Supplements for Skin Tightening After Weight Loss

Losing a significant amount of weight is a major accomplishment that brings numerous health benefits. However, it can sometimes leave behind loose or sagging skin which can be a source of frustration and self-consciousness. Loose skin is an unwelcome sign of skin aging. It typically occurs due to decreased production and degradation of collagen and elastin in the skin, but it can also follow rapid weight loss and weight loss surgery. While medical procedures are an option for some, many people prefer to explore natural methods first. The cosmetics industry offers various solutions to combat the loss of skin elasticity.

The Science Behind Loose Skin

Our skin is a remarkable organ with the ability to stretch and contract. This flexibility is thanks to two key proteins in the dermis (the skin's middle layer): collagen and elastin. Collagen provides the skin with its structure and firmness, while elastin allows it to stretch and return to its original shape. When we gain weight, our skin expands to accommodate the increased body mass. If the skin remains stretched for an extended period, the collagen and elastin fibers can become damaged, losing some of their ability to retract. While loose skin can be a cosmetic concern, it can also cause physical discomfort, such as chafing and irritation.

What Causes Skin to Lose Elasticity After Weight Loss?

Several factors contribute to loose skin following weight loss:

• Length of time: In general, the longer someone has had overweight or obesity, the looser their skin will be after weight loss due to elastin and collagen loss.
• Amount of weight lost: Rapid loss of substantial body weight typically results in a greater amount of loose skin than more moderate weight loss.
• Age: Older skin has less collagen than younger skin and tends to be looser following weight loss.
• Genetics: Genes may affect how your skin responds to weight gain and loss.
• Sun exposure: Chronic sun exposure reduces skin’s collagen and elastin production, which may contribute to loose skin.
• Smoking: Smoking leads to a reduction in collagen production and damage to existing collagen, resulting in loose, sagging skin.

The Role of Vitamins and Nutrients

One of the best ways to incorporate a natural and sustainable strategy for loose skin is to include more vitamins into your skincare regimen and diet. Just like the other organs in your body, your skin’s health depends on your nutritional intake. If the body had a need for artificial flavoring and preservatives to be healthy, the standard American diet would be the world’s gold standard. Unfortunately, this is not the case, and many of us aren’t getting adequate levels of important vitamins and minerals. Those missing nutrients can contribute to a long list of skin problems: acne, dryness, puffiness, undereye bags, fine lines and more. Certain nutrients are important for the production of collagen and other components of healthy skin.

Vitamin C

Ascorbic acid, or vitamin C, is naturally found in the dermis and epidermis, protecting the skin from environmental damage, but its production declines due to aging, sun exposure, and pollutants. One of the benefits of vitamin C is improved skin elasticity. Studies have shown it increases the activity of fibroblasts (the cells that secrete collagen proteins) and regulates collagen synthesis, making the skin firmer and smoother. Vitamin C is needed for collagen synthesis and also helps protect skin from sun damage. Vibrant Skin Bar recommends taking 5 ml (1 teaspoon) daily. Hold the liquid in the mouth for 30 seconds and then swallow.

Vitamin E

Vitamin E is another potent antioxidant. Vitamin E promotes collagen production, prevents its breakdown, increases water retention, and protects the skin from oxidative stress. The Vibrant Skin Bar skin experts recommend Vitamin C+E Complex by SkinMedica for a boost of these two vitamins. Apply one pump after cleansing and toning the skin in the morning and evening.

Vitamin A

Vitamin A is the ultimate anti-aging ingredient. Skin experts refer to it as the most effective wrinkle-reducing nutrient. Studies indicate it helps regenerate skin cells, remove damaged elastic fibers, and stimulate the production of collagen and elastin. Retinol Complex 0.5 by SkinMedica works wonders to improve skin elasticity and resilience, making it tighter and smoother. Your dermatologist may also suggest vitamin A-based topicals, such as tretinoin (Refissa®, Renova® and Retin-A®), which have shown in scientific studies and extended practice to be effective.

Vitamin K

Vitamin K is a lesser-known cosmetic ingredient that, nevertheless, boasts various properties that may help reverse skin aging. Increase vitamin K intake through diet by eating more green leafy vegetables, such as kale, spinach, broccoli, Brussels sprouts, and cabbage.

