LCD Skin Moisture & Oil Analyzer Pen – Fluorescent Agent Detector, Elasticity & Skin Age Tester

Know Your Skin Before You Treat It.

The Windaily LCD skin detector pen takes the guesswork out of skincare by measuring your skin’s moisture content, oil levels, elasticity, and biological skin age in seconds — while also detecting harmful fluorescent agents in your skincare products. An intelligent chip reads different skin data across different zones, seasons, and environments, giving you a precise picture of your skin’s real condition so you can choose the right products and routine. 8-group memory stores historical readings for before-and-after comparison. CE, RoHS, and FCC certified.

9 Key Functions

• Moisture Detection – Measures skin hydration levels and displays results via color-coded LED: Red = dehydrated / Yellow = normal / Green = well-hydrated
• Oil Level Analysis – Detects excess sebum and oil imbalance across different facial zones
• Elasticity Measurement – Assesses skin firmness and elasticity to track aging or improvement over time
• Skin Age Assessment – Calculates biological skin age based on combined moisture, oil, and elasticity data
• Fluorescent Agent Detection – Tests skincare and cosmetic products for fluorescent agents — a blue response indicates fluorescent agent presence (danger); no blue = product is clean
• 8-Group Memory – Stores 8 sets of historical test data for comparison before and after skincare routines or product changes
• Intelligent Chip – Accurately reads data variations across different facial zones, seasons, and environmental conditions
• High-Precision Probe – Low-resistance elastic probe design for consistent, comfortable contact and accurate readings
• LCD Digital Display – Clear readout of all measurements for instant, actionable skin data

How to Use

1. Charge via USB Type-C (approx. 40 minutes for a full charge).
2. Clean and dry the skin area you want to test.
3. Press the probe gently against the skin surface.
4. Read the moisture/oil/elasticity/skin age data on the LCD screen.
5. To test for fluorescent agents: press the probe against a skincare product; blue appearance = fluorescent agent detected.
6. Short press the “O” key to review the last 8 stored test records.

Frequently Asked Questions

Q: What does the color indicator mean for moisture?
A: Red = skin is dehydrated. Yellow = moisture is within normal range. Green = skin is well-hydrated.

Q: How does fluorescent agent detection work?
A: Apply the probe to the product (e.g., cream, lotion). If the screen shows blue, the product contains fluorescent agents. No blue response means the product is clean.

Q: How many readings can it store?
A: 8 groups of test data. Short press the “O” key to scroll through historical records.

Q: How long does the battery last?
A: Up to 180 minutes of continuous use on a 40-minute Type-C charge.

Q: Is it suitable for all skin types?
A: Yes — the intelligent chip adjusts for different skin types, zones, and environmental conditions for accurate readings across all skin types.
