These two get bundled together constantly, usually under a title promising a slimmer face. They’re different problems with different causes, and only some of what causes them responds to anything you can do with your own muscles.
Working out which you have takes about a minute, and it decides whether the next twenty weeks are worth spending.
What jowls actually are
Jowls are the softness that appears along the jaw, just in front of where the jaw turns up toward the ear. They come from several things happening together.
The ligaments that hold the cheek tissue in place loosen with time. The mid-face loses volume, so tissue that used to sit high on the cheek settles lower. Skin gives, because collagen and elastin change. And the muscle underneath weakens, which is the only part of that list exercise touches.
That last point matters more than most content on this admits. Face yoga for jowls works on one layer of a problem that has four. It isn’t nothing, and it also isn’t the whole thing.
What a double chin is made of
Four possibilities, and they respond very differently.
Fat under the chin. The submental fat pad. Common, often genetic, and entirely unrelated to overall weight in some people. Exercise does not reduce it, because spot reduction of fat is not a thing the body does.
A slack platysma. The platysma is a broad thin sheet of muscle running from the collarbone up over the jaw. When it loses tone, the line between chin and neck softens. This one does respond.
Head position. A head carried forward, over a phone or a desk, shortens the front of the neck and creates a fold that looks exactly like a double chin. Correct the posture and it changes within seconds.
The jaw itself. A jaw set slightly back gives less shelf for the tissue underneath to sit on. That’s skeletal, and nothing on this page changes it.
The quick sort
Tip your head back and hold a light contraction through the front of the neck.
If the area firms up noticeably, there’s muscle tone to work with, and exercise has something to act on. If it stays soft no matter what you do, you’re most likely looking at fat, and the honest answer is that face yoga for a double chin won’t shift it.
Then check your profile in a mirror, first slouched and then with your head drawn back over your shoulders. If most of the fold disappears in the second position, the problem is largely postural — and that’s the version with the fastest fix on this page.
The part almost nobody mentions
Posture does more for the jaw and neck line than any exercise here, and it does it immediately.
A forward head position shortens everything down the front of the neck and slackens the platysma. Hours of that daily works against every minute you spend on exercises. Fixing how you sit won’t build muscle, but it changes what the profile looks like the moment you do it, and it stops the slow drift that the exercises are trying to counter.
This is unglamorous, which is presumably why it rarely appears in content promising a slim face in two weeks.
Five exercises for these two specifically
Different from a general jawline routine: these target the mid-face lift and the neck line rather than the jaw joint.
1. Chin tuck. Sit tall. Draw your head straight back over your shoulders, as though making a double chin on purpose. Hold five seconds, ten times. This works the deep neck flexors that hold your head in place, and it’s the one that pays back fastest.
2. Cheek lift against resistance. Place two fingers flat on the top of each cheekbone, pressing gently down. Smile upward against that pressure. Hold ten seconds, five rounds. The fingers stop the skin from sliding, which is the point: pulling at skin is how people make laxity worse.
3. Platysma flex. Pull the corners of your mouth down and back, hard enough that the cords in your neck stand out. Hold five seconds, ten times. It looks unpleasant and works the exact muscle that softens the chin-to-neck line.
4. Tongue slide. Press the tip of your tongue behind your upper front teeth, then slide it back along the roof of your mouth as far as it goes. Hold three seconds at the back. Ten times. This works the floor of the mouth, the layer directly under a soft chin.
5. Corner lift. Place a fingertip at each corner of your mouth without pressing. Lift the corners into a small smile, hold ten seconds, five rounds. The zygomaticus muscles lift the mid-face, and the mid-face is what falls to make jowls.
Ten minutes, and the first one can be done anywhere without looking strange.
How long, realistically
The study behind facial exercise ran twenty weeks — daily for eight, then every other day for twelve. That’s the timeline the evidence describes, and there’s no shorter version of it.
Posture is the exception. That changes the profile the moment you correct it, which makes it the only thing here with an immediate payoff.
What it doesn’t do
It doesn’t remove submental fat. Working the muscle under a fat pad doesn’t reduce the pad. If that’s what you have, this is the wrong tool.
It doesn’t tighten loose skin. Laxity is a change within the skin. A stronger muscle underneath doesn’t restore it.
It doesn’t lift a loosened ligament. The structures anchoring the cheek aren’t muscle and don’t strengthen with use.
It can widen the lower face. Heavy jaw work builds the masseter. In someone who already clenches, that makes the jaw look broader, not slimmer — the opposite of the usual reason for starting.
It doesn’t work while you pull at your skin. Several popular versions of these exercises involve dragging the skin with your fingers. Repeated over months, that adds to the problem being treated.
If exercise isn’t the answer
Worth saying plainly, because most content on this topic never gets here.
If the softness is fat, the options are clinical, not muscular. If it’s skin laxity, the same. If it’s posture, fix the posture and skip the rest. If it’s tone, ten minutes a day for several months has some genuine evidence behind it and costs nothing.
Knowing which one you’re dealing with is most of the value of this page. The exercises are the easy part.