Vitamin D

Studies show normal vitamin D levels play a role in preventing premature aging signs. Its active metabolites help protect the skin from major skin aging factors, such as UV radiation and environmental pollutants, decreasing inflammation and repairing the skin’s epidermal barrier. Vitamin D can be administered orally or topically. It is also synthesized in the skin during sun exposure. Vibrant Skin Bar recommends Vibrant D supplements as a quick way to restore normal vitamin D levels and enhance immune function, bone and arterial health, and skin rejuvenation.

B Vitamins

Several B vitamins indirectly stimulate collagen synthesis, potentially helping tighten loose skin.

• Vitamin B3: Reduces inflammation, improves moisture retention, and strengthens skin barrier function. Good food sources of niacin include red meat, fish, poultry, legumes, and bananas.
• Vitamin B5: A humectant, it attracts and retains water, maintaining the skin’s firmness. It is found in chicken, beef, liver, kidney, and fortified cereals. When used in topical products, it is typically called panthenol or dexpanthenol.
• Vitamin B9: Assists in building new skin cells, helping skin regeneration. It is added to food and supplements in the form of folic acid. It is naturally found in dark green leafy vegetables, beans, peanuts, and many fruits.
• Vitamin B12: Maintains natural skin moisture and promotes healthy skin cell growth. It is present in many foods, including meat, fish, liver, eggs, and dairy products. The form of B12 most commonly used in topical skincare products is called cyanocobalamin.

Many people take B vitamin supplements for better absorption and quicker results. Vibrant B supplements provide the necessary daily intake of B vitamins to support metabolism and healthy skin. Take one capsule daily.

Coenzyme Q10

Coenzyme Q10 is an essential nutrient structurally similar to vitamin K and sometimes referred to as vitamin Q10. It has potent antioxidant properties and plays an important role in converting food into energy.

Omega-3 Fatty Acids

The omega-3 fatty acids found in fatty fish and plant sources, including walnuts, chia, and flax, may help increase skin elasticity and have anti-aging effects. Omega-3s are essential to keeping skin healthy, boosting hydration while stimulating the growth of new cells. The supplement’s 75% concentration of EPA+DHA is much higher than most commonly available fish oils, which means it can more quickly deliver its health benefits. EPA and DHA each have unique characteristics that benefit the optimization of health. EPA supports skin and brain health, balanced emotions and normal cholesterol levels.

Protein

Adequate protein is vital for healthy skin. The amino acids proline, hydroxyproline, and glycine play a direct role in collagen production.

Collagen Supplements

Collagen supplements have gained popularity for their potential skin benefits. Collagen hydrolysate is very similar to gelatin. It’s a processed form of the collagen found in the connective tissue of animals. Collagen hydrolysate, a form of collagen that has been broken down into smaller, more easily absorbed particles, has been the subject of several studies. Although it hasn’t been tested in people with loose skin related to major weight loss, an older study suggests that collagen hydrolysate may have a protective effect on skin’s collagen.

A 2019 controlled study demonstrated that a liquid collagen supplement significantly improved skin elasticity, texture, and hydration after 12 weeks of use. It comes in powdered form and can be purchased at natural food stores or online. Whole Body Collagen contains a unique blend of three collagen peptides backed by clinical research that shows their efficacy for supporting collagen production, skin elasticity, joint health, and more. Another popular source of collagen is bone broth, which can also provide other health benefits.

MSM (Methylsulfonylmethane)

MSM supports healthy hair, skin and nails. As we age, our skin often dries out because we lose some of our natural oils and experience a decrease in cell renewal.

Other Natural Strategies

Dealing with loose skin after weight loss can be challenging, but there are natural, evidence-based strategies that can help.

Resistance Training

One of the most effective ways to improve the appearance of loose skin is to fill the space with muscle. Engaging in regular strength training is one of the most effective ways to build muscle mass in both young and older adults. The Physical Activity Guidelines for Americans recommends doing strength training twice a week. Resistance training, also known as strength training, helps build lean muscle mass, which can create a firmer, more toned look. While research isn’t currently available, it’s possible that an increase in muscle mass may help improve the appearance of loose skin.

