 to 12 months, depending on the product and if they cause any damage during the procedure.Stimulating collagen growth may increase the longevity of your smile line filler, but this will be based on individual results. Make sure you use a high-quality brand of smile line filler. This will ensure that the smile lines stay in place longer than if one used a lower-quality product. One should ensure they are using enough of the product to cover all smile line gaps. If there are still gaps between theteeth, they may not have used enough products or a low-quality brand that does not last as long as high-quality brands.

It Varies from Person to Person

Smile lines are very subtle and can be repaired by a simple injection of hyaluronic acid. However, an individual must choose a good cosmetic doctor who is experienced in this area. The best way to know if the cosmetic doctor is experienced is to ask for references from previous patients. If they have no referrals, it may be best to find another cosmetic doctor.Some people may experience significant swelling after getting a smile line filler procedure; others may have very little. To help prevent swelling, one should follow these instructions:

  • Drink plenty of water
  • Take mild pain medication

The filler’s longevity depends on how well one takes care of it. The more time onespends doing home maintenance — such as brushing their teeth or eating fruits and vegetables — the longer it will stay in place.The treatment lasts for about six months before it needs to be redone. It’s best to get a follow-up treatment every six months for maximum results.

Factors that Affect the Duration of Dermal Filler


The older you get, the more likely the body will produce excess collagen and other biological materials.(Horn & Trafford, 2016) This could diminish the effectiveness of dermal fillers.


The body of an obese individual will produce more collagen and other biological materials that can decrease the effectiveness of dermal fillers. Hemodialysis (permanent kidney dialysis) can cause blood vessels to become more permeable, leading to more inflammation and inflammation-related complications, such as tissue damage around the injection site.


Li et al. (2017) found that smoking cigarettes increase blood pressure and heart rate, which may increase the risk of complications from dermal fillers.


Certain medications can also affect how well dermal fillers work in the body. For example, Liu et al. (2013) noted that corticosteroids like hydrocortisone might weaken the skin’s natural defenses against infection by making it more susceptible to cellulitis.

Which Fillers are Used for Smile Lines?

The most popular fillers for smile lines contain silicone gel that can be injected into the cheeks and upper lips to add volume to these areas. It is a great option for those with thin or weak lips, but it can also be used in other areas of the face, such as between eyebrows or around the eyes. Also, a hyaluronic acid filler that can be injected into the nasal skin to create a youthful look and feel can be used. This product is great for adding volume where wrinkles tend to form due to aging and sun exposure.Hyaluronic acid dermal fillers can be used independently, but they are often combined with other fillersfor optimal results.
