The Science Behind Antera 3D®

Combining 3D reconstruction patented method and multispectral imaging to deliver comprehensive, objective, and reproducible skin characterization from a single acquisition.

The science behind Antera

3D Skin Surface Reconstruction Patented Method

The 3D reconstruction patented method is designed to capture the true surface geometry of the skin using controlled illumination and advanced photometric analysis.

 

The technology employs 6 dedicated LEDs specifically configured for surface reconstruction. These light sources illuminate the skin from defined positions and/or conditions, allowing the system to analyze subtle variations in light intensity and shading caused by topography.

 

From these variations, the software reconstructs a high-resolution 3D model of the skin surface, enabling precise quantification of texture, wrinkles, pores, and volume changes.

 

The focus of this method is strictly geometric information, translating how light interacts with surface relief into accurate depth and shape measurements.

 

This enables objective measurement of physical skin structures, including:

​

  • Wrinkle depth, length, and volume

  • Skin texture and roughness

  • Surface irregularities and micro-relief

  • Volume changes over time

Patented 3D skin surface reconstruction

The 3D reconstruction patented method focuses on creating a precise 3D model of the skin surface, enabling objective measurement of wrinkles, pores, texture and volume features.

Multispectral Imaging

Multispectral imaging

Multispectral imaging, in contrast, relies on 18 additional LEDs emitting specific, narrow-band wavelengths across the visible and near-infrared spectrum.

 

This subsystem is designed to capture optical and physiological information rather than shape. Each wavelength interacts differently with key skin chromophores such as melanin, hemoglobin, and other tissue components, producing distinct reflectance signatures.

 

By comparing responses across these 18 spectral channels, the system generates detailed maps of pigmentation, vascular structures, redness, and other biochemical or functional skin characteristics.

 

In this case, the LEDs are not used for geometry reconstruction but for providing color and wavelength-dependent optical analysis of the skin, enabling precise mapping of tissue characteristics based on how different chromophores absorb and reflect light.

 

This allows detailed visualization of:

 

  • Pigmentation distribution (melanin-related optical response)

  • Redness and vascularization (hemoglobin-related absorption patterns)

  • Skin tone and chromatic irregularities

  • Subtle variations not detectable in standard RGB imaging

Multispectral imaging focuses on objectively quantifying skin chromophores, including melanin and hemoglobin, through the analysis of skin responses to multiple wavelengths of light.
