Summary: This page details various aesthetic treatments offered by Dr Nyla Medispa to address skin laxity resulting from the use of weight loss injections like Ozempic and Mounjaro. It explains how rapid weight reduction can deplete collagen and elastin, leading to sagging in the face and body. The text highlights non-surgical solutions, including dermal fillers, radiofrequency therapy, and ultrasound treatments designed to restore volume and firmness. Additionally, it provides guidance on distinguishing between residual body fat and loose skin while suggesting lifestyle adjustments to support skin health. Ultimately, the clinic positions its specialised procedures as a way to refine physical appearance after significant metabolic changes.

What Are Weight Loss Injections?

Weight loss injections belong to a class of medications known as GLP-1 agonists, which were originally developed to help individuals with type 2 diabetes regulate blood sugar levels. These medications also suppress appetite, which can contribute to weight loss, making diabetes management easier.

Over time, researchers noticed that GLP-1 agonists were highly effective in reducing hunger and supporting weight reduction, which led to studies exploring their potential as dedicated weight loss treatments.

The most popular weight loss injections are as follows:

Mounjaro: Mounjaro is the brand name for tirzepatide and is a drug which lowers blood sugar levels. It activates two receptors – GLP-1 and GIP – to increase the levels of hormones in the body which slows down how quickly food is digested.
Ozempic: Ozempic is an FDA-approved injectable medication that mimics the GLP-1 hormone, which plays a key role in blood sugar regulation and appetite control. It works by slowing digestion and enhancing feelings of fullness, helping to achieve weight loss for individuals struggling with excess weight or obesity.
Wegovy: Wegovy, containing Semaglutide, is another injectable medication designed specifically for weight loss. Like Ozempic, it helps regulate appetite and blood sugar levels. Clinical trials have demonstrated its effectiveness in supporting significant weight reduction when combined with a healthy lifestyle. Unlike Ozempic, Wegovy is approved for weight management in individuals regardless of whether they have type 2 diabetes.
Saxenda: Saxenda is an FDA-approved injection containing Liraglutide. Also known as skinny pen, it works similarly to Ozempic and Wegovy by helping patients control their appetite and reduce calorie intake, and is prescribed as part of a structured weight management plan for those with weight-related health conditions.

Preventing and Addressing Loose Skin After Weight Loss

Dealing with loose skin after weight loss can be a common concern, especially when using weight loss injections like Ozempic or Wegovy. These injections can cause saggy skin, often referred to as Ozempic face or Wegovy face, as rapid weight loss can damage collagen and elastin fibres, leading to loose skin. To help prevent this, it’s important to give your body time to naturally tighten up. A diet rich in vitamins A, C, and E can boost collagen and elastin production, while weightlifting and resistance training can help build muscle, filling in areas where skin may sag. Additionally, non-invasive treatments can improve skin tone, texture, and tighten loose skin by stimulating collagen production.

How to Treat Ozempic Body

The type of treatment needed will depend on where you have loose skin. For example, if you’re looking to tighten loose skin on the stomach, a common side effect of significant weight loss, the Exilis Elite treatment can help. This skin tightening treatment improves skin laxity and texture, strengthening the collagen network and supporting the tissues to tighten and tone. NuEra Tight is another treatment we offer which uses radio frequency technology to tighten loose or sagging skin, as well as reduce areas of excess fat or cellulite.

Morpheus8 can also be used to target specific areas of the face or body where loose skin is affecting your confidence. This non-invasive treatment requires minimal downtown and stimulates collagen to tighten and firm the skin and enhance the texture.

How to Treat Ozempic Face

Rapid weight loss can be especially noticeable in the face. The reduction of fat that once provided structure and volume can lead to facial hollowing, more pronounced wrinkles, and sagging jowls.

Dermal fillers, which contain hyaluronic acid, can help to restore plumpness in the face and lift it for a more youthful and refreshed appearance. Another highly effective treatment to improve skin firmness is Ultherapy which uses ultrasound and radio frequency to reach deeper levels of skin to stimulate collagen and elastin production. This helps to tighten areas of sagging and lift the face without the need for surgery.

For those looking to restore volume in strategic areas, our 8-point facelift uses a combination of dermal fillers and anti-wrinkle injections to lift and smooth the complexion. This procedure adds volume to the skin which helps to refresh the face and provide a more youthful look.

What’s the Difference Between Loose Skin vs Fat?

Loose skin and fat may appear similar, but they have distinct characteristics. Loose skin is the result of lost elasticity after significant weight loss, ageing, or pregnancy, causing it to hang or wrinkle. It lacks firmness and doesn’t respond to diet or exercise.

In contrast, fat is dense and firm to the touch, often creating a fuller or rounded appearance. Unlike loose skin, fat can be reduced through lifestyle changes, such as diet and exercise, or medical treatments. Understanding the difference helps determine the most effective treatment approach.
