In-Use Test Under Dermatological Control

Supervised In-Use Test under Dermatological Control

This study is a 21-day supervised in-use test with 20 volunteers representing all skin types, conducted under the oversight of a qualified dermatologist. The study includes clinical evaluation and final dermatological sign-off, providing medically supervised data on product tolerance and performance under real-use conditions.

Because many cosmetic and personal care products are intended for repeated skin contact, this study helps evaluate how products perform over time while ensuring clinical oversight.

Study Purpose

This study evaluates how a product performs when used on the skin under normal conditions. It focuses on:

• Skin tolerance
• User comfort
• Cosmetic acceptability

It also helps determine whether repeated use may lead to irritation or adverse skin reactions.

Study Design

The study follows a controlled, supervised in-use design over 21 days at a clinical site.

• 20 volunteers representing all skin types participate
• Participants use the product as directed under normal conditions
• A dermatologist oversees the study and performs clinical evaluations
• A final medical review and sign-off is provided

This approach ensures that results reflect real-world product use while maintaining clinical rigor.

Study Population

Participants are selected to represent a range of skin types based on the intended product use.

All participants:

• Are in good general health
• Have no active skin conditions at study start

This ensures that observed effects are attributable to the product rather than unrelated factors.

Evaluation Criteria

Clinical and subjective evaluations are conducted throughout the study.

Clinical assessments may include:

• Redness
• Dryness
• Irritation
• Scaling
• Sensations such as stinging or burning

Participants also complete structured questionnaires to assess:

• Comfort
• Skin feel
• Overall product acceptability

Both clinical observations and user feedback are included in the final evaluation.

Claims Supported

This study can support a range of marketing and safety claims, including:

• Dermatologist tested
• Dermatologically tested
• Clinically tested
• Tested under dermatological control
• Suitable for all skin types
• Gentle on skin (subject to results)
• Non-irritating (subject to results)

Final claim support depends on study outcomes and applicable regulatory guidance.

Data Review and Reporting

At the conclusion of the study:

• Data is summarized using descriptive analysis
• A clear and structured report is issued
• A final evaluation and sign-off by the dermatologist is included

The report is suitable for use in safety documentation, regulatory submissions, and marketing support.