A groundbreaking 2023 study published in Scientific Reports found that resistance training can rejuvenate aging skin by improving skin elasticity and increasing dermal thickness [4]. This research suggests that the benefits of resistance training go beyond just building muscle; it can have a direct, positive impact on the skin itself.

Hydration

Water is essential for maintaining skin health and elasticity. Staying well-hydrated may improve the skin’s appearance. An older 2015 study found that women who increased their daily water intake had significant improvements in skin hydration and function. Drinking plenty of water helps keep your skin plump and elastic.

Massage

Massage may improve blood flow and stimulate fibroblasts. Fibroblasts are cells that help produce connective tissues, such as collagen and elastin, that keep skin firm. A small study in 2025 asked women ages 20 to 50 to use either a facial roller or gua sha facial massage for 10 minutes, 5 times per week for 8 weeks. Both groups showed improved facial contours but through different mechanisms. The facial roller group achieved this through increased skin elasticity and the gua sha group’s results were due to changes in muscle tone. Another small study found that performing a 3-minute massage routine every day for 2 weeks lead to improvements in skin plumpness, fine lines, and radiance. Massaging the skin, especially with essential oils, can help improve blood circulation and promote skin tightening.

Topical Treatments

A high-quality skin tightening cream can help improve elasticity and firmness. Regular exfoliation helps remove dead skin cells and stimulates blood circulation, promoting skin renewal and firmness. Many different firming gels, creams, patches, and other products are available for the topical treatment of minor cases of loose skin. People who wish to purchase a firming product should look for products containing retinoid compounds. Retinoids are potent antioxidants that may boost collagen production.

However, experts do not consider firming products to be effective overall, and their penetration of the skin may not be deep enough to help lift sagging skin. According to the American Academy of Dermatology, most firming products offer subtle results at best, mostly by acting as a moisturizer. People who do observe results with these products may need to keep using them to continue seeing results.

Lifestyle Adjustments

Tightening loose skin after weight loss requires a holistic approach-a combination of proper nutrition, exercise, skincare, and supplements can help you achieve firmer skin over time. Sleep is essential for skin repair. Smoking breaks down collagen and elastin, making the skin sag faster. If we want to slow down the loss of collagen, it’s best to know and avoid environmental hazards. Specifically, stay away from cigarettes and other harmful toxins, consistently apply sunscreen and wear hats and other protective clothing when outdoors. It’s also helpful to use topical antioxidants (like vitamins C and E) to protect against external aggressors like smoke and UV rays. Lastly, it’s very important to stay well-hydrated.

Medical and Surgical Treatments

Can medical treatments tighten loose skin from weight loss? Medical or surgical treatments are more invasive options to tighten loose skin after major weight loss.

Body Contouring Surgery

People who have lost a significant amount of weight via bariatric surgery or other weight-loss methods often request surgery to remove excess skin. In body contouring surgery, a surgeon makes a large incision and removes excess skin and fat. They then suture the incision with fine stitches to help minimize scarring. Specific body contouring surgeries include:

• Abdominoplasty (tummy tuck): Removal of skin from the abdomen.
• Lower-body lift: Removal of skin from the belly, buttocks, hips, and thighs.
• Upper-body lift: Removal of skin from the breasts and back.
• Medial thigh lift: Removal of skin from the inner and outer thighs.
• Brachioplasty (arm lift): Removal of skin from the upper arms.

Multiple surgeries are usually performed on different body parts over time after major weight loss. Body contouring surgeries may require a brief hospital stay, followed by a period of recovery time at home. There may be also some complications from the surgery, such as bleeding and infections. Several studies have found that body contouring surgery may improve quality of life after significant weight loss.

