Why you have a double chin in the first place

Before you pick up a stone, it helps to know what you are actually working on. A "double chin" is a catch-all term for three very different things, and gua sha only addresses two of them well.

1. Fluid and lymph stagnation

The submental area (the soft pocket directly under your jaw) is a dumping ground for lymphatic fluid. When drainage slows — from salty food, alcohol, poor sleep, long hours at a screen, or simply waking up — fluid pools there and creates a soft, puffy second chin. This is the most common cause, especially in people under 35, and it responds to gua sha within a single session.

2. Platysma tension and forward head posture

Hours of looking down at a phone shorten the muscles at the front of your neck and lengthen the ones at the back. The platysma grips, the skin bunches, and what looks like fat is actually a tight, rolled muscle. Gua sha releases this beautifully.

3. Submental fat

Sometimes it is fat — genetic, hormonal, or weight-related. Gua sha will not remove fat cells. It will sharpen the jawline around the fat pad, which often makes the whole area look smaller, but we won't pretend a stone replaces Kybella, CoolSculpting, or losing weight.

So: if you can press under your chin and feel soft, squishy, slightly tender tissue, you are mostly dealing with fluid and tension. That is gua sha's territory.

How gua sha reduces the appearance of a double chin

Three mechanisms, all well documented in manual lymphatic drainage research:

• Lymphatic drainage. Light, directional strokes push stagnant fluid out of the submental basin and down toward the supraclavicular nodes above your collarbone — the body's main drain.
• Myofascial release. Medium pressure along the platysma and under the jawbone releases the tight fascia that is pulling your skin inward and down.
• Increased microcirculation. Gentle friction brings blood to the surface, which temporarily plumps and tightens thin neck skin.

None of this burns fat. All of it changes how the area looks in the mirror.

The exact technique: 4 strokes for the submental area

You need a gua sha with a concave curve that actually fits under the jaw. A flat heart shape will skip across the bone. Our BY RITUEL Amethyst Gua Sha has a deep concave edge cut specifically for the jaw-to-neck curve — it is the edge we use for every stroke below.

Prep: clean face, 3–4 drops of facial oil on the neck and under the jaw. Oil is non-negotiable — dragging a stone on dry skin will irritate you and do nothing for drainage.

Stroke 1 — Submental sweep (the main event)

Tilt your head slightly up. Place the concave edge of the stone flat against the soft tissue directly under your chin, pointing toward your ear. In one slow, continuous motion, sweep from the center of your chin out along the underside of the jawbone to the earlobe. Light to medium pressure — you should feel the stone gliding, not digging. 5–8 strokes per side.

Stroke 2 — Jawline hook

Hook the concave edge over the jawbone itself, starting at the chin. Glide out to the ear, keeping the stone hugged against the bone. This sculpts the bottom edge of the jaw and pulls fluid out of the submental pocket. 5–8 strokes per side.

Stroke 3 — Neck drainage (do not skip this)

Now move the fluid out of the area for good. Start at the ear, angle the stone downward, and sweep in a long, straight line from below the ear down the side of the neck to the collarbone. This is where the lymph actually drains. Medium pressure, slow speed. 5–8 strokes per side.

Stroke 4 — Front neck release

Tilt the head back slightly. Using the long flat edge, sweep from just under the chin straight down the front of the neck to the top of the sternum. Very light pressure here — the front of the neck is delicate. 3–5 strokes.

Total time: about 4 minutes. Do it every morning on clean, oiled skin. Evenings are fine too, but morning is when submental fluid is worst, so that is where the visible payoff lives.

How much pressure? The honest answer

Light to medium. If you see deep red streaks or bruising (sha), you are pressing far too hard for the neck. The submental area is not the back — it has thin skin, lymph nodes, and the carotid artery nearby. A good test: the pressure you would use to spread butter on warm toast. Firm enough to move tissue, not firm enough to drag the skin.

