Timetable Number of pores
Neat skin 782 Time: Immediate 367 Time: 15 minutes 452 Time: 1 hour 449 Time: 3 hours 474 Time: 6 hours 473 - Immediate reduction in number of pores: 53%
- Average reduction in number of pores: 43%
Benefits
- Smoothing of fine lines: Immediate effect and up to 3 hours
- Pores and redness masking: Immediate effect and up to 6 hours
- Soft-Focus Testing Capabilities
The soft-focus benefits of formulations containing Dow specialty silicones have been demonstrated in both in-vitro and in-vivo testing with good correlation between test method results.
In Vitro
Visual Resolution – A cosmetic formulation was coated onto a glass slide covering an ISO Test chart N0 2. Visual assessment performed by a trained operator: The lower the number of lines that could be perceived as not merging, the higher the blur. UV-Visible Spectrometry – A UV-visible spectrophotometer with an integrating sphere was used to measure the optical properties required to achieve the soft-focus effect, and target percentage values were established.
Maximum Total Transmission (TT): Natural skin tone
Maximum Diffused Transmission (DT) and Diffused Reflection (DR): Hides/blurs imperfections
Minimum Total Reflection: (TR) Minimizes shine
Targets: DT/TT > 50%; DR/TR > 80%; TT > 75%; TR < 20%
With the exception of TR (which is an indicator of shine), the higher the value, the greater the blurring effect.
In Vivo
Image Analysis – Testing was conducted using a computerized image analysis system (VISIA-CR or VisioFace). Five pictures were taken before the application of the formulation (neat skin), immediately after application and at subsequent intervals. The images were then ranked by a minimum of 12 evaluators by order of fine-wrinkle intensity on a scale of 1 to 5 (1 = low and 5 = high).