Alternative Medical Procedures

Although body-contouring surgery is by far the most common procedure to remove loose skin, less invasive options with a lower risk of complications include:

• Radiofrequency treatment: Such treatments may use a combination of infrared light, radiofrequency, and massage to reduce loose skin. While this treatment doesn’t induce weight loss, it may help reduce small areas of fat cells.
• Ultrasound: A 2019 research review of ultrasound treatment for skin tightening found it to be efficacious, effective, and safe with minimal adverse effects. A high intensity focused ultrasound (HIFU) facial works on the deepest layers of the skin. Most people notice subtle lifting and tightening within 2 to 6 months of their first treatment and report more significant results with additional treatments. The effects of the treatment can last for up to 1 year.
• Laser treatments: Laser treatments focus on the outer layer of the skin, which is called the epidermis. Most people need between three and five treatments to see results, and changes are usually visible 2 to 6 months after the last treatment. Laser treatments are especially useful on the upper arms and belly. Laser skin resurfacing is the most effective nonsurgical procedure for tightening loose skin. It can also reduce wrinkles, fine linkes, and age spots. Most people require 5 to 7 days of rest after the procedure and typically notice results 2 weeks after they heal. Laser resurfacing carries a small risk of scarring.
• Nonsurgical radiofrequency: In the nonsurgical form of radiofrequency, a dermatologist will place a device against the skin to heat the tissue underneath. Most people who use this method see results after one treatment. The treatment takes about 6 months to take full effect, but some people notice tightening shortly after the procedure. With the right skin care, the results may last for 2 to 3 years.
• Surgical radiofrequency: The minimally invasive form of radiofrequency involves inserting tiny tubes through small incisions in the skin to send heat to the areas that require tightening. Doctors often perform this procedure on the neck or upper arms, and it may produce results within 1 month. This procedure usually takes place under local anesthesia, and most people need to wear compression bandages for 4-5 days afterward.
• Intense pulsed light (IPL): People often undergo treatment with intense pulsed light (IPL) in combination with radiofrequency to more effectively treat the skin at different levels. A person may require a series of IPL treatments to see results, and it is sometimes unsuitable for those with darker skin tones or tanned skin.

It appears that although there are fewer risks with these alternative procedures, the results may not be as dramatic as with body contouring surgery.

Potential Problems Caused by Excess Loose Skin

For some people, loose skin from a lot of weight loss may cause physical and emotional challenges:

• Physical discomfort: Excess skin may be uncomfortable and possibly interfere with normal activity.
• Emotional discomfort: An older longitudinal study found a possible increase in self-consciousness after weight loss.
• Decreased physical activity: While a 2022 study found that weight loss encouraged more people to exercise, excess skin was found to interfere with exercise in some people after bariatric surgery.
• Skin irritation and breakdown: An older 2014 study found that of 124 people who requested plastic surgery to tighten skin after weight loss surgery, 44% had reported skin pain, ulcers, or infections due to the loose skin.
• Body dissatisfaction: Loose skin from weight loss may negatively affect body image and mood.

The Truth About Collagen Supplements

Collagen supplements aren’t the best option if you want to improve the appearance of your skin. That’s mainly because there’s no evidence-based science to prove they work - or that they’re safe. A few small studies have shown limited improvement in skin texture with collagen supplements,” notes Dr. Khetarpal. “But it’s important to point out that they’re all manufacturer-sponsored studies. And unfortunately, the supplement industry isn’t well regulated and has a history of inaccurate labeling and contamination.”

Dr. Khetarpal says that collagen supplements are mostly absorbed by your GI tract, which means that there isn’t enough collagen that makes it into your bloodstream to be delivered to your hair, nails and skin. Another factor? Most supplements are made with animal collagen and it’s unclear whether this form of collagen is close enough to human collagen to be beneficial.

Fans of collagen supplements claim that they may:

• Hydrate skin
• Improve elasticity
• Improves hair and nail growth
• Strengthen bones and muscles
• Ease joint pain

But remember: Research doesn’t necessarily back up the benefits of collagen supplements. It can take three to six months of use before you may begin to see results.

The processed form of collagen, which may be called collagen peptides, comes from animal tissue discarded by meat processors. This substance is ground into a gelatin or powder and placed in a capsule or gummy tablet, along with other sometimes-unnamed byproducts. With the increasing number of food allergies today, this is a critical consideration.

Overall, the side effects of collagen supplements are minimal. You may experience the following:

• Headache
• Lightheadedness
• Diarrhea

A daily dose may be anywhere from 2.5 to 15 grams. You may want to also consider the cost of collagen supplements - especially if you take them daily. It can be a costly endeavor that may not add up to any meaningful results.
