The visual acne needle is a tool used to remove acne. It has a built-in visualization function that enables users to clearly observe and operate the acne process. The following is a description of the design concept of the visual acne needle:

Built-in camera function: The visual acne needle should have a built-in miniature camera that can capture and display images of acne in real time. This allows users to clearly observe the location, size and shape of acne by connecting to a mobile app or built-in display.

Adjustable focal length and magnification: In order to provide a more accurate and clear observation experience, the visual acne needle should have the function of adjustable focal length and magnification. Users can adjust the focal length and magnification as needed to observe and operate acne in more detail.

LED lighting: In order to provide sufficient light and vision, the visual acne needle should have a built-in high-brightness LED lighting system. LED lights can illuminate the acne area, ensuring that users can clearly see the details and perform precise operations.

Adjustable angle and rotation: In order to facilitate use, the head design of the visual acne needle should be adjustable angle and rotation. Users can adjust the angle and direction of the head as needed to better observe and deal with acne in different locations.

Operating buttons and controls: Visual acne needles should be equipped with easy-to-operate buttons and controls. Users can control parameters such as image capture, magnification, and lighting brightness through buttons to meet individual needs and preferences.

Hygienic and clean design: To ensure hygiene and cleanliness, visual acne needles should be designed with ease of cleaning and disinfection in mind. For example, a removable and washable head design may be used so that the user can thoroughly clean and disinfect the tool.

Battery and charging: The visual acne needle should be equipped with a rechargeable battery system to ensure long-lasting use time and stable performance. At the same time, the charging process should be simple and safe, and can be charged through the USB interface or wireless charging.

It should be noted that when using visual acne needles, users should follow correct operating guidelines and hygiene practices to avoid possible skin damage and infection risks.
