The functional aspects of cosmetics concern both facial and body use.
The researchers in Mérieux NutriSciences continuously develop and update the evaluation methods to create new testing protocols by mixing different analytical techniques.
Mérieux NutriSciences offers state-of-the-art skin imaging applications to evaluate the efficacy of cosmetic products.
An integrated approach with different analytical applications -including new imaging tools- grants the possibility to test the efficacy of cosmetic products.
Imaging techniques are combined with expert clinical evaluation and consumers’ opinions: the aim is to confirm product efficacy, underline its potentialities and provide the producer with sound basis for marketing campaigns.
Mérieux NutriSciences laboratories have highly skilled technicians working on specialized test protocols and advanced technologies (DermaTOP Blue, FrameScan V3®, DermaScan C and SEM) for high quality skin images acquisition.
Here are some examples of digital and quantitative imaging techniques to create a test protocol for claim substantiation.

Picture 2. Images of some wrinkles obtained by DermaTOP Blue before, during and after the treatment with a product under test. The image on the left shows the wrinkle before the treatment: it is deeper if compared to the image on the right.
Picture 3. Two images elaborated by a software for 3D analysis of skin topography (before and after the treatment with the product under test).
Picture 4. CameraScan V3®-FrameScan V3® captures images using pre-set parameters and analyzes skin characteristics by comparing the images recorded at different times (T0, T1, T2, …).
The tool is of utmost quality: cosmetic applications require high sensitivity and reproducibility to allow the evaluation of their efficacy.
Hardware quality (resolution, homogeneous lighting, visio-bench, etc.), all functionalities, metrological levels (quantitative and calibrated measurements) make the difference.
If images are not reproducible or their resolution is insufficient, a clear trend of the effect of the cosmetic product cannot be obtained even with the best image analysis software.
Thanks to this tool, the evaluation of wrinkle visibility, skin color, brightness, homogeneity, redness, pigmentation and mat effect becomes possible. Each aspect is quantified by a parameter: in this way, the difference between before and after the treatment can be measured.
Picture 5. Image software processing to quantify the area. The comparison between before and after the treatment can be evaluated. The improvement generated by an anti-age cosmetic treatment can be measured by comparing the different stages.
Picture 6. This tool is used for ultra-sonic imaging and it measures skin features. The cosmetic treatment efficacy is evaluated by derma density: this parameter evaluates the improvement of both the derma and its components.
Picture 7. The density/echogenicity of a healthy and young skin are higher if compared to an old one.
