简要总结
The goal of this clinical trial is to learn if an anti-redness emulsion can help lower facial redness caused by heat in healthy adult women. The main questions it aims to answer are:
- Does the anti-redness emulsion lower facial redness better than purified water?
- Is the product safe and comfortable to use?
Researchers will compare the anti-redness emulsion to purified water using a split-face method.
Participants will:
- Receive infrared light on their face to trigger redness
- Apply the anti-redness emulsion to one side of their face and purified water to the other side
- Have their facial redness measured at different time points using photography, imaging devices, and skin redness tests
- Answer questions about their experience with the products

结局指标
主要结局
Change in skin redness visual score (Griffith 10-point scale)
时间窗: Baseline to 2 hours post-application
Skin redness will be assessed by a dermatologist using the Griffith visual 10-point scale on the left and right sides of the face. Higher scores on the Griffith 10-point scale indicate greater skin redness, which is considered a worse outcome. Assessments will occur at Tbefore (before infrared induction), T0 (after infrared induction), T10min (10 mins post-application), T1h (1 hour post-application), and T2h (2 hours post-application).
次要结局
- Change in facial redness area ratio (Visia 7 image analysis)(Baseline to 2 hours post-application)
- Change in erythema index (Mexameter® MX 18)(Baseline to 2 hours post-application)
- Change in red blood cell (RBC) concentration measured by TiVi 700(Baseline to 2 hours post-application)
- Change in facial skin temperature measured by thermal imaging (Fluke TiS60+)(Baseline to 2 hours post-application)
- Subject self-assessment of product efficacy and tolerance(15 minutes post-application)
