Significant weight loss can bring about many positive changes in one's health and overall well-being. However, it can also lead to unexpected changes in the face, such as the appearance of wrinkles and sagging skin. This article explores the causes of these facial changes and discusses various treatment options to restore a more youthful appearance.
Understanding Weight Loss and Skin Changes
The Impact of Rapid Weight Loss
Rapid weight loss, often defined as losing 35 or more pounds in six months or less, can significantly impact the skin's health and appearance. According to Michele Koo, MD, a plastic surgeon, such rapid weight loss can deplete the skin and body of essential nutrients, disrupting the body's homeostasis. This disruption can lead to:
- Thinning of the skin
- Loss of elasticity and luster
- Disruption of collagen and elastin metabolism
- Sallow, dull, and thin skin
- Loss of volume in the cheeks
The Role of Fat Loss
Fat plays a crucial role in maintaining the skin's elasticity and firmness. When weight loss occurs, fat is reabsorbed and atrophies, contributing to an aged and gaunt look. Shafer illustrates this concept with the analogy of a balloon: as air is released, the balloon becomes loose, and its elasticity cannot compensate for the loss of volume. Similarly, with weight fluctuations, the skin stretches and recoils, but its capacity to contract decreases with age and weight loss, leading to skin laxity.
The Influence of Age
As we age, our skin naturally produces less collagen, a protein that keeps the skin firm and elastic. This decline in collagen production, combined with weight loss, can exacerbate sagging skin. The older you are, the less elastic ability your skin has to bounce back.
Causes of Facial Changes After Weight Loss
Several factors contribute to facial changes after weight loss, including:

- Age: As we age, we produce less collagen, leading to decreased skin elasticity.
- Amount of weight lost: Losing a significant amount of weight can cause the skin to stretch and sag.
- Speed of weight loss: Rapid weight loss doesn't give the body enough time to readjust, leading to loose skin.
Prevention Strategies
While it may not be possible to completely prevent facial changes after weight loss, there are several strategies to minimize their impact:
Gradual Weight Loss
Aim for a slower, more gradual weight loss of about one to two pounds per week. This allows the skin more time to adjust to the changing body composition.
Healthy Diet and Hydration
Eat a well-balanced diet rich in fruits, vegetables, and lean protein to nourish the skin and support collagen production. Staying hydrated is also crucial for maintaining skin elasticity.
Skincare Routine
Establish a consistent skincare routine that includes cleansing, moisturizing, and sun protection. Look for products with ingredients like retinol, niacinamide, and vitamin C, which can help reduce fine lines and wrinkles.
Facial Exercises and Massage
Regular facial exercises and massage can help improve muscle tone and circulation, potentially improving the appearance of the skin.

Treatment Options
If you're dissatisfied with the way your skin looks after weight loss, a variety of treatments are available, ranging from over-the-counter products to professional procedures.
Over-the-Counter Products
- Supplements: Certain supplements, such as collagen, hyaluronic acid, and vitamins A, C, D, and E, may help improve skin elasticity.
- Skin-tightening creams: Look for creams with ingredients that stimulate collagen and elastin production.
In-Office Treatments
Dermal Fillers: Injectable fillers like Juvéderm and Restylane can restore lost volume in the cheeks, temples, and around the mouth. These fillers, particularly hyaluronic acid fillers, are a popular choice for adding volume to specific areas and can provide natural-looking results when injected by experienced professionals. Restylane Contour and Restylane Lift are FDA-approved hyaluronic acid fillers for the midface and cheeks, respectively. Results typically last between six months and two years, with maintenance treatments recommended to sustain the effect.
Calcium Hydroxylapatite (Radiesse) and Poly-L-Lactic Acid (Sculptra): These fillers stimulate natural collagen production. Radiesse adds volume and stimulates collagen, while Sculptra requires multiple sessions and is better for generalized filling.
Lasers and Energy-Based Devices:
- Genius Radiofrequency Microneedling: This newer technology uses small needles to pierce the skin and send energy below the surface, stimulating collagen and tightening the skin.
- Fractionated CO2 Resurfacing: CO2 lasers are effective for skin tightening and can improve fine lines and pigmentation.
- Ulthera or Sofwave (Microfocused Ultrasound): These treatments use ultrasound energy to stimulate collagen formation below the skin's surface.
