Frequently Asked Questions

Q: How does the rechargeable anti-itch pen work on insect bites?

A: The pen uses thermal pulse technology combined with gentle vibration. The ceramic heating pad delivers targeted warmth directly to the bite area, which works to break down proteins left behind by insect saliva — the primary cause of itching and skin irritation. Simply select your preferred temperature setting (40°C–51°C) and apply to the affected area for up to 30 seconds.

Q: Is this anti-itch pen safe for children and babies?

A: Yes! The device is designed to be suitable for children, pregnant women, and adults. For young children or sensitive skin, we recommend starting with the lowest heat setting (40°C) and always supervising use on small children. Because it contains no chemicals or creams, it is a gentle, non-invasive option for the whole family.

Q: How long does the battery last and how do I recharge it?

A: The built-in 3.7V/500mAh lithium battery recharges fully in approximately 2–3 hours via the included USB cable. A full charge provides multiple treatment sessions, making it ideal for extended outdoor trips or daily use at home.

Q: Which insects does this device work for?

A: The thermal pen is effective for bites and stings from mosquitoes, flies, bees, ants, wasps, hornets, and other common insects. The targeted warmth helps neutralize the irritants deposited by a wide range of insects.

Q: Does the pen turn off automatically?

A: Yes. The device features a 30-second automatic shutoff function that ends each session precisely, ensuring consistent, safe application and preventing overexposure to heat.
