Nasolabial folds are the lines that run from the sides of your nose to the corners of your mouth. Many people call them smile lines or laugh lines. Everyone has them, but they become deeper as we age.
When the skin loses collagen and firmness, these folds can make the face look tired. The good news is that there are effective ways to reduce their appearance. Dermal fillers are one of the most trusted treatments recommended by aesthetic professionals.
In this guide, we explain what nasolabial fold fillers are, how they work, and what results you can expect. You will also learn about the benefits, possible side effects, and aftercare. This will help you decide if it is the right treatment for you.
Nasolabial Fold Filler Treatment Explained
Dermal fillers are injectable substances used to smooth facial lines and wrinkles. They add volume beneath the skin, helping the area appear plumper and more refreshed.
As we age, the skin produces less collagen and elastin. These are the proteins that keep our skin firm and supple. Fillers help restore lost volume and can also support the skin’s natural collagen production over time.
The following hyaluronic acid fillers are approved for the treatment of nasolabial folds:
Bellafill
Belotero
Juvéderm
Prevelle Silk
Restylane
Revanesse Versa
A dermatologist may also recommend other options such as calcium hydroxylapatite (Radiesse) or poly-L-lactic acid (Sculptra), depending on your skin type and the depth of your lines.
Once the right filler is chosen, the practitioner injects it at precise points along the nasolabial folds. The results are visible almost immediately. Over time, the body naturally breaks down the filler.
Most treatments last between 6 and 18 months, depending on the product used and your skin’s metabolism.
Benefits of Nasolabial Fold Fillers
It is often recommended to choose fillers for nasolabial folds over surgery because the results are quick, natural, and achieved without invasive procedures.
Fillers let you refresh your appearance without the risks, cost, or long recovery associated with surgical options.
Key benefits include:
- Immediate improvement
- Natural look
- Minimal side effects
- No recovery time
- Makeup allowed

- Custom approach
When performed by an experienced aesthetic practitioner, results are smooth and balanced. Your skin will appear more hydrated, lifted, and youthful while maintaining your natural expressions.

Nasolabial Fold Filler Risks and Potential Side Effects
Nasolabial fold filler treatments are considered safe when performed by a qualified practitioner. However, as with any cosmetic procedure, there are possible risks and mild side effects to be aware of.
Most are temporary and resolve on their own within a few days.
Common side effects include:
Mild swelling or redness at the injection site
Slight bruising or tenderness
Small lumps that usually smooth out within a few days
Less common but possible risks include:
Infection if the treated area is not kept clean
Allergic reaction to the filler material
Uneven results or filler migration
To reduce these risks: Always follow aftercare advice carefully, avoid touching the area for a few hours, and skip intense exercise or saunas for at least 24 hours.
If any swelling, pain, or discolouration lasts longer than expected, contact your practitioner immediately.
Results and Aftercare
Results from nasolabial fold fillers can be seen almost immediately. The treated area looks smoother, with lines appearing softer and less defined. Full results become visible once any minor swelling settles, usually within a few days.
Typical results:
A more refreshed and youthful appearance
Softer and more balanced facial contours
Natural movement and expression preserved
Aftercare tips:
Avoid touching or massaging the treated area for at least 24 hours
Stay away from intense exercise, saunas, and hot showers for the first day
Apply a cold compress if mild swelling occurs
Avoid alcohol and blood-thinning medication for 24 hours unless prescribed
Light makeup can be used after treatment to cover redness
Keep the skin clean and moisturised
Results can last between 6 and 18 months, depending on the filler type, your skin, and your lifestyle. Regular maintenance treatments help preserve the results over time.
Reasons for Nasolabial Folds
Nasolabial folds are a normal part of facial anatomy, but several factors can make them more visible over time. Understanding the causes helps you choose the right treatment and prevent them from deepening further.
Main reasons include:
- Ageing: As we age, collagen and elastin levels drop, leading to less skin support
- Loss of facial fat
- Sun exposure: UV rays damage collagen and speed up skin ageing.
- Facial expressions: Smiling and laughing cause repeated movement in the same area, which deepens the lines.
- Genetics: Some people are naturally more prone to prominent nasolabial folds.
- Lifestyle factors: Smoking, dehydration, and poor skincare habits can make folds appear earlier and more visible.
While nasolabial folds are a normal feature, fillers can help restore lost volume and make the skin appear smoother and more youthful.
Other Procedures That Can Soften Nasolabial Folds
Dermal fillers are one of the most effective ways to reduce nasolabial folds, but they are not the only option. Several other treatments can help improve skin texture, boost collagen, and create a smoother appearance.
Popular alternatives include:
Botox
Helps relax nearby muscles to reduce the pulling motion that deepens folds. Often used with fillers for balanced results.
Profhilo
A hyaluronic acid-based treatment that hydrates the skin and improves firmness without adding volume.
Microneedling
Stimulates collagen production by creating tiny micro-injuries in the skin, improving texture and elasticity.
Laser resurfacing
Targets fine lines and sun damage while encouraging new collagen formation.
Chemical peels
Remove dead skin cells and improve overall skin tone for a fresher look.
Thread lift
Uses dissolvable threads to gently lift sagging skin and soften the folds.
Your practitioner may recommend combining treatments for the best outcome. A tailored plan ensures the most natural and long-lasting improvement based on your skin type and goals.
Final Thoughts
Nasolabial fold fillers are a safe and effective way to soften deep smile lines and restore a more youthful look. The treatment is quick, minimally invasive, and delivers results that appear natural while maintaining your facial expressions.
Choosing an experienced aesthetic practitioner is key to achieving smooth, balanced results. A professional will assess your skin, recommend the right filler, and ensure your treatment is tailored to your facial structure.
If you are looking to refresh your appearance without surgery, nasolabial fold fillers may be the ideal choice. With proper care and maintenance, you can enjoy smoother, lifted skin and a more confident look that lasts.