Other Skin Treatments:

- Renuvion: This treatment uses helium plasma energy to tighten skin, particularly in the neck area.
- Fat Transfer: Fat is removed from other areas of the body and injected into the face to restore volume.
Surgical Options
- Face Lift or Neck Lift: These surgical procedures tighten the underlying muscle, reposition fat, and tighten the skin.
Specific Treatment Options in Detail
Dermal Fillers: Juvéderm and Restylane
Dermal fillers are a popular and effective solution for addressing volume loss in the face due to weight loss. Among the various options available, hyaluronic acid fillers like Juvéderm and Restylane stand out as particularly favored choices. These fillers work by adding volume to specific areas of the face, such as the cheeks, temples, and around the mouth, helping to restore a more youthful and refreshed appearance.
The Food and Drug Administration (FDA) has approved several hyaluronic acid fillers for use in specific areas of the face. For instance, Volux is the only FDA-approved hyaluronic acid filler designed for the jawline, while Restylane Contour and Restylane Lift have received FDA approval for use in the midface and cheeks. These approvals underscore the safety and efficacy of these fillers when used by qualified and experienced injectors.
When administered by skilled professionals, dermal fillers can provide natural-looking results that enhance facial contours and reduce the appearance of sagging or hollowing. While not permanent, the effects of these fillers typically last between six months and two years. However, it's important to note that the duration of the full effect may vary, and maintenance treatments are often recommended to sustain the desired outcome.
To maintain optimal results, Shafer suggests "topping up" the filler after one year, even if the filler is said to last for two years. This involves injecting a smaller amount of filler to refresh the initial treatment and prolong its effects. The amount of filler needed for maintenance will depend on individual factors, such as metabolism and the desired level of correction.
The cost of hyaluronic acid fillers like Juvéderm and Restylane can vary, with an average cost of $684 per syringe, according to the American Society of Plastic Surgeons. However, it's crucial to prioritize quality and expertise over price when choosing a provider for dermal filler injections. Selecting a board-certified provider with a proven track record can help ensure a safe and satisfactory outcome.
Calcium Hydroxylapatite (Radiesse) and Poly-L-Lactic Acid (Sculptra)
In addition to hyaluronic acid fillers, other dermal fillers like Calcium Hydroxylapatite (Radiesse) and Poly-L-Lactic Acid (Sculptra) offer alternative approaches to facial rejuvenation. These fillers differ from Juvéderm and Restylane in their composition and mechanism of action.
Radiesse contains gel microspheres that not only add volume but also stimulate the body's natural collagen production. This dual-action effect can provide both immediate and long-term benefits, helping to restore facial contours and improve skin quality over time. Dermatologists often use Radiesse for pinpoint injections and definition, similar to hyaluronic acid fillers. The effects of Radiesse typically last for one to two years.
Sculptra, on the other hand, works primarily by stimulating natural collagen production under the skin. This filler requires multiple treatment sessions to achieve the desired results, but the effects can last for two to three years once the goals are met. Sculptra is particularly well-suited for generalized filling, addressing overall volume loss rather than targeting specific areas.
The cost of Radiesse and Sculptra treatments will vary depending on the amount of filler used and the number of sessions required to achieve the desired outcome. Saedi notes that patients typically need multiple syringes per visit, with costs averaging around $1,000 per syringe.
Lasers and Energy-Based Devices: Genius Radiofrequency Microneedling
Radiofrequency microneedling is an innovative energy technology that has gained popularity in recent years for its ability to rejuvenate the skin and address concerns like wrinkles and sagging. One such device, Genius, received FDA approval in 2019 for treating both the face and body.
The procedure involves using small needles to create micro-injuries in the skin while simultaneously delivering radiofrequency energy to the deeper layers. This combination stimulates collagen production and tightens the skin from within. According to Shafer, the microneedles penetrate deeper than lasers can, allowing for more effective treatment of underlying tissues.
While a single treatment may be sufficient for some individuals, others may require two to three sessions to achieve optimal results. Prices for Genius radiofrequency microneedling typically start at $3,500 but can vary depending on the treatment area and whether discounts are offered as part of a package.
