The Hidden Story Behind Those Changes in Your Face
Have you noticed those gentle creases forming from the base of your nose down toward the corners of your mouth? They have many names in a dermatologist's office—nasolabial folds, melolabial folds—but most people simply call them smile lines. And for many, they become one of the first visible signs of aging that stirs a quiet unease. I have seen this happen countless times in consultations, even with people in their thirties and forties. It is rarely a deep, dramatic change at first, but it is the moment when someone looks in the mirror and thinks, "I do not love what is happening to my face."
Before we explore what can truly help, we must first understand why these lines form. Without understanding the root cause, no solution will ever be lasting or satisfying. And the causes, as it turns out, are far more complex than most people realize.
Why Your Face Changes: The Many Causes
The first cause is the most obvious one: smiling. Every time you smile, you create a crease along that line. Over a lifetime, that repeated movement etches itself deeper into the skin. But that is only the beginning.
A far more significant factor is gravity and the descent of your facial tissues as you age. Your skin naturally loses elasticity. It becomes more lax over time. As it starts to fall, those lines become emphasized. This is a hallmark of aging: the shape of your face shifts. In youth, volume sits in the top half of the face, giving a lifted, balanced look. As time passes, that volume descends, accumulating in the lower face. You see jowling along the jawline, and those nasolabial folds become much worse.
But there is another, less visible cause: volume loss in the bone itself. This is especially common in women. As we age, we lose bone density in the skull, particularly in the maxillary bone—the bone that gives you your cheekbone and supports the base of your nose. When that bone shrinks, the nose can start to fall back into the face, which dramatically accentuates those lines.
And then there is weight loss. The fat in your face acts as a natural support structure. When you lose significant weight—which has become far more common in recent years—that support diminishes, and smile lines become much more pronounced. Many people who have undergone major weight loss report feeling that their face looks older, and these folds are at the center of that complaint.
Genetics also play a powerful role. How your face ages is largely determined by your DNA. Some people are simply more prone to developing these lines than others. And, of course, the quality of your skin matters immensely. As skin ages, it thins and becomes more dehydrated, making it vulnerable to lines settling in. UV radiation and smoking accelerate this process significantly.
One often-overlooked cause is side sleeping. When you sleep on your side, you smash your face into a pillow. If a crease is already forming along your smile line, that is exactly where your skin will collapse. You end up etching that line deeper for six or more hours every single night. Many people have never considered this until it is pointed out, and then it suddenly makes perfect sense.
What You Can Do at Home: Small but Meaningful Steps
The interventions you can do at home are not for fixing deep, established folds. They are for improving the quality of your skin so it becomes less prone to creasing in the first place.
Two things are absolute holy grails: sun protection and topical retinoids. These are the most powerful tools you have for keeping your skin as supple and youthful as possible. The more collagen you have in that delicate area between your cheek and upper lip, the less prone it is to creasing and folding over time.
If you are looking for at-home devices, a red light LED mask can be a wonderful investment. The red and near-infrared light stimulates collagen synthesis within the skin. There is a convenience to doing this at home that can be very motivating. Similarly, microcurrent devices, like the NuFace, have helped some people achieve modest tightening around the cheeks and jawline. Anytime you lift and tighten the cheeks, you alleviate the folds, because those folds are a symptom of descent. But I always remind people: you must know yourself. These devices require consistent daily use to maintain results, and those results are modest. It is about little incremental improvements every single day.
Facial massage and gua sha can also be genuinely helpful, especially for people who tend to be puffy. Constant fluid buildup in the face weighs the tissues down and emphasizes these lines. By moving that fluid up and out on a regular basis, you can improve the appearance of the folds. This will not eliminate an entire fold, but small improvements are the name of the game when it comes to at-home care. And when you stretch and move the skin away from the crease, you also prevent that fine line from getting etched deeper.
One of the most practical changes you can make—if you can manage it—is learning to sleep on your back. I say this as someone who has never been able to do it myself. But if you can train yourself, it helps not just with smile lines but with creases on your chest and neck as well. If side sleeping is non-negotiable for you, consider wearing silicone patches along your smile lines at night. Silicone patches act as a support mechanism so that when you sleep on your side, your skin does not fold and crease. You can use products made for the face or simple silicone tape from online retailers. It is a small thing that can make a real difference.
But please, do not obsess over these at-home interventions. Do your best, but live your life. There is no joy in constantly trying to smooth out your face or prevent every line. That is a miserable way to exist.
In-Office Treatments: What Actually Works
Now let us talk about what you can do in a doctor's office, because that is often what people are truly curious about.
First, let me address a common question: Can Botox fix smile lines? The answer is no. Botox relaxes muscles. The reason this line exists is because you smile. If I injected Botox to prevent you from smiling, you would look like you were having a stroke on both sides of your face. The only way to truly avoid emphasizing these lines is to never smile, and that is not a practical solution.
