MichatoLab Jawline Pro

Jawline PRO: 23 kg of resistance, the top of our range

This is the heaviest load we make. You feel 23 kg on the first bite, and so do your masseters. PRO is built for people whose jaw is already used to regular training and who want somewhere further to go.

The mechanics are unchanged. Place it between your front teeth, bite down, push through the resistance. Your chewing muscles get a load that no meal will ever give them, and they respond the way every other muscle in the body does: they grow.

Who should be using 23 kg

People with the groundwork already done. Typically that means several months of consistent training behind you and 14 kg no longer presenting any difficulty, though it also covers those with naturally strong jaws who want the higher load from the outset.

The test is simple: ten minutes on the lighter model leaves you feeling essentially nothing.

Starting from zero? Take Jawline LIGHT at 14 kg instead and move up once your muscles are used to regular work.

Why more resistance moves you forward

The muscle doing the work is the masseter, with the temporalis and the deeper layers of the chewing apparatus joining in as load increases. When the masseter thickens, the jaw angle stands out and the line from ear to chin reads more sharply.

The same rule applies here as in the gym: without rising load, progress stalls. Once muscles have adapted to a given resistance, they have no reason to keep changing. That is the entire argument for the PRO version. It raises the ceiling where the lighter one has run out.

Training with the heavier model

Five to ten minutes a day is plenty, split into shorter sets with a pause. Chew smoothly and under control rather than fast and snapping. At this resistance, technique matters more than session length.

For the first week after switching from LIGHT, halve your usual time. Your muscles know the movement but not this intensity. Then build back up, and keep one or two rest days a week, because muscle grows between sessions, not during them.

Expect six to twelve weeks before changes are visible. Genetics, your starting condition and body fat percentage all affect the pace. Jaw training works on muscle rather than on the fat layer above it, so results show up best alongside general fitness.

Material and build

Even at this load the material stays 100% food-grade silicone with no fillers. Flexible, gentle on enamel, and built to survive long-term compression. The higher resistance comes from the density and structure of the silicone, not from harder additives.

Dimensions of 3.8 × 3 × 3.5 cm and a weight of 30 grams are identical to the LIGHT model. It hides in your hand and in your pocket, which means training in the car, at your desk or on the way home without anyone noticing.
