Letsip® S4 is the second largest of the products in the S series (width 55 mm).
Letsip® S4 for passive training.
- Training of closing the mouth, stimulation of the cheeks and all muscles attached to the lip muscles (m. orbicularis oris).
- Sit with it between your teeth and lip for 20 minutes.
- Go from large size to the smallest orbicules to increase the difficulty level S5/S4 to S2/S1.
- Try not to tighten the chin area (mentalis)
Active stimulation with S4 is worked into the mouth between the lips and teeth.
If active stimulation is given with S4 with fast short vibrations, this will be able to increase the tone in the muscles to contract.
With long-term stimulation of the same muscle, a reduction in elasticity and tone can be achieved.
