How to Get Rid of a Double Chin Fast: What Really Works

A double chin is extra fat and loose skin under your jaw. It can show up even if you are not overweight.

Most articles online about how to get rid of a double chin tell you to do neck exercises. The truth is simpler and a bit different. Exercises alone will not remove the fat. Only a few things actually work, and we will walk through each one.

Here is the short answer:

Below, we explain why a double chin forms, what really works, and what is just a myth. No confusing medical terms. Just clear, honest answers.

What Is a Double Chin, Really?

A double chin is a layer of fat and skin that sits under your jaw. It can make your neck and chin look rounder from the side.

Doctors call this area the “submental” area. That just means “under the chin.” You do not need to remember that word. We only mention it once, in case you see it used elsewhere.

A double chin is not always about weight. This is the part most people get wrong.

• Some people who are slim still have a double chin.
• Some people who carry extra weight do not have one at all.
• It can come from your bone shape, your skin, your age, or your weight — often more than one of these at once.

So before trying to fix it, it helps to know what is actually causing yours. That is what we cover next.

What Causes a Double Chin (6 real causes)

A double chin usually comes from more than one cause at the same time. Here are the six real reasons it happens.

1. Genetics

Some families just store fat under the chin more easily. This runs in families the same way height or eye color does. If your parents had a double chin, you are more likely to get one too, even at a healthy weight.

2. Jaw Shape and Bone Structure

A smaller or more set-back jaw gives less support to the skin underneath it. The skin and fat have less bone to rest on, so they hang forward and look like a double chin. This has nothing to do with how much you weigh.

3. Age and Loose Skin

As you get older, your skin loses collagen. Collagen is what keeps skin firm and tight. Once it breaks down, skin under the chin starts to sag. This can happen even if you have not gained any weight.

4. Weight Gain

This is the cause most people already know. When you gain weight, fat can build up anywhere on the body, including under the chin. It is often one of the first places people notice it.

5. Posture (“Tech Neck”)

Looking down at your phone or laptop all day puts your neck in a bent position for hours. Over time, this weakens the muscles under your chin. It does not create new fat, but it makes any fat you already have look more noticeable.

6. Medical Conditions

In rare cases, a double chin that shows up suddenly can point to a health issue. This includes an underactive thyroid, PCOS, or Cushing’s syndrome. If your double chin appeared fast, feels hard, or came with other changes in your body, it is worth mentioning to a doctor.

Can Exercises Get Rid of a Double Chin?

Short answer: not really. Chin exercises will not burn the fat under your chin. This surprises most people, so let’s explain why.

Why You Cannot “Burn Fat” From One Spot

This idea is called “spot reduction.” It means picking one body part and trying to lose fat only from there. Studies have tested this for decades, on stomachs, arms, and chins. The result is almost always the same.

When your body burns fat, it pulls from fat stores all over your body. It does not pull extra fat just because you moved the muscle underneath it. So doing 100 chin exercises a day will not shrink the fat pad under your jaw.

What the Research Actually Found

A large review of exercise studies looked at this exact question. It found no proof that working one muscle group shrinks the fat sitting on top of it, no matter who did the exercise or how often.

Jaw-exercise devices have been tested too. In one 2024 study, people used a jaw-training tool for weeks. Their double chin did not change. Their jawline did not change. The skin under their chin did not tighten either.¹Facial Contouring Through Jaw Exercises: A Report of Two Cases Examining Efficacy and Consumer Expectations, PubMed Central.↓

So Why Do People Still Recommend Chin Exercises?

Exercises can tone the muscle under your chin. A toned muscle can make your profile look slightly firmer. But toning a muscle is very different from removing the fat sitting on top of it. This is the mix-up most exercise videos never explain.

Bottom line: chin exercises will not remove your double chin. They may help the area look a little firmer, but the fat stays unless you address the real cause.

5 Chin and Neck Exercises That May Help Tone the Area

These exercises will not melt fat. But they can tighten and tone the muscles under your chin and jaw. Over time, that may make your profile look a little firmer. Do these daily for the best chance of a small change.

1. Chin Tuck

Sit or stand up straight. Look forward. Slowly pull your chin straight back, like you are making a double chin on purpose. Hold for 3 seconds. Relax. Do 10 reps, twice a day.

2. Jaw Release

Tilt your head back slightly, so you are looking at the ceiling. Open and close your mouth slowly, like you are chewing. Do this 10 times. You should feel it under your jaw and chin.

3. Tongue Press

Press your tongue flat against the roof of your mouth. Hold it there while you tilt your chin up slightly. Hold for 5 seconds. Release. Repeat 10 times.

4. Neck Stretch

Tilt your head back and look up at the ceiling. Push your lower lip up and over your top lip, like you are pouting. You should feel a pull under your chin. Hold for 10 seconds. Repeat 5 times.

5. The “O” Shape

Tilt your head back slightly. Shape your mouth into a wide “O.” Hold for 10 seconds. Relax. Repeat 10 times. This works the muscles right under the jawline.

Do these for 4 to 6 weeks before expecting any visible change. Remember, these tone muscle. They do not remove fat. If fat is your main issue, pair these with the weight loss or medical options covered later in this article.

Does Face Yoga Work?

Face yoga is a set of facial exercises. People move their mouth, cheeks, and jaw in specific patterns, often for 20 to 30 minutes a day. It gets a lot of attention online, so let’s look at what it can and cannot do.