Realistic timeline: what to expect and when

• Day 1 (5 minutes after): visible depuffing. The submental pocket looks 10–20% smaller. This is real but temporary — it is pure fluid movement.
• Week 1: the morning puff gets smaller and clears faster. Jawline starts looking more defined on camera.
• Week 2–4: consistent daily users see lasting change. The baseline — how your chin looks even before you do gua sha — starts to shift. This is when friends ask if you lost weight.
• Week 6–8: the platysma has genuinely released, posture often improves, and the change holds even on rest days. This is as far as gua sha alone will take you.

If you have not seen any change by Week 4 with daily practice, your double chin is likely fat-based, not fluid-based. That is useful information, not a failure.

What gua sha cannot replace

We keep this short because honesty matters more than the sale:

• Weight loss. If the chin is fat and you want it gone, a caloric deficit does more than any stone.
• Kybella (deoxycholic acid injections). Actually destroys submental fat cells. Gua sha does not.
• Submental liposuction or surgery. Permanent fat removal. Gua sha cannot compete and should not pretend to.

Gua sha is the daily maintenance layer that makes all of those look better, and for a lot of people it is enough on its own.

Pair it with these (or most of the work is wasted)

• Neck stretches. 30 seconds of chin tucks and side-to-side neck rotations before you gua sha. Loosens the platysma so the stone has something to work with.
• Posture. A forward head position creates a double chin in real time. Phone at eye level, screen at eye level, shoulders back.
• Hydration. Counter-intuitive but true — dehydrated bodies retain more fluid. Aim for two liters a day and watch the morning puff shrink.
• Lower salt at dinner. The biggest single lever on next-morning submental fluid.
• Sleep on your back, head slightly elevated. Gravity drains the area overnight instead of pooling it.

Frequently asked questions

How long until I see results from gua sha on my double chin?

Day one for temporary depuffing (within minutes of your first session). Week 2 to 4 for a lasting change in your baseline if you do 5–8 strokes per side every morning. Week 6 to 8 for the full platysma release. Miss more than two days a week and the timeline doubles.

Does gua sha work if my double chin is from fat, not fluid?

Partially. Gua sha will not remove fat cells, but it sharpens the jawline around the fat pad and tightens the overlying skin, which often makes the area look noticeably smaller in photos. For actual fat reduction you need weight loss, Kybella, or a cosmetic procedure. We would rather you know that than waste your time.

Is gua sha on the neck safe during pregnancy?

The face and jawline are generally considered safe with light pressure, but some traditional Chinese medicine practitioners avoid deep neck work during pregnancy because of acupressure points in the area. If you are pregnant, keep pressure very light, stay on the jaw and submental pocket rather than deep front-of-neck strokes, and check with your doctor or midwife first.

What is the best oil to use for gua sha under the chin?

Something light, non-comedogenic, and slippery enough for the stone to glide for 4 minutes without dragging. Rosehip seed oil and squalane are our two favorites — both absorb cleanly and do not clog pores along the jawline. Avoid heavy coconut or mineral oil, which sit on top of the skin and cause the stone to skid.

Can I do this twice a day for faster results?

You can, but you will not double the results. The lymph system has a refractory period — once you have drained the area, it takes hours to refill. A thorough morning session plus a 60-second evening touch-up is the most we would recommend. Pressing harder or going longer causes irritation without payoff.

Will gua sha give me saggy skin over time?

No, when done correctly. The myth comes from people using heavy downward strokes on the face. Under the chin, downward strokes toward the collarbone are correct — that is the natural lymph drainage direction, and the tissue there is meant to drain that way. You are not "pulling skin down." You are moving fluid out.

The bottom line

Gua sha for a double chin is one of the highest-return four-minute habits in skincare — if your chin is fluid, tension, or posture-based. Day one gives you depuffing you can photograph. Week four gives you a baseline shift. Week eight gives you a jawline that holds without the stone. Use a concave-edge tool, use oil, use light-to-medium pressure, do 5–8 strokes per side every morning, and drain outward and down toward the collarbone every single time.

If it is fat, be honest with yourself and pair the ritual with the thing that actually addresses fat. Either way, the stone earns its place in the routine.
