Who here sees two lines on the side of their nose when they look in the mirror or take a photo? Those are smile lines! If you're younger, these lines might not be very deep. But as you get older, smile lines can get more noticeable, which can affect how our face looks and our confidence.
10 must-know Q&A for people with deep smile lines
How do we fix smile lines? Smile lines are a sign of an aging face, making us look older and less friendly. But there is a clear solution that works well nowadays: smile line fillers.
If you’re interested in this treatment and looking for information, including benefits and important details about smile line fillers to make the face look younger, we’ve gathered the 10 most common questions and answers to help you decide
Q: Why do smile lines become deep? How can we fix them?
A: Deep smile lines happen for many reasons, like natural collagen loss with age, fat loss under the skin, frequent facial movements, and skin that starts to sag as the facial structure changes. This all leads to less skin elasticity.
The best way to reduce deep smile lines is to add fillers. These fillers make the lines look less deep. Also, Ultraformer III can lift sagging cheeks, which can reduce the look of deep smile lines. Ultraformer III also helps prevent lines from getting worse, especially if you start early.
Q: What are smile line fillers? How do they help?
A: Smile line fillers are made from hyaluronic acid, which is injected to reduce deep lines and smooth the skin. When the lines look less deep, the face looks more youthful.
Q: What type of filler is used for nasolabial fold filler injections?
A: The safest filler is hyaluronic acid (HA), approved by health authorities. This filler can hold moisture, making the skin look plump and reducing deep lines.
At good clinics, only approved HA fillers from top global brands are used, and you can check the filler before injection.
Q: Is smile line filler injection painful? How long does it take?
A: The injection is quick and convenient, taking only 20-30 minutes per area. Most fillers contain anesthetic to reduce pain, and numbing cream is also available at no extra cost.
Q: How long do the results of nasolabial fold filler last?
A: Once we understand how nasolabial fold concerns can be treated, the next question is how long the improved appearance—shallower folds and a more youthful look—will last. Generally, the results of Filler program last around 8–12 months, depending on the type of filler used, the injection area, skin condition, post-treatment care, and lifestyle habits. Following the doctor’s recommendations can help maintain the results for as long as possible.
Q: Who is suitable for deep nasolabial fold filler treatments?
A: individuals with deep nasolabial folds caused by loss of fat and collagen beneath the skin or age-related changes in facial structure, such as bone resorption.
Doctors will assess and may recommend fillers alone or with other treatments for best results.

Q: How is Ultraformer III skin tightening for the cheeks related to deep nasolabial folds?
A: Ultraformer III program uses MMFU (Micro and Macro Focused Ultrasound) to stimulate collagen production, lifting sagging skin around the cheeks and reducing smile lines caused by sagging.
Q: Can nasolabial fold filler treatment and Ultraformer III be performed together?
A: Yes, you can do both smile line fillers and Ultraformer III for lifting the cheek area if the doctor assesses your face and recommends it. Doing both can give you the best results—a younger-looking face with smoother smile lines, plumper skin, and tighter cheeks that don’t sag. This combination helps reduce the chance of deeper smile lines in the future.
Q: How should I prepare before getting nasolabial fold filler treatment?
A: There’s actually not much you need to do to prepare for filler treatments. However, if you easily bruise or worry about needle marks, follow the doctor’s tips below to reduce visible marks or bruising, which can sometimes take longer to heal.
Q: What precautions should be taken after nasolabial fold filler treatment?
A: Drink lots of water in the first month to help fillers settle. Avoid pressing on the area, and stay away from high-heat activities like saunas or laser treatments until fillers fully set.
