Nasolabial Fold Wrinkles

What are Nasolabial Fold Wrinkles?

Nasolabial fold wrinkles, sometimes referred to as “smile” lines, extend from each side of the nose to the corners of the mouth, and are a common consequence of facial aging. These wrinkles occur naturally as a result of age-related facial volume imbalance, and can deepen as time passes.

Nasolabial folds may be more pronounced and can make you appear older than you are. However, there are treatments designed and available to soften the appearance of these wrinkles and restore a more youthful look.

What Causes Nasolabial Fold Wrinkles?

As we age, the production of elastin and hyaluronic acid begins to decline. Elastin and hyaluronic acid are important components of the skin that provide strength, shape and texture. Without them, the skin starts to sag and wrinkles begin to form.

When volume is lost in the face, skin around the nose and mouth can start to droop, causing nasolabial fold wrinkles to form and deepen.

How to Treat Nasolabial Fold Wrinkles

The following are some of the most common treatments to soften the appearance of nasolabial fold wrinkles:

  • Injectable treatments, such as Botox and dermal fillers.
  • Laser resurfacing.
  • Microneedling.
  • Platelet-rich plasma (PRP).
  • Chemical peels.

Each of these treatments will produce different results, and the best option for you will depend on your particular needs and expectations.


Nasolabial fold wrinkles are a common side effect of facial aging. Though wrinkles themselves cannot be prevented, there are treatments available to reduce their appearance and restore a more youthful appearance. Before beginning any treatment, be sure to talk to your physician or skincare professional to determine the best option for you.