What It May Help With

One study had a group of women do facial exercises for 8 weeks. Afterward, people looking at their photos guessed their age as almost 3 years younger. Their cheeks also looked a bit fuller.

So face yoga may help your face look a little firmer and fresher. This comes from toning the muscles, not from losing fat.

What It Cannot Do

Face yoga cannot remove the fat sitting under your chin. No study has shown this. The study above was about overall face appearance, not double chin removal. If your double chin is mostly fat, face yoga alone will not fix it.

Should You Try It?

It is free, safe, and takes a few minutes a day. If you enjoy it, there is no harm in doing it. Just do not expect it to replace weight loss or a medical treatment if fat is your main cause.

Face yoga can make your face look a little fresher. It will not get rid of fat under your chin.

Weight Loss: The One Method With Real Results

If fat is the main reason for your double chin, losing weight is the only proven way to shrink it without medical treatment. This is the simplest fact in this whole article, and it is backed by real evidence.

Why Weight Loss Works Here

When you lose weight overall, your body pulls fat from stores all over the body. The fat under your chin is one of those stores. As your total body fat drops, the fat under your chin can drop too.

This is different from exercise alone. Exercise tones muscle. A calorie deficit, from eating less or moving more, is what actually shrinks fat stores.

How Fast Should You Lose Weight?

Slow and steady works best for your chin and your skin. Losing about 1 to 2 pounds a week gives your skin time to tighten as the fat underneath shrinks. Losing weight too fast can leave loose skin behind, which can make a double chin look worse, not better.

What If Weight Loss Does Not Work for You?

This is important. If your double chin comes from genetics, jaw shape, or loose skin, weight loss will not remove it. You could lose a lot of weight and still see the same double chin in the mirror. This is common, and it does not mean you are doing anything wrong.

If this sounds like you, skip ahead to the medical treatments section. That is where the real fix is.

Weight loss works only if fat is your main cause. If you are already at a healthy weight and still have a double chin, the cause is something else, and weight loss will not fix it.

“Lose a Double Chin in 5 Days” — Is That Really Possible?

No. There is no safe way to remove real fat from under your chin in 5 days. If you see a video claiming this, it is not telling you the full truth.

Why 5 Days Is Not Enough

Fat does not disappear overnight. Your body needs weeks of a calorie deficit to pull fat from stores like the one under your chin. Five days is simply not enough time for that process to show any real result.

What Can Actually Look Different in 5 Days

Some things can make your chin look slightly better in a short time, even though the fat has not changed:

• Less bloating: Cutting back on salt and sugar for a few days can reduce water retention under your skin, including your chin and face.
• Better posture: Standing and sitting taller instantly makes a double chin look smaller, even without losing any fat.
• More sleep: Poor sleep can cause puffiness in the face. A few good nights of sleep can reduce that puffiness.²Cues of Fatigue: Effects of Sleep Deprivation on Facial Appearance, https://doi.org/10.5665/sleep.2964↓
• Hydration: Drinking enough water can reduce the puffy look that comes from dehydration.

These changes are real, but they are not fat loss. They just reduce temporary puffiness and improve how you are standing. The fat under your chin stays the same.

If someone promises fat loss in 5 days, they are selling you a trick, not a fix. Real fat loss under the chin takes weeks, not days.

Natural Remedies People Try (and What They Actually Do)

Lots of “natural” double chin tips get passed around. Some genuinely help a little. Others do nothing at all. Here’s the honest breakdown of each one.

1. Drinking more water. This helps reduce puffiness, not fat. If you are dehydrated, your face can look more swollen than it really is. Drinking enough water each day can reduce that swelling, but it will not touch the fat underneath.
2. Cutting back on salt. Too much salt makes your body hold onto water. This can make your face and chin look puffier than usual. Eating less salty food can reduce that puffiness within a day or two. Again, this is water, not fat.
3. Green tea. Some people claim green tea “burns” chin fat. There is no real evidence for this. Green tea may give a very small boost to your metabolism, but it is far too small to target fat in one specific spot.
4. Chewing gum. This works the jaw muscles, similar to a chin exercise. It will not remove fat. It may tone the jaw muscle slightly over time, the same way the exercises in Section 5 do.
5. Firming creams and chin masks. These products claim to “tighten” the skin. Most of what they do is temporary. They may make skin feel firmer for a few hours, but they do not reduce fat or create any lasting change.
6. Better posture. This is one of the few natural tips that actually makes a visible difference. Standing and sitting with your head up, instead of looking down, instantly makes a double chin look smaller. It does not remove fat, but it changes how the area looks right away.

Out of all the natural tips, posture gives the biggest instant visual change. Water and salt tips reduce puffiness, not fat. Creams and gum do not remove fat at all.

When to See a Doctor

Most double chins are harmless. But a few signs mean it is time to get checked out.

See a doctor if you notice any of these:

• Your double chin appeared suddenly, over just a few days
• It feels hard or firm, not soft
• It is only on one side, not both
• It is painful or tender to the touch
• It comes with other changes, like weight gain, fatigue, or skin changes

These signs can point to a thyroid issue, swollen glands, or another condition that needs treatment. This is rare, but worth checking.

If none of this applies to you, your double chin is almost certainly just fat or skin. Completely normal and not a health risk.
