Everyone has different questions about their skin, but similar questions arise wherever skin is being examined: “What is my skin like today?” and “How can we understand what we see together?”

PIE Co., Ltd. develops and manufactures skin, scalp, and hair analysis equipment and software to help answer those questions. The company has focused on connecting the process of capturing images with light and examining skin information to consultations and research.

A Skin Imaging History That Began in 2001

PIE's technology history goes back to the development of the APHRODITE skin analyzer in 2001 and the SIF hair analyzer in 2003. An early model of the JANUS facial skin analyzer was developed in 2006, and skin imaging and analysis technology continued to advance after PIE Co., Ltd. was incorporated in 2013.

That experience led to products including JANUS Pro Hybrid, JANUS Pro Sunlike, Focuskin, and SIF Pro. Along the way, PIE has considered both how to observe skin and how to make the results easier to understand.

Looking at Skin with Light and Images: JANUS Pro

In skin analysis, rather than drawing conclusions from a single image, it is important to examine information captured under different conditions according to the purpose of the analysis.

JANUS Pro Hybrid and JANUS Pro Sunlike support imaging with normal, cross-polarized, parallel-polarized, and ultraviolet light, as well as front, left, and right facial views. The images can be used to examine areas of interest such as pores, skin texture, and pigmentation, giving the consultant and client a shared screen for their conversation.

Registered Korean patent No. 10-2429443 is referenced in the lighting design of JANUS Pro Sunlike. Alongside the optical structure of its equipment, PIE has developed image analysis technology. Its company history records the development in 2025 of AI models for recognizing pigmentation and detecting and removing facial hair in images. Available features should be checked for the particular product and software version.

According to its company profile, PIE has collected more than 1.6 million skin data records across regions, sexes, and age groups and uses them in analysis.

In 2026: New Ways to View Skin with AI and 3D

The AI-based 3D Face View feature added to JANUS Pro in November 2026 reconstructs photographs taken from the front, left, and right into a single three-dimensional facial view. Users can rotate or enlarge the view to examine skin from multiple angles, change the lighting, or compare two views side by side.

3D Face View can be used when front, left, and right photographs are all available from the same imaging session. It builds on familiar JANUS Pro images to make skin information more intuitive to explore and use in consultations.

In October 2026, an AI Skin Timeline feature was also added to Focuskin. It uses a facial photograph to simulate possible images of skin improvement and aging in a video, providing a way to discuss skin care with customers. The feature shows hypothetical changes; it does not definitively predict a person's actual future appearance or care results. It is supported for front-view measurement results in the 64-bit software.

Separately, PIE is developing a new 3D skin analysis device. At K-Beauty Expo Korea in October 2026, the company introduced a prototype of the device under development, presenting the possibilities of next-generation skin analysis technology.

Experience Built in Research and Practice

Technology for understanding skin can take on broader meaning when used in different environments. According to PIE's company profile, its facial skin analyzers are used at more than 500 locations in Korea, including clinical research organizations, universities, university hospitals, major companies, and dermatology clinics.

JANUS devices have also been used in research. For example, a 2020 study published in Skin Research and Technology used the earlier JANUS-III model to repeatedly measure facial skin characteristics in 70 people.

PIE has introduced and operated ISO 9001 and ISO 13485 quality management systems in its product development and production processes. Understanding an instrument's intended use and measurement environment, and interpreting its results, are also important parts of the skin analysis experience.

Products That Connect Analysis with Consultation and Experience

The way skin information is used varies from place to place. Focuskin can support consultations based on skin images and help explain products or care options. In cosmetics stores and aesthetic salons, it can help customers look at the areas that concern them and begin a conversation.

In 2026, Focuskin was sold to and introduced at pharmacies and cosmetics stores interested in skin analysis, with cases of its use in customer consultations continuing to emerge. Berrynew Pharmacy in Myeongdong, Seoul, uses Focuskin to check skin condition and apply the results in cosmetics consultations.

Beauty Lab Pharmacy in Myeongdong added a Focuskin to the analyzer it was already using because many customers wanted skin analysis. Focuskin has also been installed at the Newpink Doksan, Bongcheon, and Siheung stores, where it is used in consultations to examine skin condition and introduce cosmetics.

In this way, PIE's skin analysis technology extends beyond dermatology clinics and research organizations to places where customers can learn about their skin and choose cosmetics in everyday life.

SIF Pro is equipment for observing the condition of the scalp and hair and reviewing related information. PIE has extended its analysis experience beyond facial skin to the scalp and hair.

DuoRay can be used in stores or experience spaces to view visible-light and UV images together and observe how sunscreen has been applied. It does not measure SPF or PA protection ratings.

A History of Research, Development, and International Expansion

In 2020, an award was received in the export promotion category of the Suwon City SME Businessperson Awards, and in 2024 PIE received the R&D Excellence Award at the Korea Outstanding Enterprise Awards. On Korea's Trade Day, PIE received the US$1 Million Export Tower in 2022, the US$2 Million Export Tower in 2024, and the US$3 Million Export Tower in 2025. In 2025, PIE's products were sold in 89 countries and overseas sales accounted for approximately 73% of total revenue.

PIE has also introduced its skin analysis technology and products at international exhibitions and conferences including Cosmoprof Asia Hong Kong, Beautyworld Dubai, and IMCAS ASIA. These activities reflect PIE's continuing research, development, and international market expansion. At K-Beauty Expo Korea 2026, visitors and international buyers tried the skin and scalp analysis equipment and held consultations, generating considerable interest and purchases.

Helping People Understand and Talk About Skin

The value PIE pursues is to take technology beyond numbers on a screen: providing professionals with information to examine skin and giving customers a starting point for conversations about their own condition. That is why PIE continues to develop skin analysis technology.

Listening to what skin has to say, PIE will continue its research and development.
