“In general, it can take anywhere from weeks to months—even years,” says Dr. Chen. If after one to two years skin is still loose, it may not get any tighter, she says.
For small to moderate amounts of weight loss, your skin will likely retract on its own. Natural home remedies may help too. However, more significant weight loss may need body-contouring surgery or other medical procedures to tighten or get rid of loose skin.
However, larger amounts of weight loss, such as 50 pounds and over, especially over a short period, can considerably increase your risk of loose skin. Your genetics and age will also play an important role in determining how much weight loss causes loose skin.
Collagen production starts to decline around 25 years of age, decreasing approximately 1-2% per year afterwards. Skin noticeably starts to lose its elasticity in your 30s to 40s and particularly in the first five years of menopause when women's skin loses around 30% of its collagen.
The longer you have been obese or overweight, the looser your skin will be after losing weight. Depending on the quality of your skin and other risk factors, losing 100 pounds or more can result in more loose skin.
When you lose a lot of weight, such as 100 pounds or more, your skin may not be elastic enough to shrink back to its natural shape. This can cause the skin to sag and hang, especially around the upper face, arms, stomach, breasts, and buttocks. Some people don't like the way this skin looks.
For some patients, even though they lose hundreds of pounds, their skin bounces back quite successfully. Unfortunately, this is quite rare. What often happens is that patients are left with excess, sagging skin after significant weight loss.
Of course, you can't reverse the signs of aging completely. You can go the nonsurgical route and add firming creams or facial exercises to your skincare routine. There are also cosmetic procedures that provide quicker results, such as laser surfacing or ultrasound skin tightening.
The loose skin is caused by losing a huge amount of weight – as in, 100 pounds or more – in a very short amount of time. It can happen when the weight is lost through diet and exercise, but it happens more often to weight-loss surgery patients.
Engaging in exercise such as resistance training can increase muscle mass. Building muscle through exercise can improve the appearance of sagging skin, especially in the legs and arms. Also, facial exercises may improve muscle tone around the jaw and neck. This may reduce sagging skin in these areas.
If you drop large amounts of weight, especially from quick reductions in belly fat, it is possible you will have some extra skin left behind. Prolonged periods of obesity can stretch your skin, eventually damaging the collagen and elastin that help keep your skin tight.
On the other hand, some have lost as little as 60 pounds and have more. “The magnitude of weight loss doesn't predict how much excess skin you may have,” he says. Other factors, like genetics, smoking (which degrades collagen and elastin), and sun exposure also play a role in your skin's springiness.
“Your skin may not contract back to its smaller shape if weight is lost too quickly.” This inability for the skin to contract as well as it once would have, due to the weakening of the fibers over time, is what leads to excess or saggy skin during weight loss.
“In general, it can take anywhere from weeks to months—even years,” says Dr. Chen. If after one to two years skin is still loose, it may not get any tighter, she says.
Excess skin can appear when you lose between 40 and 50 pounds. A dramatic weight loss of 100 plus pounds will almost certainly result in loose skin. If you drop 20 pounds or less, your skin will not produce excess, much less get so loose as to hang off your torso and limbs.
Loss of skin elasticity is known as elastosis. Elastosis causes skin to look saggy, crinkled, or leathery. Areas of the skin exposed to the sun can get solar elastosis. These parts of the body may look more weathered than those protected from sun exposure.
According to the doctors on the show, your 40s is when you really start to see major changes in the firmness of your skin. You're dealing with loss of volume and elasticity (leading to skin that appears saggy), as well as more pronounced wrinkles and sun damage, which may lead to conditions like melasma.
Collagen is a protein that serves as one of the main building blocks for your bones, skin, hair, muscles, tendons, and ligaments. "Collagen is what keeps our skin from sagging, giving us that plump, youthful look," says dermatologist Dr. Ohara Aivaz.
Exercise cannot cause muscles to pull skin tighter or shrink it back to size. However, as your muscles grow and develop, they can fill the excess skin left from weight loss, stretching and smoothing the outermost layers of skin for a more even, youthful and healthy look.
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.
However, new collagen growth can take anywhere from four to 12 weeks to complete. Keep in mind that while certain procedures can be very effective at restoring and replacing collagen, these results aren't permanent. Depending on the collagen rebuilding procedure and areas treated, results can last a year or longer.
A good moisturizer can plump up your skin, making fine lines and wrinkles less noticeable. This result is temporary. To continue seeing any benefit, you need to apply the product every day. As for the claim that a cream or lotion can lift sagging skin, dermatologists say that's not possible.
How Much Weight Can I Lose in 3 Months? A safe, healthy, and realistic goal is to lose 0.5-to-1% of your body weight per week, which is around 1-to-2 pounds of weight loss per week for most people. In other words, you can expect to lose 12-to-24 pounds in a 3-month period.
