What Causes Deep Nasolabial Folds? How to Fix Them and Can You Get Nasolabial Fold Fillers?

Want to get nasolabial fold fillers because deep smile lines are bothering you, making you lose confidence every time you smile? Are you still wondering what nasolabial fold fillers are, whether they hurt, and how safe they are? If so, we will take you through every detail regarding this dermal filler treatment.
Deep nasolabial folds significantly impact self-confidence. Besides making the face look older than its actual age, they make you look exhausted, dull, and even make pores appear enlarged. If you are facing this issue and want to know how much dermal fillers can help restore tight, firm, non-sagging, and youthful skin, along with how to prepare yourself, let's explore all the details in this article.
What Causes Deep Nasolabial Folds (Smile Lines)?
Deep nasolabial folds result from multiple factors and usually become noticeably visible starting from the age of 25 onwards. The main causes can be summarized into 4 key factors:
1 Behavioral Patterns: Frequent smiling or laughing continuously pulls the facial muscles around the nasolabial fold area, eventually creating deep structural lines.
2 Bone Resorption Around the Nasolabial Area: Commonly observed in individuals aged 20–30, where subtle bone recession occurs around the piriform aperture, leading to mild to moderate creases.
3 Infraorbital (Under-Eye) Bone Resorption: Commonly seen in people over 30 years old as the bone beneath the eyes resorbs, causing mid-face fat pads to sag and rest directly above the nasolabial area, deepening the folds.
4 UV Radiation: Sun exposure degrades collagen and elastin fibers while drying out skin hydration. When the face loses elasticity, cheek tissue sags further, forming prominent smile lines.
What Is Nasolabial Fold Filler and How Much Can It Help?
Nasolabial fold filler is a non-surgical procedure that involves injecting hyaluronic acid (HA) dermal fillers into deep or sunken folds. The filler binds and holds water beneath the skin layers to plump up the area, restoring a smooth, youthful, and vibrant appearance.
Results are visible immediately post-treatment without surgery or downtime. The procedure carries a high safety profile because hyaluronic acid is naturally produced by the human body, minimizing allergic reactions, and degrades naturally over time without leaving harmful chemical residues.
How Many CCs of Filler Are Needed for Nasolabial Folds?
The volume of filler required depends on individual fold depth:
- Mild to Moderate Folds: Physicians typically recommend approximately 1–2 CCs.
- Severe or Deep Folds (Older Patients): Physicians will assess and increase the CC volume on an individual basis. In some cases, combining filler injections with energy-based skin tightening treatments may be recommended for optimal results.
Who Is Suitable for Nasolabial Fold Fillers?
- Individuals with deep nasolabial folds or visible smile line wrinkles.
- Individuals with sagging cheek tissue who look older than their age.
- Individuals experiencing under-eye and mid-face bone resorption causing heavy fold shadows.
- Individuals wanting a youthful facial lift.
- Individuals with severe skin dryness leading to fine lines around the mouth.
- Individuals seeking non-surgical facial rejuvenation.
How to Prepare Before and Take Care of Yourself After Filler Injections
Before Treatment Guidelines
- Stop blood-thinning medications and supplements: Refrain from NSAIDs, aspirin, and health supplements affecting blood clotting 1 week prior to the procedure.
- Avoid exfoliants: Stop using active chemical exfoliants and facial scrubs.
- Avoid strenuous exercise: Stop heavy workouts 1 day before injection to normalize blood circulation.
- Avoid alcohol: Abstain from alcoholic beverages at least 1 day before to reduce swelling and bruising.
After Treatment Guidelines
- Limit facial expressions: Avoid excessive facial movements for the first 3 days.
- Do not touch or massage the area: Avoid rubbing, touching, or pressing the injection site to prevent filler displacement.
- Avoid intense heat: Stay away from direct sunlight, open flames, or hot environments, as high temperatures hinder filler settling.
- Avoid alcohol: Abstain from alcoholic drinks to prevent localized inflammation.
- Stay well-hydrated: Drink plenty of clean water to allow the hyaluronic acid filler to expand and maintain its plump shape.
- Postpone facial treatments: Avoid facial massages, treatments, or skin lasers for 1 month post-procedure.
Summary: Reclaiming a Youthful and Lifted Face
Nasolabial fold fillers offer an effective, safe, and immediate non-surgical solution to correct deep smile lines and restore mid-face volume. Following proper pre- and post-treatment protocols ensures long-lasting, natural-looking aesthetic results.

Low Ferritin Symptoms: What to Watch For in 2026
Low ferritin appears before anemia does. Symptoms begin when iron stores drop, sometimes months before red blood cell count falls. Many people attribute fatigue or hair thinning to stress or age when the cause is measurable and correctable. A ferritin test is a simple blood test, yet it is often missing from a routine check-up.

Metformin Longevity: Evidence and Practical Guidance
Metformin longevity refers to the hypothesis that metformin, a first-line diabetes medication, may slow biological aging and extend healthspan in non-diabetic adults. The mechanism centers on AMPK activation, mitochondrial modulation, and autophagy induction. Human trials are ongoing, but retrospective cohort data and primate studies suggest measurable effects on aging biomarkers.

MCHC Blood Test: Reference Ranges and What It Measures
The mchc blood test measures the mean corpuscular hemoglobin concentration inside your red blood cells. It reports the average amount of hemoglobin per unit volume of red cells, expressed in grams per deciliter. This metric is derived from two other values: total hemoglobin and hematocrit. The calculation divides hemoglobin by hematocrit and multiplies by 100.
