Must-Read in 2026! Slimming Pen Risk Guide: Ozempic Face, Anesthesia Safety, and Key Reminders for Aesthetic Surgery

Entering 2026, weight-loss injections, also known as "slimming pens," such as GLP-1 drugs like Ozempic and Wegovy, remain a popular choice for many to control their weight and improve their metabolism. As more and more people use them, similar questions are frequently heard in clinics, such as: "I've lost weight, but why does my face look older?" and "Can I still have plastic surgery after getting slimming injections?"

Actually, the slimming pen doesn't just help with weight loss. Clinically, it has been found that it may be related to facial fat loss, also known as...Ozempic face (also known as thin old face or masculine face)This is related to the fact that the delayed gastric emptying mechanism may affect the safety of anesthesia during subsequent surgeries. If the weight loss process does not simultaneously assess changes in appearance and surgical risks, it may lead to facial sagging, a more haggard appearance, and even increase the uncertainty of surgery. This is one of the key points that medical professionals have recently emphasized when discussing the side effects of slimming pens and cosmetic surgery planning!

Will the Slimming Pen Make Your Face Look Older? What Exactly is an Ozempic Face?

"Ozempic face" is not a formal medical diagnosis, but rather a clinical and media term used to describe a phenomenon resulting from the use of a slimming pen.Rapid weight loss in a short period of time leads to loss of collagen in the face, resulting in a thin, aged, and haggard appearance.This change has been increasingly noticed in recent years among those using slimming pens (such as Ozempic, Wegovy, and other GLP-1 drugs), and is colloquially referred to as...A strong, healthy face or a thin, slender face。

Common effects of appearance include:

●Loss of collagen in the mid-face and cheekbones leads to a sunken appearance.

● Deepening nasolabial folds and tear troughs make her look tired and haggard.

● Sagging jawline, making facial contours less defined.

These changes aren't caused by the slimming pen directly "damaging" the face. Rather, it's because the rapid weight loss results in the loss of not only fat but also the fat layer and soft tissue that normally support the face. When the facial structure can't adapt to the weight change, it can easily lead to what's called a "skinny old face" or a "muscular, overweight face," making one look older.

In other words, the problem isn't with the slim pen itself, but with...Is the rate of weight loss exceeding the rate at which facial tissues can adjust?This is why, in 2026, doctors will specifically remind users of the Slimming Pen to pay attention to changes in appearance, rather than just focusing on the weight number.

▍Slimming Pen and Anesthesia Safety—Another Risk You Must Know Before Surgery!

As the number of people using the Slim Pen increases,Are you using the Slim Pen?By 2026, this had become an important question during surgical and anesthesia assessments. This was not superfluous, but because it was closely related to actual anesthesia safety.

One of the mechanisms of action of the Slim Pen isDelaying gastric emptyingIn other words, even if you have fasted before the surgery as required, there may still be food or liquid residue in your stomach. Under anesthesia, this may increase the risk of gastroesophageal reflux, choking, airway obstruction, aspiration pneumonia, and so on. Therefore, you must be aware that the slimming pen does not only affect weight or appearance, but may also affect the surgical procedure itself.

Clinical advice from Arsty Clinic Plastic Surgeons︰

• Stop using the Slimming Pen at least two weeks before surgery.This allows sufficient time for gastric emptying to recover, reducing anesthesia-related risks.

• It is recommended to wait three months after surgery before resuming use.This is to ensure that wound healing and nutrient absorption are in a stable state.

Such a discontinuation schedule is not a formality, but a necessary arrangement based on clinical experience to balance surgical safety, anesthetic risks, and postoperative recovery.

After using the Slimming Pen, how should I schedule my cosmetic procedures? The key is actually in the "order".

Many people are now using slimming pen to lose weight, but they are starting to discover another problem—they have lost weight, but their face has become sunken, their skin has become loose, and they look older. Can this side effect be improved? In clinical experience, cosmetic procedures and weight loss are no longer two separate things to be dealt with. Instead, they need to be planned as a whole and arranged in stages in order to make the results natural and lasting.

① Facelift, body sculpting, and liposuction: Wait until your weight stabilizes before undergoing these procedures.

Such as Face Lifts, body sculpting, or liposuction.It is recommended to start after your weight has stabilized.To avoid continued weight loss after the procedure, which could affect the lifting effect and the maintenance of the contours, doctors always ask whether the patient is currently using a slimming pen and how much weight they are losing before evaluating cosmetic surgeries such as facelifts or liposuction.

② Facial filler treatment: Improves a "thin and aged" appearance, not by blindly adding fillers.

One of the common side effects of the slimming pen is the so-called "Ozempic face," which is often manifested as mid-face hollowing, loss of cheekbones, and insufficient facial contour support. In this case, autologous fat grafting or other filler implant surgery may be considered, depending on the situation. The key is not how much fat is added.，Instead, it involves structural assessment and precise replacement.If you choose hyaluronic acid or fillers, be careful not to overdo it, as it will look unnatural and may even cause a puffy or smudged face.

③ Skin tightening and texture treatment: to prepare the skin for sagging after rapid weight loss.

After rapid weight loss, decreased skin elasticity is a common problem. In this case, skin tightening treatments such as ultrasound and radiofrequency can be used to help improve skin laxity and overall firmness, which can also enhance the effect of subsequent surgeries or fillers.

Doctors warn: The real key isn't "how much" to do.

Using a slimming pen doesn't preclude you from undergoing cosmetic procedures; the key is when to use it and how to combine it with other treatments.，A comprehensive assessment, taking into account weight loss goals, facial structure, and skin condition, is necessary to avoid the problem of losing weight too quickly but appearing older.

Weight loss should not come at the cost of looking older!

For those currently using or considering using the Slimming Pen, weight loss is not just about losing weight. How it will change one's appearance, whether it will affect the safety of subsequent surgeries, and how to maintain the weight loss results are all key points of discussion. Based on clinical experience, the Arsty Clinic team offers the following professional advice:

✔ Avoid excessive pursuit of rapid weight loss

Rapid weight loss can lead to facial fat loss and sagging skin, increasing the risk of an "Ozempic face" and potentially affecting the outcome of subsequent cosmetic surgeries.

✔ Ensure adequate protein and nutrient intake to maintain muscle and structural support.

During weight loss, special attention should be paid to protein intake, and appropriate resistance training should be combined to help maintain muscle mass and body support structure, so as to avoid losing weight but looking older.

✔ Before surgery or treatment, be sure to honestly disclose your experience using the Slimming Pen.

Whether it's a facelift, liposuction, body sculpting, or any other cosmetic procedure,Inform your doctor in full beforehand about your use of GLP-1 drugs.This is crucial for surgical scheduling, anesthesia safety, and postoperative recovery.

✔ Comprehensive assessment by experienced plastic surgeons and anesthesia team

Weight loss, cosmetic procedures, and surgical risks must be considered together. Ideally, an assessment should be conducted jointly by a plastic surgeon familiar with the effects of weight loss drugs and an experienced anesthesia team to ensure both safety and aesthetics.

"Slim" is no longer just about a number on the scale, but a holistic balance of health, safety, and appearance. Slimming pens can be effective weight loss tools, but only by combining them with the correct weight loss rhythm, discontinuation schedule, and cosmetic medical planning can the risks of aging the face and surgery be avoided.
