According to the Standard for the Evaluation of Efficacy Claims of Cosmetics, cosmetics with oil control efficacy, should conduct efficacy claim evaluation by efficacy evaluation test in vivo/consumer use test/laboratory test (at least one item must be selected), combined with literature or research data analysis results.
This article is to introduce the Innoderm cosmetic efficacy testing lab's human efficacy evaluation program on oil control.
Oil control efficacy evaluation test
Innoderm cosmetic product testing laboratory uses a photometric method to measure the oil content of the skin. The measuring instrument is a skin oil tester SM815, and the principle of the experiment is that when a 0.1 mm thick opaque matte tape is applied to human skin and absorbs oil, it becomes translucent. As its light transmission changes, the instrument can calculate the skin oil content by the amount of light transmission.
The corresponding measurement interval is set according to the different oil control claims of the product, and the sample is measured 3 times at different locations within the application area and the control area to obtain the oil content of the skin surface in each area, and the measurement results are expressed as the average of the 3 measurements. The entire test cycle usually does not exceed 24 hours.
By comparing and analyzing the data collected, we will be able to know whether a product, can be considered to have oil control effects.
