Innovative AI Technology for Precision Cosmetic Analysis Developed by ETRI

South Korea’s Electronics and Telecommunications Research Institute (ETRI) has successfully developed an artificial intelligence-based technique capable of meticulously analyzing cosmetics’ spreadability. This new methodology uses vibration signals caused by the act of applying cosmetics to the skin. These signals are then converted into frequency data, which AI evaluates, revealing the product’s absorption over time and detecting subtle differences in spreadability characteristics.

Optimizing Cosmetic Selection with High Accuracy
During the research, ETRI conducted blind tests using 17 different research products from Amorepacific, quantifying the cosmetics’ moisture levels on a scale of 1 to 15. With an impressive accuracy rate of 99%, the institute’s technique is revolutionizing the way we match cosmetics to different skin conditions.

A Leap Beyond Traditional Sensory Evaluation
This breakthrough stands poised to not only save time and costs associated with traditional expert sensory assessment but also to reduce the subjective variance in evaluations, offering a more objective standard. Moving beyond human sensory dependency broadens the horizon for personalized recommendations and consistent quality control.

Broader Applications and Future Aspirations
The potential applications of this technology are vast, from textile feels and paint characteristics to automotive tire traction properties. ETRI’s research initiative, which included collaboration with Amorepacific and electronic device manufacturer Terraleader, has employed a high-precision device for testing cosmetic feel, utilizing a dataset of approximately 5,000 samples for AI deep learning.

Leading the innovative charge, ETRI’s Intelligent Components and Sensors Research Lab’s director stressed ongoing research efforts to analyze cosmetic remnants, thermal sensations, and aspects like fragrance and color. This contribution is expected to bolster the K-beauty industry’s global reputation and demand.

Advancements and Challenges in AI-Powered Cosmetic Analysis

ETRI’s development of AI technology for precision cosmetic analysis represents a significant shift in the cosmetics industry, where personalized skincare routines and products are becoming increasingly important. While the article outlines this innovative use of AI, several related aspects are not mentioned:

1. The importance of non-invasive testing methods for the cosmetic industry, which this technology supports.
2. The potential implications for improving product formulations through more detailed feedback on product performance.
3. How the technology could enable rapid, real-time adjustments in production lines for cosmetics companies, leading to enhanced product consistency.

Key Questions and Answers:

Q: How does this AI technology work to analyze spreadability?
A: The technology uses vibrations generated when a cosmetic product is applied to the skin. These vibrations are converted into frequency data, which AI processes to determine the product’s spreadability and absorption.

Q: What sets this AI technique apart from traditional sensory evaluations?
A: This AI method is more objective, as it reduces the variation and subjectivity inherent in human sensory evaluations. It provides consistent and quantifiable data on product characteristics.

Q: Are there any concerns about replacing human sensory assessments with AI?
A: While AI provides a high degree of accuracy and consistency, there may be concerns about the technology’s ability to fully capture the nuances of human perception, which can be important in consumer satisfaction.

Key Challenges or Controversies:

Some challenges include:

1. Human Sensory Nuances: AI may struggle to fully replicate the subtleties of human sensory feedback, such as detecting complex sensations or the emotional response to a product.
2. Consumer Trust: Convincing consumers and industry professionals that AI can match or surpass human evaluators in product testing.
3. Data Privacy and Ethics: The collection and use of personal data for personalized cosmetic recommendations must be handled securely and ethically.

Advantages and Disadvantages:


Improved Consistency and Objectivity: AI can offer uniform assessments, reducing subjective discrepancies in product testing.
Cost and Time Efficiency: Automation of testing can lead to significant cost and time savings for cosmetic companies.
Personalized Recommendations: AI can analyze a vast array of data to provide tailored cosmetic recommendations for individual skin types and preferences.


Complexity and Cost of Implementation: Initially setting up such an AI system can be complex and expensive.
Job Displacement: There may be concerns about the potential displacement of professionals traditionally involved in sensory assessment.
Potential for Over-reliance: Over-reliance on AI could diminish the development and use of human evaluative skills.
