Evaluating acne treatments: which imaging methods can be used to objectively assess results?
Whether linked to adolescence, stress, or hormonal imbalances, acne affects a large portion of the population today. Inflammatory redness, pimples, blackheads, shine, enlarged pores: these skin conditions have a direct impact on self-esteem and are at the heart of consumer expectations.
This poses a methodological challenge: demonstrating the actual effectiveness of products on these visible changes. This is where the C-Cube comes in.
✅Metric and colorimetric calibration
✅ Uniform lighting
✅ Reproducibility of images
✅ Quantitative and visual analysis of skin parameters
✅ Reliable on all phototypes
Targeted measures for anti-acne studies
Analysis of the elevation of acne lesions
Inflammatory lesions such as papules can be assessed using 3D reconstruction by stereophotometry. The C-Cube can generate a relief map and extract standardized profilometric parameters from the ISO 25178 standard (Sp, Sz).
Sebum quantification - Oily skin
To evaluate the mattifying or sebum-regulating effect of a skincare product, take a sample of the product directly from the skin surface using a patch and analyze it with the C-Cube. It calculates a sebum index based on the surface area covered by the product.
Pores measurements
The C-Cube produces reliable dimensional measurements thanks to its metric calibration. This makes it possible to detect pore density as well as pore depth and surface area.
Blackheads analysis: size and density
Open comedones (blackheads) can be visualized using C-Cube images.
- Blackhead detection
- Diameter measurement (µm)
- Density calculation
The C-Cube is fully integrated into the evaluation protocols for anti-acne and anti-blemish products. It enables reproducible, objective, and easily interpretable visual analysis, both for experts and for communication with consumers.