Fractionated CO2 Resurfacing
Fractionated CO2 lasers have long been considered a mainstay in skin tightening, with over 100 FDA-cleared uses across various medical specialties. Approved by the FDA in 2004, these lasers work by treating the superficial layers of the skin, resulting in substantial improvements in fine lines and pigmentation.
While the downtime associated with fractionated CO2 resurfacing can be up to two weeks, the results can be significant. Prices typically start at $3,500 and vary depending on the treatment area and the degree of skin laxity. Most individuals require only one treatment per year to maintain the benefits.
Shafer emphasizes the importance of combining treatment modalities to achieve better results than with a single treatment type. However, he also cautions that energy-based skin tightening treatments like CO2 lasers are not equivalent to surgical skin tightening and cannot achieve the same degree of tightening as surgical excision.
Ulthera or Sofwave (Microfocused Ultrasound)
Microfocused ultrasound treatments like Ulthera and Sofwave offer non-invasive options for lifting and tightening the skin. Ulthera received FDA approval in 2014 for lifting the eyebrow, chin, and neck area, as well as improving lines and wrinkles in the low neckline or décolleté. Sofwave, cleared by the FDA since 2020, is indicated for improving fine lines and wrinkles on the face and neck, and has since received approval for treating skin laxity on the upper arm.
These treatments utilize ultrasound energy to stimulate collagen formation below the skin's surface. The results of microfocused ultrasound treatments become more apparent over time, typically over two to three months, as the body produces new collagen.
The procedure takes approximately 30 to 90 minutes, depending on the area being treated, and there is no downtime afterward. Treatments start at $2,000 but vary by body area. While most patients only need one treatment, some may benefit from additional sessions depending on the extent of skin laxity and their body's response to the treatment. Follow-up treatments each year may help maintain results.
Other Skin Treatments After Weight Loss: Renuvion
Renuvion is a treatment that uses helium plasma energy to tighten skin, particularly in the neck area. Approved by the FDA in 2022, this one-time treatment is performed under the skin through tiny incisions under local anesthesia. The recovery time is moderate, ranging from one to three weeks.
When applied under the skin during a liposuction procedure, Renuvion helps enhance skin tightening in the neck and throughout the body. When applied externally, the plasma energy stimulates skin tightening. The average cost of Renuvion is around $6,000.
The FDA has also approved a separate device, the Renuvion Dermal Handpiece, for treating moderate to severe wrinkles and rhytides in patients with Fitzpatrick Skin Types 1, 2, or 3.
Fat Transfer
Fat transfer is another option for plumping up the face after rapid weight loss. This procedure involves removing fat from the hips or abdomen, cleaning it, and reinjecting it into areas of the face that have lost volume, such as the cheeks, under the eyes, around the lips, and in or around the chin, mouth, or temple areas.
Plastic surgeons can place fat anywhere there is a deficit. However, certain areas, such as under the eyes, require tiny amounts spread out over the entire area due to the risk of fat embolism and awkward distortion.
Fat injections for the face are best done a few cell layers at a time, as a thin layer increases the likelihood of cell survival. Therefore, depending on how many areas and which areas are treated, along with how much fat the surgeon is transferring, several sessions may be necessary. Transferring fat a little at a time ensures a slower, more gradual change in volume instead of a one-time large expansion, which can distort and drastically change facial shape in a very short time.
The goal is to achieve a soft-plumped version of yourself, not a blown-up one. Prices vary by region, but you can expect to pay $2,500 to $10,000 per treatment, depending on the volume of the injection. Delicate areas around the eyes or nose take more time, finesse, and care due to higher risks, so expect to pay more.
Face Lift or Neck Lift
For individuals in their late fifties and sixties, filler may not be enough to address volume loss and sagging skin. In these cases, plastic surgery, such as a facelift or neck lift, may be necessary.
During these surgical procedures, surgeons tighten the underlying muscle, reposition and sometimes augment the underlying fat, and then tighten the skin. Patients are often pleasantly surprised at the recovery and dramatic but natural-appearing results.
Prices can vary from $25,000 to more than $100,000, depending on the extent of the procedure and who is performing it. The location of the treatment can also affect pricing.
The Psychological Impact
It's important to acknowledge the psychological impact of facial changes after weight loss. While weight loss can improve overall health and self-confidence, changes in facial appearance can sometimes lead to dissatisfaction and self-consciousness.
