You see it in a photo and your first instinct is to retake it from a higher angle. That fullness under your chin — the one that won’t budge no matter how much you diet — has a name: submental fat. And it’s one of the most stubborn, misunderstood areas on the body.
If you’ve been wondering how to get rid of double chin for good, the frustrating truth is that most people are targeting it the wrong way. This guide breaks down the real causes, what clinically studied methods actually work, and a clear decision framework so you’re not wasting time on the wrong approach.
Whether you’re looking for natural lifestyle changes or faster medical solutions, understanding how to get rid of double chin starts with identifying the root cause — because the cause determines everything about which solution actually works.
What Actually Causes a Double Chin?
A double chin (clinically: submental fat accumulation) happens when fat, loose skin, or weakened muscle collects beneath the chin. It’s not always weight-related — and that distinction matters enormously for treatment.
Four main causes:
Excess body fat — the most common driver. When overall fat increases, the submental area fills in along with it. This type responds well to consistent fat loss.
Genetics — jaw bone depth, facial structure, and where your body prefers to store fat are all inherited. Studies suggest that even lean individuals can carry submental fat due to genetic predisposition alone. This is why lifestyle changes have limits.
Skin laxity — collagen production slows from the mid-30s onward. The skin under the chin loses its firmness and begins to sag. Weight loss can sometimes worsen this, as the fat disappears but the loosened skin remains.
Posture (“tech neck”) — constant downward head position weakens the platysma muscle and causes the chin skin to fold and crease progressively over time.
Knowing which of these is driving yours changes everything about which solution actually makes sense.
Can You Lose a Double Chin Naturally?
Short answer: Yes — if it’s fat-driven. No — if it’s genetic or skin-based.
Spot reduction is a myth that exercise science has consistently disproven. You cannot burn fat from a specific area by exercising it. Chin exercises tone the muscles underneath; they do not eliminate the fat on top.
That said, if your double chin is driven by overall body fat, a sustained calorie deficit genuinely works. Dermatologists note that visible facial changes often appear after losing around 5–8% of total body weight — typically over 6–12 weeks of consistent effort.
For genetic or skin-laxity double chins, natural methods have limited impact regardless of consistency. This is where medical options become genuinely worth considering — not as a shortcut, but as the actually correct solution for the problem.
Fast vs. Slow Results: Know What You’re Choosing
This is a distinction most guides skip — and it’s where people waste months.
Slow route (natural methods): 6–12 weeks minimum. Works for fat-driven double chins. Free. Requires sustained consistency with diet and exercise. Results are gradual and tied to overall fat loss.
Fast route (medical treatments): Days to weeks. Works for fat, loose skin, or genetic causes. Costs money. Results are more targeted and — in many cases — permanent.
Neither is inherently better. The right path depends entirely on what’s causing yours — not how quickly you want results.
At-Home Methods + Exercise Routine
These three approaches work best together. Merge them into a daily habit rather than treating them separately.
Diet — The Real Foundation
A calorie deficit is the mechanism behind all natural fat loss. That simply means consuming slightly less energy than your body burns each day.
Cut high-sodium foods first — they cause water retention and temporary puffiness that can exaggerate chin appearance. Protein helps maintain muscle while you’re losing fat and keeps hunger manageable. Small swaps compound: replace salty snacks with nuts, swap sugary drinks for water.
Hydration alone may help reduce puffiness — most people underestimate this effect. Aim for consistent daily intake rather than a fixed “exact” number, since needs vary by bodyweight and activity.
Posture Correction
Raise your screen to eye level. Bring your phone up to your face — not your face down to your phone. Add chin tuck drills throughout the day: sit tall, pull your chin straight back (not down), hold briefly, release.
Some people notice a visible improvement in jaw clarity within a few weeks of consistent posture correction — faster than any exercise routine and completely free.
Gua Sha Facial Massage
Gua sha does not remove fat. It may reduce fluid retention and morning puffiness, which can temporarily improve chin definition. Technique: gentle upward strokes from the base of the neck toward the chin, then along the jawline. Most useful for people whose double chin looks noticeably worse in the morning.
Don’t expect structural change. Do expect slightly less puffy mornings.
5-Exercise Chin Routine (Do Daily, 10–15 Minutes)
These won’t melt fat on their own — but combined with fat loss, they tone the underlying muscles and improve visible definition.
1. Chin Tuck (best for posture correction)
Sit tall, spine straight.
