Laugh lines are deemed attractive as they may present the cheerful and jovial state of oneself. However, with aging and certain other reasons, they become more visible and the creases around the mouth get deeper, arousing the signs of an aged person. That’s the moment where one thinks to get rid of the laugh lines. 

What are Laugh lines?

Nasolabial folds, commonly referred to as laugh lines or smile lines, are the lines or creases that run from the corners of the nose down to the corners of the mouth. These lines become more prominent as we age due to the loss of collagen, elastin, and facial fat, as well as the repetitive muscle movements involved in smiling, laughing, and talking.

What are the Causes of Nasolabial Folds?

Although nasolabial folds can also appear in children, the actual cause of their development is still not fully understood and requires further research. However, in the majority of cases, the following causes contribute to making visible nasolabial folds:

  • Aging
  • Constant exposure to the sun
  • Loss of elastin and collagen in the skin
  • Weight gain or weight loss

Treatments for Smile Lines

There are several treatment options to address nasolabial folds (smile lines), depending on the depth and severity of the lines. The best 5 ways to reduce nasolabial lines include:

Botulinum Toxin Injections 

Commonly known as Botox, commonly used for dynamic wrinkles, works by temporarily relaxing the muscles responsible for these movements, which in turn softens the lines and reduces their appearance. 

Dermal Fillers

For deeper laugh lines or nasolabial folds, dermal fillers, which are gel-like substances injected into the skin to fill in the creases and restore volume, are typically more effective. As always, it’s important to consult with a qualified medical professional to determine the best course of action for your specific needs.

Non-Surgical Treatments for Reducing Laugh Lines

Skin tightening procedures like laser therapy, ultrasound therapy, and radiofrequency (RF) treatments can help reduce the appearance of laugh lines or nasolabial folds. These non-invasive treatments work by stimulating collagen production and tightening the skin, which in turn can make the lines less visible. Here’s a brief overview of these methods:

Laser Therapy

Fractional laser resurfacing and non-ablative lasers stimulate collagen production in the skin, leading to a tightening effect. This can help reduce the appearance of laugh lines and improve overall skin texture.

Ultrasound Therapy

Ultrasound-based treatments, such as Ultherapy, use focused ultrasound energy to heat the deeper layers of the skin, stimulating collagen production and resulting in a tightening effect. This can help reduce the appearance of laugh lines and other signs of aging.

Radiofrequency (RF) Treatments

These treatments use radio waves to heat the deep layers of the skin, promoting collagen and elastin production. This leads to a tightening and firming effect, which can help reduce the appearance of laugh lines and other wrinkles.

Topical Treatments

Topical treatments containing active ingredients like vitamin C can also help in reducing the appearance of laugh lines, although their effects might be less dramatic compared to injectables or more invasive procedures. 

Cosmetic Surgery

Cosmetic surgeries, such as facelifts and cheek lift, can also generate positive results and reduce nasolabial lines for a certain period of time. However, these are surgical procedures and require designated pre-op and post-op care. Consequently, one can also face common complications like bruising, swelling, or pain in the treatment area for a certain period. 


It’s important to note that individual results may vary, and multiple sessions may be required to achieve the desired results. Additionally, these treatments may not be suitable for everyone, so it’s crucial to consult with a qualified medical professional before undergoing any skin tightening procedure.

Exercises for Reducing Laugh Lines

There are some facial exercises that may help to tone the muscles around the mouth and reduce the appearance of laugh lines. Although the effectiveness of facial exercises for reducing laugh lines might be limited or vary among individuals, some studies suggest that they can have a positive effect on facial muscle strength and appearance. Here are a few facial exercises that may help:

Smile exercise: This exercise involves smiling as widely as possible, then holding the smile for a few seconds before relaxing the face. Repeat this exercise several times throughout the day.

Cheek lift exercise: Pucker your lips together, then smile with your lips still pursed. Hold this position for a few seconds, then release and relax the face.

Tongue press exercise: Press the tip of your tongue against the roof of your mouth, then smile and hold for a few seconds before releasing.

While doing these exercises, be gentle and avoid overdoing it. Additionally, you need to have realistic expectations from the process.

How to Prevent Nasolabial Folds?

There is no certain way one can prevent nasolabial folds, as they are likely to appear at some stage. However, lifestyle factors such as maintaining a healthy diet, staying hydrated, and not smoking, which can help delay the appearance of nasolabial folds. If you are still on the quest to find preventive measures, try to sleep on your back as much as you can. Similarly, use sunscreen to protect your skin from UV rays.
