Nasolabial Folds vs. Smile Lines from Your 30s: Differentiating Confusing Wrinkles

Hello,

This is SNU Plastic Surgery in Cheongdam.

Today, we will explore the difference between

nasolabial folds and smile lines,

concerns many people face from their 30s,

and introduce the correct improvement methods

for each!

✨ Nasolabial Folds VS Smile Lines, what's the difference?

Many people visit us saying, ‘I have nasolabial folds!’

However, upon closer diagnosis,

it is often not true nasolabial folds

but rather smile lines.

📍 True Nasolabial Folds (Aging-related)

Causes

Decreased skin elasticity, sagging facial fat layer,

absorption of the upper jawbone, etc.

Characteristics

Wrinkles that appear due to actual

sagging of skin and tissue

Onset

Mainly become prominent

from the mid-40s onwards

📍 Smile Lines (Expression-related)

Causes

Depressions formed by the movement of mouth muscles

Characteristics

An emphasized boundary line

between the perioral tissue and cheek tissue

Onset

Can become prominent

even from the 20s to 30s

✨ How do the improvement methods differ for each?

📍 Improvement Methods for Aging-related Nasolabial Folds

Various methods such as mid-face lift surgery, Ultherapy,

filler injections, and thread lifts can be chosen

depending on individual conditions,

and a certain degree of improvement can be expected.

📍 Improvement Methods for Smile Lines

Smile lines are often difficult to sufficiently improve

with the surgeries and procedures mentioned above.

✨ Advice for Younger Individuals

When younger individuals in their 30s

visit us concerned about nasolabial folds,

we advise them as follows:

The changes you are seeing now are closer to smile lines than true nasolabial folds. Therefore, it is advisable to consider 1-2 less invasive methods lightly rather than aggressive surgery or procedures.
✨ Why should we approach it ‘lightly’?

✅ If filler injections are too heavy,

they can have the counterproductive effect

of reducing natural facial expressions.

✅ If too many procedures are received,

the economic loss can be significant

compared to the effect.

✅ Invasive methods like surgery

can leave permanent scars on a young face,

so they must be considered carefully.


Your precious face,

be careful not to harm its natural charm

with excessive procedures that are not appropriate for your age!

It is most important to accurately differentiate whether your current wrinkles are truly aging-related

nasolabial folds or smile lines,

and then choose the appropriate method.

Always consult sufficiently with a specialist

to choose the method that is right for you!😊
