I’m a Plastic Surgeon. These Are the Cosmetic Treatments I’d Never Do.

As a plastic surgeon, people constantly ask me about the latest and greatest in beauty: what fillers, lasers, surgeries, and serums I recommend. But the question nobody thinks to ask, and the one I think matters just as much, is what I would never do.

As a board-certified plastic surgeon in New York City, skin scientist, and founder of Dr. Devgan Scientific Beauty, I have spent my life studying the face and body from the inside out. After more than a decade operating on faces and bodies, treating thousands of patients, and building a skin care line grounded in the same science I use in the operating room, I have developed firm opinions about the things I will not touch. These are not judgments about other people’s choices. They are the lines I personally will not cross, for reasons that are clinical, aesthetic, and earned through experience.

Reduce the Face to a Looksmaxxed Algorithm

We are living in an era where every face can be scanned, scored, filtered, and analyzed by artificial intelligence, where an algorithm can identify asymmetry in the brows, millimeters of difference in the eyelids, uneven lip volume, nasal deviation, jawline angles, facial thirds, facial fifths, and every departure from some theoretical ideal. That information can be interesting, and sometimes even useful, but it is not the same thing as taste. The face is not a mathematical equation. Beauty is not an algorithm, despite the looksmaxxing content and golden ratio overlays that populate our TikTok feeds.

Some of the most beautiful faces in the world have asymmetries: a stronger dimple on one side, a dominant nose, a brow that is more arched, a smile that tilts to one side. Often they are the very details that make a face memorable, recognizable, and alive. The goal is not to polish away every point of variance until the face becomes a generic textbook ideal. The goal is to understand which details contribute to beauty and identity, and which ones create distraction, heaviness, or disharmony.

The face is not a spreadsheet where every feature can be adjusted independently and still add up to beauty. It is more like a conversation, where the brow changes the way we read the eyes, the midface changes the way we understand fatigue, the neck changes the authority of the jawline, and the skin changes the credibility of everything beneath it. A millimeter in one place can soften a decade in another.

The best results are not the ones that satisfy a formula or flatten every irregularity into sameness. They are the ones where the whole face becomes more coherent, where nothing looks newly purchased. The patient looks rested, alive, and unmistakably recognizable, and surgery disappears into the larger truth of the face.

Let a Trend Near My Face

Aesthetic medicine has fashion cycles, just like clothing does. The difference is that when a trend is integrated into your anatomy, it can be much harder to leave behind. We have seen the eras of bad aesthetic trends come and go: the dramatically overfilled lips, the pillow cheeks, the frozen forehead, the exaggerated “fox eyes,” and the hyper-snatched jawline. Every one of those looks felt modern at the time. Many of them aged poorly, because they were designed for a feed or a filter, not for a living, moving human face. Unlike a hemline, a face cannot simply be let back down, and you can’t restore a distorted smile or stretched tissue to its original architecture.

Operate on Someone Who Is Not Ready

People often assume that a surgeon’s instinct is to operate. In reality, one of the most important decisions a surgeon can make is when not to. I have turned away patients who wanted procedures I could technically and beautifully deliver, because the timing, emotional state, or expectations were not right. Surgery can refine anatomy, restore proportion, and improve confidence, but it cannot get you a job, make someone love you, repair a heartbreak, or solve the deeper problems of a life in transition. Plastic surgery is medicine, not magic.

I am also careful when there is a mismatch between what a patient wants and what their anatomy, tissue quality, healing capacity, or surgical safety can responsibly allow. Not every reference photo can be translated. Not every face or body should be pushed to the edge of what is technically possible. One of my favorite Shakespeare lines is that “discretion is the better part of valour,” and it resonates with me often in surgery. Sometimes the most ethical, protective, and skillful thing I can do in a consultation is say no or not yet.

Give Up on Filler

Filler has become unfashionable to defend. The concern is real, and filler can be overused, misplaced, and misunderstood. That being said, I would never give up on it. The reason is simple: facial aging is not merely about descent; it is also about volume loss. Bone remodels, fat compartments deflate, soft tissues thin, and the face loses some of the internal architecture that once made it look balanced. If you only lift without restoring volume, the result can look tight. If you only fill without respecting descent, the result can look heavy. The most beautiful outcomes usually require both concepts: repositioning what has fallen and replacing what has been lost.

