BioHito Device

When using the BioHito device, you may experience a slight tingling sensation, mainly because the human body is highly sensitive to electrical currents. Even a very small current can trigger a mild response in nerves or muscles. Here are some key reasons for this sensation:
1. Nerve Sensitivity to Electrical Currents
The human nervous system is highly responsive to external electrical signals. The microcurrent from the BioHito device operates at microampere (μA) or milliampere (mA) levels. When the current passes through the skin, it stimulates nerve endings, causing a mild "electric shock" sensation, such as tingling, slight vibrations, or a pinprick feeling.
2. Differences in Skin Impedance
Each individual and different areas of the body have varying skin resistance (impedance). When microcurrent passes through areas with high impedance (such as dry skin or thickened keratin layers), the sensation may feel stronger. Conversely, areas with more moisture or better conductivity will have a weaker sensation.
3. Frequency and Waveform Effects
Low-frequency levels (1-3): These stimulate nerve endings more significantly, with some users experiencing a noticeable tingling sensation.
Mid-frequency levels (4-7): These currents penetrate tissues more easily and usually produce a stronger sensation.
High-frequency pulses (8-20): Pulsed currents tend to make the nervous system more sensitive to electrical signal variations. However, once you get used to it, it feels completely fine.

4. Poor Contact Between Skin and Electrodes
If the device's electrodes do not make even contact with the skin, localized current density may increase, causing a stronger sensation in certain areas.
5. Individual Differences
Everyone has different nerve sensitivity. Some people feel the microcurrent more intensely, while others barely notice it.

How to Reduce the Tingling Sensation?
1. Use gel-type lotion: This helps reduce skin resistance and improves current uniformity.

2. Adjust the current intensity: Start at a low setting and gradually increase to a comfortable level.

3. Keep your skin hydrated: Dry skin has higher resistance, which may cause stronger sensations.

4. Avoid high-sensitivity areas: Try not to touch BioHito with your fingertips or toes, as these areas have dense nerve endings. For proper usage, please refer to the instructional video.