Pull chin straight back — like making a “turtle neck” motion.
Hold 5 seconds, release.
10–15 reps, 2 sets
2. Jaw Jut (best for submental stretch)
Tilt head back toward ceiling.
Push lower jaw forward until you feel a stretch under the chin.
Hold 10 seconds, return.
10 reps
3. Tongue Press (engages platysma and floor-of-mouth muscles)
Tilt head slightly back.
Press tongue firmly to the roof of your mouth.
Hold 5–10 seconds, release.
10–15 reps
4. Ceiling Kiss (neck and chin activation)
Look up at the ceiling.
Pucker lips upward in an exaggerated kissing motion.
Hold 5 seconds, return.
15–20 reps
5. Neck Side Stretch (overall neck tone)
Tilt head right (ear toward shoulder), hold 10 seconds.
Return to center, repeat left.
5 reps per side
Consistency matters far more than intensity here. Miss a day — just continue the next.
Common Mistakes That Keep People Stuck
Most people plateau because of one of these:
Only doing exercises. Chin exercises tone muscle — they don’t dissolve fat. Without a calorie deficit, you’re strengthening something that’s still covered.
Expecting spot fat loss. If you’ve been “targeting” your chin specifically, stop. Total body fat loss is the only natural route to losing chin fat.
Ignoring posture. Many people have a double chin that looks 30–40% worse than it structurally is, purely because of how they hold their head. Fix the posture, see an immediate visual difference.
Chasing trends like mewing. Mewing (a tongue posture practice) has no clinical evidence for reducing submental fat. It may influence jaw alignment slowly over years — it is not a double chin solution.
Giving up before 8 weeks. Natural results take time. Most people quit at week 3, right before the window where visible changes typically begin.
Medical and Cosmetic Treatments
For genetic or skin-laxity double chins — or anyone who wants reliable, faster results — medical options are legitimate and widely used. A board-certified dermatologist or plastic surgeon can identify in one consultation which suits your anatomy.
Kybella (Deoxycholic Acid Injections)
Destroys fat cells permanently using deoxycholic acid — a compound your body naturally produces to break down dietary fat. FDA-approved for submental use.
Best for: fat-dominant double chins
Timeline: results may appear 4–6 weeks after first session; typically 2–3 sessions needed
Cost: $1,200–$1,800 per session
Downtime: 5–7 days swelling per session
CoolSculpting (Cryolipolysis)
Controlled cooling kills fat cells non-invasively. Results under the chin can be more variable than on larger body areas.
Best for: soft, small, defined fat pockets
Timeline: gradual over 8–12 weeks
Cost: $700–$1,500
Downtime: minimal
HIFU / Radiofrequency Tightening
Heats deep tissue to stimulate collagen production. Does not remove fat — it firms loose skin.
Best for: skin laxity, not fat accumulation
Timeline: progressive improvement over 3–6 months
Cost: $800–$2,500
Downtime: minimal
Submental Liposuction
Direct fat removal through a tiny incision. Fast and reliable with predictable outcomes.
Best for: moderate to significant fat; anyone prioritizing speed and certainty
Timeline: visible change within days; final result by week 6
Cost: $2,000–$5,000
Downtime: 1–2 weeks
Neck Lift (Surgery)
Addresses both fat and loose skin together — the most comprehensive option.
Best for: significant skin laxity, typically patients 40+
Timeline: visible in 2 weeks; final result at 3 months
Cost: $5,000–$15,000
Downtime: 2–4 weeks
Which Method Is Right for You?
Method | Best For | Speed | Removes Fat? | Tightens Skin? | Cost | Downtime
Diet & exercise | Body fat-driven | Slow (months) | Yes (indirect) | Mild | Free | None
Chin exercises | Tone + posture | Slow (months) | No | Mild | Free | None
Gua sha | Morning puffiness | Temporary | No | No | $30–$80 | None
Kybella | Fat-driven | Moderate | Yes (permanent) | Mild | $1,200–$1,800/session | 5–7 days
CoolSculpting | Soft fat pockets | Moderate | Yes | No | $700–$1,500 | Minimal
HIFU / RF | Loose skin | Gradual | No | Yes | $800–$2,500 | Minimal
Liposuction | Moderate–significant fat | Fast | Yes (permanent) | No | $2,000–$5,000 | 1–2 weeks
Neck lift | Fat + loose skin | Fast | Yes (permanent) | Yes (permanent) | $5,000–$15,000 | 2–4 weeks
The decision is simpler than it looks:
Fat-driven double chin? → Diet and exercise first. If you want faster or more reliable results, Kybella or liposuction.