Replacement of lost volume can be achieved with filler or fat grafting, and each has a role. Fat is beautiful for global, soft, biologic restoration. Filler is beautiful for precision: a subtle tear trough, a crisper chin, an elegant nonsurgical rhinoplasty, a more supported lip. The problem is not filler itself but rather using filler as a substitute for judgment. My approach is structural microdroplet placement, the meticulous application of small amounts of filler in anatomically precise planes. When filler is used well, it should look like better light on the face, better proportion, better rest, and better harmony.

Skip Sunscreen

The least glamorous item on this list is also the most evidence-based, and I am going to say it plainly: sunscreen and sun avoidance are the single most powerful antiaging intervention that exists. Not a serum, not a laser, and not a surgery. Skin cancer is the most common cancer in America, with over 1 in 5 people affected by age 70, and over half of Americans have evidence of degenerative skin changes due to UV exposure.

I have operated on thousands of faces, and the single most consistent predictor of how well skin ages is sun exposure history. I have seen 45-year-old faces with the tissue quality of someone 20 years older as a result of decades of unprotected UV exposure. I have seen 60-year-old faces with remarkable skin integrity, almost always belonging to women who took sun protection seriously their entire adult lives. No procedure undoes the cumulative damage of chronic sun exposure. And no cream, however excellent, compensates for the prevention you skipped 10 years ago.

Neglect the Eyes or the Neck

If I could tell people one thing about facial aging, it would be that the eyes and the neck matter more than most people realize. They are the two areas that most powerfully shape how a face is read: the eyes communicate energy and presence, while the neck frames the jawline and often reveals age before the central face.

These changes are subtle, but they are socially powerful. They can make a person look exhausted, stern, or less present, even when she feels completely vibrant. That is why blepharoplasty, brow support, fat grafting, neuromodulators, filler, and laser resurfacing around the eyes can have such a disproportionate impact. The goal is to restore the eyes to their role as the face’s primary instrument of expression.

The neck is equally important, but for a different reason. It is the architectural support for the lower face. The neck is also one of the places where shortcuts are least forgiving. A little filler in the face cannot correct true neck laxity, and overcorrecting the lower face while ignoring the neck can make the result look incomplete. For the right patient, a neck lift, lower facelift, submental liposuction, platysmal work, neuromodulator, or skin-quality treatment can restore the frame of the face in a way that is quiet but transformative.

Anything Overly Hyped

There are many things in aesthetic medicine that are technically possible, heavily marketed, and financially tempting, but that does not mean they are wise. I am cautious about energy-based devices that promise nonsurgical tightening by heating tissue, denaturing proteins, and creating controlled injury beneath the skin because they can be unpredictable. The same heat that may create contraction can also contribute to facial fat atrophy, tissue thinning, contour irregularity, or a hollowed appearance in the wrong patient. I do not believe in chasing a small, inconsistent tightening effect at the expense of the soft tissue volume and integrity that make a face look youthful in the first place.

I feel similarly about procedures where the risk profile is out of proportion to the aesthetic benefit. The Brazilian butt lift has become safer when performed with modern protocols, ultrasound guidance, and strict attention to injection plane, but it has historically carried one of the most serious mortality concerns in cosmetic surgery. I also would never endorse free silicone injections or other permanent injectable shortcuts, because the complications can be devastating, delayed, and extraordinarily difficult to correct. Permanent materials have a way of becoming permanent problems.

There are also procedures I avoid because they may burn bridges for future, better options. In my practice, I am careful with biostimulatory products in patients who may later want surgical facial rejuvenation. In theory, collagen stimulation sounds appealing. In reality, anything that changes tissue planes, creates unpredictable fibrosis, or obscures anatomy can make future surgery more difficult. Aesthetic medicine should not just solve today’s concern. It should preserve tomorrow’s possibilities.

My philosophy is not anti-technology, anti-injectable, or anti-innovation. It is anti-hype. The question is never only, “Can this be done?” The better question is, “Is this beautiful, safe, reversible when possible, anatomically respectful, and compatible with the patient’s future?” If the answer is no, I will not do it.
