EMS Technology: Electrical Muscle Stimulation for Your Well-being and Performance

Electrical Muscle Stimulation (EMS) is an innovative technology that activates muscles through localized electrical impulses, generated from a device and transmitted via electrodes placed on specific muscle areas. These low-intensity or medium-frequency impulses mimic those of the central nervous system, causing controlled, deep, and effective muscle contractions.

Far from being a substitute for traditional exercise, EMS acts as a powerful training complement, helping to achieve physical, aesthetic, and therapeutic goals more quickly, efficiently, and visibly. Its use, initially reserved for elite athletes, is now available to anyone looking to optimize their performance or accelerate rehabilitation processes.

Advantages of electrostimulation

Comprehensive training in less time: a 20-minute session is equivalent to up to 90 minutes of conventional exercise. Deep muscle activation: stimulates muscle fibers that are difficult to reach with voluntary movements. Specific and localized work: allows training specific muscle groups with regulated intensity. Fast and visible results in strength, toning, volume, and muscle elasticity. Increased metabolism: caloric expenditure remains elevated for up to 72 hours after training. Simultaneous stimulation of multiple muscle groups, optimizing time and effort efficiency. Reduction of flaccidity and visible aesthetic improvements in a few sessions. Support in muscle rehabilitation and prevention of atrophy derived from injuries or pathologies. Decrease in muscle pain in therapeutic processes. Increased blood circulation and lymphatic drainage, ideal for sedentary people or those with fluid retention. Minimum risk of injury when working under professional supervision and with precise intensity control. Recommended by physiotherapists and specialists in sports medicine and rehabilitation. Compatible with active lifestyles, allowing you to stay in shape with fewer weekly sessions. EMS is more than a trend: it is a scientifically backed technology with sports, therapeutic, and aesthetic applications. With just 2 or 3 weekly sessions and a balanced diet, you can transform your body and your health efficiently and sustainably.

Questions about the HIHO FINE BUBBLE+e shower head:

Microcurrent is a type of weak current similar to the "bioelectric current" that naturally flows through the human body. Due to its extreme weakness, it is almost imperceptible. The closer you are to the shower panel, the more intense the microcurrent will be. When using "HIHO Microcurrent Mode," bring the showerhead closer to your body (within 15 cm).
No, because its design utilizes hydroelectric power to generate microcurrent, there's no need for charging or electricity costs.
Yes, it can also be used for bathing children. However, do not use the "HIHO Microcurrent Mode" if you have any of the following conditions, as it generates microcurrent (weak current). If in doubt, consult your doctor before use or use modes other than the "HIHO Microcurrent Mode."

  • Individuals with physical disabilities and infants should consult a physician before use.
  • Individuals with metal allergies should consult a physician before use (allergies caused by electroplating may cause skin problems).
  • Individuals with implanted medical electronic devices, such as pacemakers.
  • Individuals with life-supporting electromedical devices, such as cardiopulmonary machines.
  • Individuals with wearable medical electronic devices, such as electrocardiographs.
  • Individuals who are pregnant or may be pregnant.
  • Individuals who have recently given birth.
  • Individuals who feel unwell or experience abnormal sensations.
  • Individuals who have recently undergone surgery.
  • Infants, pets, and individuals unable to express their feelings.

Because the "HIHO Mist" mode produces a mist, the perceived temperature will be lower compared to other shower modes. The finer the mist, the faster the heat will dissipate. The exact temperature decrease depends on your water heater's specifications, so please be mindful when switching modes. Enjoy the pleasant experience of a deep skin cleanse.

Questions about REBIVE Mini XS:

Yes, it can be used daily. As a guide, limit use to twice a day.
Do not use the product for more than 10 minutes at a time. Also, avoid using it continuously on the same area for more than 3 minutes.
Do not use on the head, abdomen, chest, neck, elbows, knees or bony areas such as the spine.
Start with a lower level, like 1, and gradually increase it as you get used to it. Do not press hard on the skin; apply it gently.

Questions about EMS Head Spa Pro:

To avoid skin damage, always use accessories specifically designed for the face.
We recommend using it for 5 to 15 minutes per area, with a total usage time of no more than 30 minutes per day. Start with level 1, the lowest speed, until you get used to it. Perform a patch test before first use.
This product uses MYTREX's exclusive NNR pulse technology. Instead of a sharp, stinging pain, you will feel a suction-like stimulation as the muscles contract. Furthermore, it can be used as a normal electric head spa without needing to be wet.
Try the following:

1- Your skin could be dry. Hydrate it well with water or lotion.
2- The accessory might not be in proper contact with the skin. Avoid contact with hair when applying to the scalp.
3- Increase the level with the EMS level button.
4- Make sure all four accessories are in contact with the skin.

Questions about REBIVE Air:

Yes, it can be used daily. Use up to twice a day as a guide.
Do not use the product for more than 10 minutes at a time. Also, avoid using it continuously in the same area for more than 3 minutes.
Do not use on bones such as elbows, knees, or spine, on joints, ears, eyeballs, and the area around the eyes, near the heart, the front of the neck, or on areas with kidney stones.
