Acne is a skin disease that often occurs during hormonal changes, particularly during adolescence and adulthood (50% of 20-29 years old and 4% of 40-49 years old are affected). Acne can have real psychological repercussions and alter the quality of life by inducing mood disorders, depression, alteration of self-image, relational difficulties… In severe cases, acne can also leads to the formation of scarring lesions causing, in the most serious cases, a grainy appearance of the skin.

Acne is characterized by different stages: a mild acne with open or closed comedones, a moderate acne characterized by papules or pustules, a severe acne with the presence of nodules or cysts.

Newtone’s challenge is to provide solutions to quantify the effect of different products on different acne lesions.

ColorFace®: focus on the holistic approach

The face is the area most affected by acne. The ColorFace®, a full face imaging system, allows a standardized image acquisition under 3 positions and different lighting (including UV) in order to highlight the different types of acne lesions. As the ColorFace® is a connected system, all the images of the study are recorded on the Newtone server in order to view or analyze the images as soon as the acquisition is made even at the other side of the world! On these images, Newtone offers image processing algorithms adapted to phototypes in order to extract open comedones, porphyrin, post inflammatory lesions (erythema and hyperpigmentated lesions) and pores. These algorithms can highlight the cosmetic effects of products, especially since they can be correlated with the consumer perception. Newtone also offers to follow the evolution of the gloss on the images in correlation with the production of sebum on the face.

SkinCam®: focus on the local lesion

In addition to the face, the neck and back are areas prone to acne. With the SkinCam®, Newtone offers a nomade system to make acquisitions of these areas. Its simple use allows the Skincam® to be used in the laboratory as well as at home, so that the subject can acquire his lesions every day to study their evolution. In addition for the analysis of the surface or the visibility of the lesion through its color, the SkinCam® offers 3D reconstructed images to evaluate the roughness of the analysis area or the depth of a scar for example.

PAHPI grading tool developed by Newtone:

In order to evaluate the severity of post inflammatory pigmented spots, dermatologists use the acne hyperpigmentation index (PAHPI grading). This index is based on 3 criteria: the number of lesions, the mean size of the lesions and the mean intensity of the lesions. This scoring is performed directly on the subject. To upgrade this grading, Newtone has developed a digital tool allowing to perform the PAHPI grading on standardized images, thus facilitating the implementation since the dermatologist and the subject do not need to be present simultaneously. The obtained results are more robust than the ones in vivo because the grading can be done blindly without influence for the scorer. The tool is easy to use and can be made available to dermatologists.

In order to offer a complete service and to facilitate the implementation, Newtone offers the realization of PAHPI grading by its medical expert.

Innovative illustrations

Thanks to its scientific and innovative visuals, Newtone is able to highlight the effect of visible products on the skin using data from imaging systems or not. With the Newtone average face technology, Newtone is able to extract the skin of a selected case from a study to apply it on an average face: it is now possible to scientifically illustrate before / after effects without the limitations of the right to image!