What people often mean when they ask about Botox is filler—something that takes up space and volumizes the tissue to plump the area. Filler absolutely has a place in correcting nasolabial folds, but it must be used with extreme conservatism. The primary cause of these folds is descent of the tissue, not a lack of volume in the fold itself. If you simply fill the fold with several syringes of filler, you can make the lines disappear completely. But when you step back and look at the entire face, you will not look better. You will look puffy, and some people describe that look as "simian" or "monkey-like." No patient has ever walked into my office and asked to look like a monkey.
The key principle is this: we do not treat features—we treat faces. Any cosmetic intervention must be evaluated for how it affects the whole face. These smile lines are a symptom of something greater: the descent of your facial tissues. If you only treat the symptom without addressing the underlying cause, you will never get where you want to go. Filler can be placed along the folds with a careful technique that maintains a natural appearance. The goal is not to completely eliminate creases or shadows, but to lessen how harsh they are.
There is also a technique of placing filler in the cheeks to create an illusion of lifting the tissues. But this must be done with a discerning eye. It is only appropriate for people who have flatter cheeks or less prominent cheekbones. If a woman already has full, beautiful cheeks and high cheekbones, adding filler there will not lift the folds—it will just create alien or feline-looking cheeks. However, if someone has lost volume throughout the face—through age or rapid weight loss—restoring volume to the temples, cheeks, and the area in front of the ear can bring balance to the entire face. When you step back and look at someone whose face has been rebalanced in this way, the smile lines become less prominent. They are still there, but they are no longer a distractor or a detractor. This is the thoughtful, strategic approach that an experienced injector provides.
Another option I use often, especially for younger patients in their thirties or early forties who are just starting to see a line, is Sculptra. Sculptra is a biostimulatory filler that stimulates collagen in the skin. By placing it in the fold and throughout the face, you give the skin a collagen boost that makes it less prone to falling and sinking over time. This helps not just with smile lines but with preventing the many other lines and creases that inevitably come with aging.
For early signs where the line is just beginning to etch into the skin, resurfacing procedures can be very helpful. Laser resurfacing and microneedling build collagen in the skin, which can lessen the line. But these work only on the superficial tissues—they are not effective for deep folds.
I want to address radiofrequency microneedling specifically, because so many people have been told it will lift and tighten the skin. Devices like Morpheus 8 or Profound are marketed incredibly well. But in my experience and in conversations with dermatology colleagues across the country, very few of us have seen significant tightening from these devices. I have one in my office, and I think it is wonderful for refining pores, improving acne scarring, and enhancing texture. But it will not lift and tighten the skin. I have had countless patients come to me after spending thousands of dollars on radiofrequency microneedling in hopes of lifting their jowls, marionette lines, or nasolabial folds, and they have seen no significant benefit. These companies market their devices as filling that niche because everyone is desperate for something non-surgical that truly lifts. But the reality is, these devices do not deliver that result.
On the other hand, skin tightening devices like Sofwave or Thermage do have a small place, particularly for people who have excessive volume in the face. If you have heavy jowls and larger cheeks that are weighing down the face and creating those lines, these devices can provide some local fat reduction and modest tightening when used with the right settings. But the improvement is subtle.
By far, the best non-surgical option for improving smile lines is something that actually lifts the tissue. Many patients come in and use their hands to pull back the skin at the periphery of their face. Their smile lines disappear, and they say, "I just want that." Unfortunately, in dermatology, we do not have a tool that can provide multiple millimeters of lift—let alone a centimeter of lift—in a non-invasive way. Nothing has been shown to do that.
Threads are marketed as having that ability. You do see an immediate lift, and for a few weeks, you might look amazing. But in my experience, the lift is temporary. The skin inevitably sags back down, usually quite quickly. Patients end up disappointed. If threads cost a few hundred dollars and were not invasive, that might be acceptable. But getting threads is actually a big deal, and it is expensive. For most people, it ends up not feeling worth it.
And so we come to the honest answer that nobody really wants to hear: the best way to get rid of deep smile lines is a surgical facelift. I know people come to a dermatologist hoping for non-invasive solutions, and I have shared many of them. But the reality is, because smile lines are so driven by the descent of tissue, the only way to truly fix them is to pull the tissue back up to where it started. If there were amazing, non-invasive alternatives that did exactly what a facelift does, facelifts would not exist. Nothing rivals what a facelift can accomplish.
That said, I would not recommend a facelift for smile lines alone. It is best suited for people who are also noticing jowling, sagging in the neck, and other signs of significant descent across the face. A facelift does not last forever, but of all the interventions I have discussed, it has by far the longest-lasting effect because it actually replaces displaced volume where it belongs.
Many people will say, "I am never getting a facelift." And that is completely fine. Getting a facelift is not something everyone can do, or wants to do, or can afford, or wants to take the risk of. There are many other things we can do to improve these lines. But it is important to be honest: nothing will give you the same result.
Your face tells a story—of smiles shared, of years lived, of the unique way you have moved through the world. Those lines are part of that story. The goal is not to erase them completely, but to feel comfortable and confident in your own skin. Whether you choose a simple morning routine, a subtle in-office treatment, or something more involved, the most important thing is that you do it for yourself, with understanding and with peace.
