The Newtone family of solutions specializes in creating and developing increasingly powerful customized interpretation algorithms and acquisition systems, to help Cosmetic Industry to Innovate, Explore and Develop new products for all countries.
One challenge addressed by Newtone is to develop solutions enabling to measure “ground truth”: what the consumers actually see in their mirror. To help investigate moisturizing product performance, Newtone developed a specific optical solution and algorithms, for a combined approach using local visible light and 3D imaging with powerful algorithm for the analysis of skin micro-relief pattern.
Newtone portable high-resolution camera allows rapid at-contact acquisition and analysis of versatile skin features: colour and complexion, lentigos, acne, etc., but also topographic features such as wrinkles, fine lines, or roughness. Its capabilities have now been evaluated for several years, either under nomadic conditions (by the consumer, at home, under real conditions of life), or under controlled conditions, by a technician, at the clinical lab.
It proved its efficiency to follow-up skin changes overtime to various face, scalp, or body locations (hands, forearms, legs, feet etc.).
One research was presented to the ESDR congress in September 2020, showing how this approach enables to measure and compare moisturizers efficacy overtime, under a nomadic context, versus untreated skin by analysing skin microrelief and monitoring its changes upon moisturizers application, to the forearm (poster available upon request).
Indeed, the skin surface roughness is an indicator of major interest for dermatology and cosmetology. Increased in xerotic skin or irritation, it is one of the most common frequent dermatological disorders. In addition to the discomfort triggered by dry skin, the associated roughness and unevenness degrade the appearance of the skin. Yet even a young and healthy skin presents a pattern of fine and isotropic microrelief that contributes to its resistance and to the skin’s soft and velvety aspect due to the light scattering it induces.
It consists of polygonal plateaus, mainly triangles or quadrangles, delineated by furrows.5 7 These furrows are classified according to their length and depth. The only ones visible with naked eye are the primary lines, the widest and the deepest (30-100µm deep relative to the skin surface), while secondary lines are shallower (5-40µm) and narrower. Many intrinsic and extrinsic factors influence the skin microrelief, including skin dryness.
Objective and quantitative evaluation of the skin microrelief is an essential aspect of dermo-cosmetic, especially when it comes to claims substantiation. Newtone camera, connected in real-time to data storage and analysis servers, combined with software suites, proved its potential in analyzing the skin microrelief various parameters under moisturizing effects, sometimes showing a longer efficacy lasting than when measured with classical method (corneometry).
