Nasolabial Folds Treatment in Singapore
Nasolabial folds, commonly known as laugh lines or smile lines, are the creases that extend from the sides of the nose towards the corners of the mouth. Everyone naturally has some degree of nasolabial folding, especially when smiling, but these folds can become deeper and remain more visible at rest as the face ages.
Unlike fine wrinkles that develop mainly within the skin, nasolabial folds involve several facial structures. Changes in skin elasticity, collagen, facial volume and structural support can all make the folds appear deeper over time.
What Causes Nasolabial Folds?
Nasolabial folds form where the cheek meets the area around the mouth. Facial movement naturally creates a crease in this region when you smile or make certain expressions. As we age, several changes can make this crease more prominent:
- Changes in midface volume and facial support
- Reduced collagen and elastin within the skin
- Increasing skin laxity
- Changes in facial fat compartments with age
- Repeated facial movement
- Sun exposure and photoageing
- Genetics and individual facial anatomy
- Lifestyle factors such as smoking
Ageing can also change the position and support of the cheek tissues above the nasolabial fold. As these structural changes develop, the fold may become deeper and more noticeable even when the face is relaxed. Dry or dehydrated skin can make fine surface lines look more noticeable, but dehydration itself does not cause the deeper structural nasolabial fold.
Why Do Nasolabial Folds Become Deeper With Age?
A nasolabial fold does not develop from one single ageing process. With age, the skin gradually produces less collagen and elastin, which reduces its firmness and elasticity. At the same time, changes in facial fat, bone and other supporting structures can alter the way the midface supports the cheek.
These changes can increase the contrast between the cheek and the nasolabial fold, making the crease appear deeper. This is why treating nasolabial folds requires more than simply looking at the line itself. A doctor should assess the cheeks, midface support, skin laxity and the fold itself before deciding where treatment may be most appropriate.
How Are Nasolabial Folds Treated?
Treatment depends on what is making the nasolabial fold prominent. For some people, volume and structural changes contribute most to the fold. For others, skin laxity and changes in skin quality play a larger role. Many people have a combination of these factors.
Treatment may therefore involve dermal fillers, skin tightening or energy-based treatments, depending on the individual's facial anatomy and degree of ageing.
Dermal Fillers for Nasolabial Folds
Dermal fillers can restore volume and structural support in selected patients with prominent nasolabial folds. However, treatment does not necessarily mean injecting filler directly into the deepest part of the fold. If changes in the cheek or midface contribute to the nasolabial fold, the doctor may assess whether restoring support in these areas could improve the appearance of the fold. In other cases, carefully placed filler around the nasolabial region may be appropriate.
The treatment approach depends on the individual's facial anatomy, volume distribution and severity of the fold. Different filler materials have different properties. Hyaluronic acid fillers, for example, use a substance naturally found in the body and can provide temporary volume and structural support. Certain injectable materials can also stimulate collagen production.
The amount, placement and type of filler should therefore be selected according to the individual's facial structure and treatment goals rather than using the same technique for every nasolabial fold.
How Long Do Dermal Fillers Last?
Dermal filler results are temporary. How long they last depends on several factors, including the type of filler, treatment area, amount injected, individual metabolism and product characteristics. Results may last several months or longer depending on the product and individual.
Temporary swelling, redness, tenderness or bruising can occur after treatment. Although many people return to normal daily activities shortly afterwards, recovery and side effects vary between individuals. As with any injectable treatment, fillers also carry less common but potentially serious risks, so a qualified medical practitioner should assess suitability and perform the procedure.
Skin Tightening Treatments for Nasolabial Folds
When skin laxity and reduced tissue support contribute to prominent nasolabial folds, skin tightening treatments may form part of the treatment approach.
Depending on the individual's condition, treatment may include technologies such as fractional radiofrequency, RF microneedling or ultrasound-based treatments.
These treatments deliver controlled energy to targeted tissue depths to stimulate collagen remodelling and improve skin firmness over time.
However, skin tightening treatments do not replace lost facial volume. If both structural volume changes and skin laxity contribute to the fold, a doctor may consider a combination approach.
Which Nasolabial Fold Treatment Is Suitable?
The depth of the fold alone does not determine the appropriate treatment. A medical assessment should look at the face as a whole and determine whether the nasolabial fold mainly reflects midface volume changes, skin laxity, skin quality, facial anatomy or a combination of these factors.
Understanding what creates the fold allows the doctor to choose a treatment approach that addresses the underlying contributing factors rather than simply treating the visible line.
