What Are the Lines on the Side of the Mouth and What Can We Do About Them?

Lines on the side of the mouth, also known as Nasolabial Folds or Marionette Lines, are the two vertical lines of mouth wrinkles. Nasolabial Folds, also called laugh lines, look like parentheses and run from the nose to the mouth. Marionette Lines appear on either side of your lips and run down to the chin.

The cause of these lines is a combination of aging, genetics, sun exposure and facial expressions like frowning or smiling. While these lines may not be as prominent as other signs of aging such as crow’s feet or forehead wrinkles, they can still add years to one’s appearance.

There are several treatments available to reduce the appearance of these lines and restore a more youthful look. Let’s talk about what causes lines on the sides of the mouth and how you can treat them effectively with both non-invasive surgical procedures, and at home remedies.

What Causes Lines on the Side of the Mouth?

Skin Aging:

As we age, we lose collagen and elastin in our skin, two proteins that help our skin remain supple and wrinkle-free. This loss of this skin elasticity often causes our skin to sag and, in turn, creates lines and wrinkles around the mouth. Smile lines can be particularly noticeable because the skin around our mouth is thinner and more prone to developing wrinkles.

Sun Damage:

The sun’s UV rays can penetrate our skin and cause damage to our collagen and elastin fibers. Over time, this damage can lead to lip wrinkles, including smile lines. To prevent sun damage, wear sunscreen daily with at least SPF 30 and reapply often throughout the day, especially if you’ll be spending extended time outside, even in the winter, or even driving in your car!


Smoking has numerous detrimental effects on your skin, including the formation of wrinkles. When you smoke, it reduces blood flow to your skin, decreasing the amount of oxygen and nutrients your skin can receive. This deprivation of vital nutrients can lead to wrinkles, including smile lines.

Overuse of facial muscles:

You may have heard the phrase “resting bitch face” – a facial expression that looks angry or irritated when the face is relaxed. This expression, along with other facial expressions that create tension around your mouth, can cause the muscles around your mouth to be overused, leading to wrinkles.


Unfortunately, some people may be predisposed to developing smile lines due to their genetics. If your parents or grandparents had deep smile lines, you may be more likely to develop them as well. 

Treatment Options

The following services provided by Ageless Aesthetics by HB Walsh can effectively improve the appearance of side mouth lines:

Jet Plasma Skin Tightening

This advanced treatment directs plasma energy to target and stimulate collagen production deep within the skin layers. This stimulation enhances collagen levels, and as a result Jet Plasma Skin Tightening helps to improve skin elasticity and firmness. Nasolabial Lines, Marionette Lines, and Peri-Oral Wrinkles become less pronounced, and the overall texture of the skin is rejuvenated. This treatment is customarily performed to the entire face, so it also assists in minimizing fine lines and wrinkles in other areas.

Plasma Fibroblast Skin Tightening

Plasma Fibroblast Skin Tightening is specifically designed to address loose and sagging skin. By utilizing plasma energy to create controlled micro-injuries on the skin’s surface, sublimating the skin and triggering the skin’s natural healing response, encouraging collagen synthesis. As collagen rebuilds, the skin becomes tighter, reducing the depth of lines and creating a more youthful appearance.

BioRePeel Treatment

The BioRePeel treatment is a unique combination of gentle exfoliation, peeling, and revitalization. It involves applying a special solution to the skin, which contains a blend of acids, vitamins, and other active ingredients. This solution helps to exfoliate the top layer of dead skin cells, stimulating cell turnover and collagen production.

In the context of lines around the mouth, the BioRePeel treatment can be beneficial in multiple ways. The exfoliation process helps to smooth the skin’s texture and reduce the appearance of fine lines and wrinkles. The infusion of vitamins and nutrients encourages skin rejuvenation, promoting a more youthful appearance. Additionally, the treatment enhances the skin’s overall tone and radiance, making lines less noticeable.

Hyaluron Pen Treatments

The Hyaluron Pen treatment involves delivering hyaluronic acid into the skin using air pressure, plumping up the targeted areas. While it’s often used for lip enhancement, it can also be effective in reducing the appearance of perioral wrinkles. By introducing hyaluronic acid through the skin, the treatment can help fill in the lines, making them less noticeable and creating a smoother appearance.

Microchanneling or Microneedling

Microchanneling, a procedure similar to microneedling, promotes collagen and elastin production through the creation of controlled micro-injuries. This stimulation leads to a healing cascade which encourages skin regeneration, reduces the appearance of fine lines and wrinkles, including those around the mouth. Microchanneling encourages the skin to become firmer and more supple, effectively minimizing the depth of lines over a series of treatments.

Dermaplaning is an exfoliating treatment that involves using a scalpel to gently remove the top layer of dead skin cells and vellus facial hair (peach fuzz). By exfoliating the skin, dermaplaning promotes cell turnover, revealing smoother, fresher skin underneath. This can help to soften the appearance of lines and facial wrinkles, while also improving the overall texture and tone of the skin.

Each of these services offered by Ageless Aesthetics by HB Walsh contributes to enhancing the appearance of facial lines by targeting different aspects of skin health. Whether through collagen stimulation, skin tightening, filling, or exfoliation, these treatments collectively work towards achieving a more youthful and rejuvenated look for the skin around the mouth area.
