Korean Research Institute Develops AI to Analyze Cosmetic Spreadability with 99% Accuracy

Artificial Intelligence Advances in Skincare Performance

The Korea Electronics and Telecommunications Research Institute (ETRI) has unveiled an innovative technology that harnesses the power of artificial intelligence to analyze the spreadability of cosmetics. Researchers have successfully simulated the act of applying cosmetics to the skin to accumulate relevant environmental data. They were then able to convert the friction values exhibited during the cosmetic application into frequency data, analyzing the complex signals over time to differentiate the characteristics of product spreadability.

By monitoring the vibrations produced by the spreading action and converting them into frequencies, the technology can detect subtle differences as the cosmetics are absorbed into the skin. This process translates into the ability to discern moisture levels ranging from damp to dry. An impressive blind test conducted on seventeen Amore Pacific research products, graded on a scale from one to fifteen, demonstrated a remarkable 99% accuracy rate in recommending suitable skincare products to match various skin conditions.

This innovative approach also promises to streamline the traditional reliance on expert sensory evaluations for spreadability, reducing time, cost, and subjective bias to offer a more objective assessment standard. Moreover, this practice holds potential for applications beyond skincare, from evaluating the tactile qualities of clothing and paint to distinguishing the friction characteristics of automotive tires.

The research utilized a precision device for testing cosmetic texture, a collaborative development between ETRI, electronics manufacturer Teraleader, and beauty giant Amore Pacific. Around 5,000 datasets were used to train the deep learning AI model. ETRI’s Intelligent Component & Sensor Research Laboratory head Yong-Seok Yang emphasized ongoing research to further analyze cosmetics for residue, thermal sensation, fragrance, and color aspects, aiming to propel advancements in the global K-Beauty industry.
