Anti-itching device: a magical gadget that scientifically relieves mosquito bites Introduction
In addition to the high temperature, the most annoying thing about summer is the unbearable itching after mosquito bites. Scratching not only easily leads to skin damage and infection, but may also leave ugly scars. Although traditional anti-itching methods such as applying wind oil and floral water are effective, the effect is short-lived, and some products contain irritating ingredients. In recent years, the anti-itching device (anti-itching device) has emerged to quickly relieve itching through physical or technological means, becoming a new choice for many people. Today, let's talk about the principles and types of anti-itching devices and how to choose the right product for you.
Working principle of anti-itching device
The core goal of the anti-itching device is to block the transmission of itching signals. The mainstream technical principles on the market currently include:
Thermotherapy anti-itching (local heating)
Principle: Destroy the itching protein (such as histamine) in the mosquito saliva through instant heating (about 50°C), thereby blocking the itching signal.
Advantages: Quick effect, no chemical stimulation, suitable for children and sensitive skin.
Representative products: electronic anti-itch pens such as Bite Away and Mosquito Click.
Cold compress to stop itching (icing and soothing)
Principle: Use low temperature to shrink blood vessels, reduce inflammatory reactions, and reduce nerve sensitivity to itching.
Advantages: Suitable for bites with sensitive skin and obvious redness and swelling.
Representative products: Some ice-sensing anti-itch devices or directly use ice packs for cold compresses.
Microcurrent anti-itch (electrical stimulation interference)
Principle: Use weak current to interfere with nerve signal transmission, so that the brain temporarily ignores the itching.
Advantages: No heat or cold sensation, suitable for users who do not like temperature stimulation.
Representative products: Some anti-itch bracelets or electrotherapy anti-itch pens.
Vibration massage to stop itching
Principle: Use high-frequency vibration to distract the nerves from the itching, similar to "stop itching with pain".
Advantages: No chemical ingredients, suitable for carrying around.
Disadvantages: The effect varies from person to person, and it may not be completely relieved.
How to choose an anti-itch device that suits you?
According to the need for relieving itching

Want to relieve itching quickly → Choose a heat therapy type (such as Bite Away).
Sensitive skin, afraid of heat → Choose a cold compress type or microcurrent type.
Like physical massage → Choose a vibration massage type.
Portability
For home use → You can choose a slightly larger cold compress device or heat therapy device.

For outdoor use → USB charging or pen-shaped anti-itching device is recommended.
Safety
For children → Give priority to low temperature or vibration type to avoid high temperature burns.
Pregnant women or people with sensitive skin → Avoid products containing chemical ingredients.
Battery type vs. rechargeable type: Rechargeable type is more environmentally friendly, but battery type is easy to replace.
Whether consumables are needed: Some cold compress devices need to be paired with gel sheets, while heat therapy devices generally do not require consumables.
Tips for using anti-itching devices
✅ Best time to use: Use immediately after being bitten for the best effect (especially heat therapy type).
✅ Combined with topical medications: first apply calamine lotion or mint cream, then use an anti-itching device to enhance the effect.
❌ Avoid overuse: high-temperature type should not be used on the same part more than 3 times a day to prevent low-temperature burns.
❌ Do not use when the skin is damaged: using it on the wound may aggravate the irritation.
