Stratum Corneum & Sebum Sampling Kit

Key Features of the Skin Condition Visualization Kit

Easy to use, yet trusted for professional skin evaluation across diverse applications

The Skin Condition Visualization Kit is developed and manufactured in Japan and consists of two tape-based sampling tools: the Corneum Strip Tape and the Sebum Indicator Film.
It has been widely adopted in the cosmetic and pharmaceutical industries as a practical and cost-effective standard for visual skin evaluation.

Designed to address common issues such as size variation, printing defects, and supply inconsistency, the kit ensures stable quality and reproducible results.
The Corneum Strip Tape is subjected to a 24-hour patch test to enhance safety and reduce the risk of skin irritation, making it suitable for professional evaluation environments.

Beyond performance, the kit is valued for its consistency and reliability, and is used by cosmetic manufacturers’ R&D teams and professionals engaged in skin sampling and visual evaluation.

Why the Skin Condition Visualization Kit? —
A diagnostic approach that shows the reality of the skin itself, beyond impressions or numbers

When skin condition is “visualized,” it is often done through specialized devices or digital systems that translate measurements into numerical values.
The Skin Condition Visualization Kit takes a fundamentally different approach by presenting the actual condition of the skin surface through real, visible samples.

By collecting corneum and sebum samples on site and visualizing them immediately, the kit allows both professionals and subjects to see and share the skin condition at a glance.
This direct presentation provides a level of clarity and persuasiveness that cannot be achieved through numbers or impressions alone.

For decades, dermatologists, skin researchers, and skincare product developers have relied on this sample-based approach, not as an alternative to instruments, but as a reliable way to present the skin condition as it actually is.
The strength of the Skin Condition Visualization Kit lies in its ability to communicate the reality of the skin surface clearly and consistently.

The collected samples can also be retained and referenced for further comparison or study, supporting explanation, documentation, and professional discussion.
Compact, lightweight, and easy to distribute, the kit combines practicality with scientific credibility, which is why it continues to be chosen in research, clinical, and professional evaluation settings today.

The Corneum Strip Tape uses a transparent adhesive film that is pressed against the skin to collect the outermost layer of skin cells (stratum corneum).
By analyzing the quantity, size, and thickness of the collected flakes, it helps evaluate skin dryness and roughness.

This tool is suitable for in-store skin diagnostics, online skin analysis, promotional kits, as well as for marketing studies and research applications.
Our Corneum Strip Tape is available in two types:
▪ A round-type disk designed for both research and promotional use
▪ A professional-grade slide, made of plastic, suitable for staining and microscopic observation in research settings

DPRES, DSCAN, and Recording Cards
Enhancing the Reliability of Skin Measurement with Dedicated Devices

For those who want to further increase the reliability of the Corneum Checker, DPRES and DSCAN are specialized devices designed not only to “visualize” but also to provide more precise and objective validation of skin condition. They are highly valued in research, development, and testing environments.

DPRES (Pressure Applicator)

By keeping the pressure constant when applying the Corneum Checker to the skin, DPRES minimizes differences caused by individual handling. This ensures stable corneum sampling and improves data reproducibility in comparative or verification studies.

DSCAN (Scanner for Corneum Strip Tape)

DSCAN measures the transmission rate of collected corneum samples, converting the amount of corneum into numerical data. This allows both visual and quantitative evaluation of subtle changes, making it an essential tool in product development and medical research.

Recording Cards (DC222, DC230)

These cards feature a black printed area where the Corneum Checker with collected corneum can be attached, making the samples easier to observe and examine. The adjacent white space is provided for notes on the collected sample. Recording Cards are also useful in retail settings for sharing skin condition results with customers.

Use Cases of DPRES and DSCAN

・Standardizing reproducibility of corneum sampling in research institutions
・Quantitative evaluation of skin changes during product development
・Objective numerical recording of skin condition in medical and evaluation settings
