The Makeup Durability “Long-Lasting” – Technical Assessment is a combined expert and instrumental evaluation designed to assess the performance of cosmetic products over time.

This test uses visual grading supported by standardized imaging to objectively document how well a product maintains its appearance, providing evidence for claims such as “long-lasting,” “extended wear,” and “all-day performance.”

Purpose of the Test

The goal of this test is to determine whether a cosmetic product maintains its visual integrity and performance over a defined period of time under normal conditions of use.

It is particularly relevant for makeup products such as foundations, lipsticks, mascaras, and other long-wear formulations.

Methodology

The study is performed as a clinical expert assessment supported by instrumental imaging, enabling objective documentation of product performance over time.

• Number of volunteers: 5 or 10
• Measurement points: Baseline (T0) and multiple time points (e.g., up to 8h, with optional extended evaluations at 12h, 16h, and 24h)
• Duration: Defined according to selected protocol
• Evaluation methods: Visual grading and standardized photographic documentation
• Number of samples required: 6 or 11 finished product samples

Test Procedure

1. Volunteer selection:
   Ten participants representative of the target consumer group are selected.
2. Baseline assessment (T0):
   Product is applied under controlled conditions and initial appearance is documented.
3. Product wear period:
   Participants wear the product under normal daily conditions.
4. Follow-up assessments:
   Product performance is evaluated at defined time points (e.g., 8h, 12h, 16h, 24h).
5. Data comparison:
   Changes in appearance are analyzed using visual scoring and image comparison.

Parameters Evaluated

• Makeup durability over time — structured expert scoring
• Visual integrity of the product — coverage, uniformity, and finish
• Changes in appearance — fading, migration, or loss of definition
• Before/after and time-point comparison — supported by standardized images
• Overall long-lasting performance score

Sample Requirements

• Quantity: 11 finished product samples
• Condition: Unopened, stable, and ready-to-use
• Product types: Makeup products intended for long-lasting wear

Results & Reporting

The laboratory report includes:

• Description of assessment methodology and imaging protocol
• Structured scoring of product durability
• Standardized photographic documentation at each time point
• Comparative analysis over time
• Interpretation confirming long-lasting performance

Why This Test Matters

The Makeup Durability “Long-Lasting” – Technical Assessment provides clear, visual and expert-validated evidence of how a product performs throughout the day.

It supports claims such as:

• “Long-lasting wear”
• “Up to X hours of durability”
• “Maintains appearance over time”

This test is essential for product substantiation, marketing validation, and consumer trust, demonstrating real-life performance through objective evaluation and visual proof.
