Nasolabial Fold (Smile Lines)

1. What are nasolabial folds?

Everyone has nasolabial folds. These are the natural lines that extend from the sides of the nose to the corners of the mouth.

They're commonly called smile lines or laugh lines because they become more visible when we smile. As we age, these lines often become deeper and remain visible even when the face is relaxed.

2. Why do I have deep smile lines?

Smile lines become deeper because several things happen over time:

• Cheek volume decreases.

• Facial fat gradually moves downward.

• Collagen and elastin decline.

• Skin becomes thinner.

• Facial bones provide less support.

It is usually not caused by just one problem.

3. At what age do nasolabial folds appear?

Most people begin noticing mild smile lines in their 30s, when collagen production starts to slow.

During the 40s and 50s, changes in facial fat, skin elasticity, and bone support often make the folds more noticeable.

However, genetics can make them appear earlier.

4. Why do some young people already have smile lines?

Not all smile lines are caused by aging.

Some people naturally have:

• thinner skin

• stronger facial expressions

• prominent cheek anatomy

• inherited facial features

This is completely normal.

5. How can I prevent nasolabial folds?

Although you cannot stop aging completely, you can slow the development of smile lines by:

• Wearing sunscreen daily

• Avoiding smoking

• Maintaining a healthy weight

• Following a consistent skincare routine

• Considering collagen-stimulating treatments before severe aging develops

Prevention is often easier than correction.

6. How can I get rid of nasolabial folds?

There is no single treatment that works for everyone.

The best approach depends on why your smile lines developed.

Some people need more facial support, while others benefit from skin tightening or volume restoration.

7. What is the best treatment for nasolabial folds?

Different causes require different treatments.

8. Can filler completely remove smile lines?

Not always.

In many patients, placing too much filler directly into the fold can create an unnatural or heavy appearance.

Experienced injectors often improve the cheeks and midface first, allowing the smile lines to soften naturally.

9. Do facial exercises or skincare products really work?

A good skincare routine can improve skin quality and hydration, but it cannot rebuild lost facial volume or lift descended tissues.

Similarly, facial exercises may improve muscle awareness, but there is limited evidence that they significantly reduce established nasolabial folds.

10. How do DORE clinic choose the right treatment?

Rather than looking only at the smile lines, experienced doctors evaluate your entire face, including:

• Skin quality

• Cheek volume

• Facial support

• Degree of sagging

• Overall facial balance

A personalized treatment plan almost always produces the most natural and long-lasting results.
