The skin is a natural bulwark against a multitude of external aggressors, such as UV rays, pollution, chemicals and micro-organisms. Many cosmetic products aim to moisturize and care for this skin barrier. Claims for skin barrier protection have a significant influence on the purchasing process.
As formulators are well aware, the assessment of protective properties is a compulsory challenge before a product can be placed on the market.
Evaluation on volunteers is tricky, due to sensitivity to slight disturbances such as emotional fluctuations, air quality, temperature and movement. This variability jeopardizes the quality of results for product evaluation. In order to guarantee claims such as “protective effect”, “film-forming effect” or “absorbent effect”, it is imperative to use an objective, standardized solution to measure transepidermal water loss (TEWL) in a robust manner.
Against this backdrop, Microfactory, a leading company in the field of in vitro cosmetic testing using microfluidics, is launching a revolutionary innovation: T-Skin®.
This new technology makes it possible to measure TEWL.
T-Skin® is based on the use of microfluidics to combine a polymer skin model with a precise reproduction of skin water evaporation.
T-Skin® ensures standardized TEWL measurement using a single protocol. This process guarantees reliable, accurate results by eliminating the influence of external factors on the data.
T-Skin® represents the first in-vitro test capable of assessing the protective performance of your cosmetic products in just one hour. These measurements generate scientific data to validate the claims made by these products.
During volunteer measurement campaigns, two types of equipment are used. Those that measure flow variation in an open chamber, and those that measure saturation velocity in a closed chamber. Thanks to two integrated sensors, T-Skin® can measure in both modes, leaving the user free to choose the most appropriate. Microfactory can provide services for all these technologies or purchase the equipment itself.
These new technologies mark a turning point in the cosmetics industry, offering objective and reliable methods for assessing product performance.
