The difficulty in consultations is often not the lack of a device, but whether the information a device produces can be understood, remembered and repeated. The ZETTA 3D skin analyzer puts capture, analysis, simulation and reporting into one workflow, so skin condition moves from something that is merely seen to something that can be shown.
1. Marker-free 3D modeling: getting the capture right first
ZETTA can capture and generate a facial 3D model built to true scale without marker dots on the face, with 3D measurement accuracy of ±0.2mm and mesh density of 0.5mm. The model reproduces details such as pores and fine lines, providing a basis for contour assessment and simulation design.
For front-desk staff and consultants, marker-free means simpler operation: the subject sits down, the device captures around the face and the model is generated automatically, which cuts preparation steps and reduces error from inconsistent marker placement.
2. 56 megapixels and multispectral imaging: layering the problem
The device carries 56-megapixel high-definition texture that shows skin texture, superficial pigmentation and other details. Combined with 3D measurement accuracy, it lets physicians assess overall contour and zoom in on local areas.
Multispectral imaging separates skin concerns into layers: spots, wrinkles, texture, pores, UV spots, brown spots and red areas (capillaries/inflammation) are imaged separately, producing red-zone, brown-zone and UV spot maps. Deep-layer problems that the naked eye can hardly distinguish can be pointed out on these maps.
3. Surround capture: shortening the workflow
The capture module rotates automatically around the face, acquiring frontal, left and right full-face views in one pass without repeated posture adjustment. Total scan time is under 25 seconds, about 3 seconds per single scan; with local algorithm processing, on-site demonstrations do not depend on a network.
The direct change from a shorter workflow is a more continuous consultation rhythm: consultants can operate the device after training, and physicians can spend time interpreting results and discussing plans instead of waiting for the device.
4. Where the device sits in the consultation workflow
ZETTA provides visual skin assessment information that supports consultation communication and outcome records. Clinics can bring data display, before-and-after comparison and client communication into digital management according to their own service workflow, improving service consistency.
The device supports time-series comparison and report output: at follow-up, historical records can be retrieved to view changes between two tests; reports can be exported, printed and archived for case documentation. Note that the actual treatment plan is still determined by the physician.
5. Technical background
Shenzhen Zhongke Zhimei Technology Co., Ltd. originated from the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, and is a national high-tech enterprise focused on 3D medical simulation systems.
According to public company information, the R&D team has worked in 3D computer vision for more than ten years, published over 300 related research papers, filed and been granted more than 100 domestic and international invention patents, undertaken more than 80 research projects including National Key R&D Program projects, and completed more than 20 technology transfer projects.
As of April 2026, CASZM has filed and been granted 68 patents and software copyrights in total (according to public company information). Its 3D digital devices are now used in a number of public hospitals and aesthetic clinics in China.
This device is intended only for skin condition analysis and communication support; it does not replace a physician's consultation, diagnosis or treatment decisions.