Loose skin? → HIFU or radiofrequency tightening. Significant laxity needs a neck lift.
Genetic / structural? → Lifestyle changes won’t move the needle. Kybella or liposuction are your realistic options.
Posture-related puffiness? → Fix posture and hydration first — free, fast, and often surprisingly effective.
7-Day Jump-Start Plan
This is not a “get rid of your double chin in 7 days” plan. That’s not realistic and anyone who promises it is misleading you. This is a foundation week — the goal is to build habits, remove friction, and start the process that pays off between week 3 and week 8.
Day 1 — Assess + Set Up
Take front and side photos in natural light. Save them.
Remove high-sodium snacks from your kitchen.
Track today’s water intake.
Day 2 — Diet Reset + First Exercise Session
Replace one processed meal with a whole-food option.
Add 2 extra servings of vegetables.
Complete the 5-exercise chin routine for the first time.
Day 3 — Add Cardio + Morning Gua Sha
30 minutes of light cardio (walk, bike, swim).
Try 5 minutes of gua sha after waking.
Posture check at your desk: screen at eye level.
Day 4 — Sodium Audit
Track your sodium today using any free app. Aim to stay under 1,800mg.
Prioritize hydration throughout the day.
Repeat chin exercise routine.
Day 5 — Add Strength Training
Include upper back and core work (rows, planks, deadlifts). Strong postural muscles reduce chin-area appearance over time.
Continue daily chin routine.
Day 6 — Consistency Check
Missed a day? Don’t restart. Just continue. Consistency over perfection.
Identify one thing to adjust next week.
Day 7 — Review + Plan Forward
Take Day 7 photos in the same lighting as Day 1.
Look for small shifts in puffiness or jawline definition — not dramatic transformation.
Set a 30-day goal based on what you’ve learned.
The real results happen between week 3 and week 8. Stay consistent past day 7.
Frequently Asked Questions
Does chewing gum help reduce a double chin?
Mildly. Chewing activates jaw muscles and may contribute to minor toning over time. It won’t remove fat or tighten skin, but as a complementary habit it doesn’t hurt. Use sugar-free gum to avoid extra calories.
How long does it realistically take to lose a double chin?
With natural methods, visible facial changes may appear after 6–12 weeks, typically corresponding to around 5–8% total body weight lost. Medical options move faster — Kybella results may be noticeable in 4–6 weeks, liposuction often shows visible change within days. Individual results vary based on anatomy, consistency, and starting point.
Can skinny people have a double chin?
Yes — and it’s very common. Genetics, jaw structure, skin laxity, and posture all cause double chins in lean individuals. For these people, diet and exercise will have limited impact. Non-surgical options like Kybella or HIFU are typically more appropriate starting points.
Is Kybella permanent?
Yes. The fat cells destroyed by deoxycholic acid injections don’t regenerate. However, significant weight gain after treatment can enlarge the remaining fat cells in the area — so maintaining your weight is important for lasting results.
Can I lose my double chin without surgery?
Depending on the cause — yes. For fat-driven cases, a sustained calorie deficit works. For genetic or loose-skin cases, Kybella and HIFU are effective non-surgical options. Surgery is typically only necessary when skin laxity is significant enough that non-invasive treatments can’t fully address it.
Does mewing actually work for double chins?
There is no clinical evidence that mewing reduces submental fat or meaningfully changes chin appearance in adults. It may influence jaw alignment gradually over years in younger individuals, but it is not a reliable strategy for this problem.
The Bottom Line
A double chin is stubborn — but it’s not permanent. The cause determines the solution. Knowing exactly how to get rid of double chin depends on identifying whether your case is fat-driven, genetic, or skin-related.
Fat-driven? Start with diet and exercise, give it 8–12 weeks, and consider Kybella or liposuction if you want faster or more targeted results. Genetic or skin-based? Stop trying harder at lifestyle changes that won’t fix a structural issue. Consult a dermatologist and explore what’s clinically appropriate for your anatomy.
Start with the 7-day plan above to build momentum. If you’ve put in consistent effort and aren’t seeing movement, that’s not a willpower problem — it’s a signal to re-evaluate the cause and pick the right tool. Learning how to get rid of double chin effectively means matching the solution to the root cause, not just working harder at the wrong approach.
You now have the information to make that call clearly.
