The 3nh PS08 is a research-grade skin analyzer tailored for cosmetics R&D, aesthetic medical efficacy evaluation, and synthetic skin verification. Utilizing a D/8 integrating sphere optical system and supporting simultaneous SCI/SCE measurements, a single skin-contact reading outputs four core indicators: Melanin Index (MI), Erythema Index (EI), Individual Typology Angle (ITA°), and CIE L*a*b* colorimetric values, providing high-precision, traceable skin color data. The core advantage of the PS08 lies in translating international standard colorimetry into objective, quantifiable, and traceable tools for skincare and medical aesthetics, substituting visual guesswork with authoritative data for formula screening, treatment tracking, and personalized skin consultation.

1. 4-in-1 Multi-Dimensional Skin Insight in One Touch

A single measurement outputs four core parameters simultaneously:

  • Melanin Index (MI): Measures skin pigmentation level to evaluate whitening product efficacy, monitor spot changes, and track post-sun repair.

  • Erythema Index (EI): Evaluates skin sensitivity, post-treatment recovery in medical aesthetics, and anti-allergy formulation efficacy.

  • Individual Typology Angle (ITA°): Scientifically classifies skin tone typology, eliminating subjective color guessing.

  • CIE L*a*b* Color Space: International color language for precise skin coordinate mapping.

2. Research-Grade Accuracy Free from Visual Interferences

Combines a D/8 optical structure with planar grating spectrophotometry, fully compliant with CIE, GB/T, ASTM, and ISO standards. Immune to ambient lighting, surface gloss, or visual fatigue, enabling long-term, longitudinal comparative tracking.

3. Skin Longitudinal Tracking & Multi-Zone Profiling

Each measurement is automatically recorded, allowing users to organize and archive data separately for different body areas, such as the face, neck, chest, and arms. By comparing measurements taken on different dates, including MI, EI, ITA°, and Lab*, users can intuitively determine whether a skincare product is truly effective in reducing dark spots, whether sunscreen effectively helps prevent skin darkening, and whether skin redness is gradually reduced. Measurement data is stored chronologically, allowing users to export the data or generate trend charts to visualize changes over time.

  • Independent Profiles for Multiple Body Areas: Create separate profiles for the face, neck, chest, arms, and other body areas, enabling zoned management of skin condition across the entire body.

  • Clear Visualization of Changes: MI, EI, ITA°, and Lab* can all be compared and analyzed. Let the data speak for itself and objectively evaluate skincare results.

  • Product Efficacy Comparison: Compare measurements taken before, during, and after product use to quantify the actual effects of whitening, soothing, and sun-protection products.

  • Local Data Storage: Data is stored locally and is not uploaded to the cloud (optional), ensuring maximum privacy and confidentiality.

  • Let the Data Speak for Itself: No more guesswork in skincare. Let numbers provide objective evidence of skincare results.

4. Objective Data Content Generation for Influencers & R&D

For Skincare Influencers, Beauty Experts, and Ingredient Enthusiasts:

  • Evaluate Sunscreens: Compare EI values before and after sun exposure to assess the effectiveness of sun protection.

  • Validate Brightening Serums: Continuously monitor changes in ITA° values to objectively evaluate brightening results over time.

  • Track Skincare Treatments: Monitor the erythema index to observe how quickly skin redness subsides throughout the treatment process.

Generate Data-Driven Reports: Move beyond subjective impressions and establish professional credibility with research-grade measurements and objective data.

5. Advanced Colorimetric Analysis Capability

Supports CIE LAB, XYZ, Yxy, LCh color spaces and ΔE*ab color difference calculations. Provides clear axis definitions:

L* (Lightness): Lightness axis (0 = pure black, 100 = pure white); higher values indicate lighter skin tones.

a* (Redness): Red/Green axis; positive values measure redness and inflammation intensity.

b* (Yellowness): Yellow/Blue axis; correlates directly with tanning and melanin deposition.

FAQs About PS08 ColorReader

CIELAB L*a*b* values are the most standardized units in the use of color measurement. These determine values of lightness (L*), red-green (a*), and blue-yellow (b*). The color differences between the two samples can be measured through ΔE.

The color measurement test applies a colorimeter or spectrophotometer to evaluate the way a sample reflects or absorbs light. It is given in objective color values (L*a*b*, RGB, or absorbance) and is usually contrasted to a standard in quality control or compliance.

The measurement of color varies according to context in several units. Such common units are L*a*b* (CIELAB), RGB (Red-Green-Blue), and color difference (Delta E). In light absorption, there are no units assigned to absorbance. But the quantitative analysis of absorbance obeys Beer's Law in colorimetry.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.
