Infrared thermal measurement method to evaluate the skin cooling effect of topical products and the impact of microstructure of creams

The sensorial characteristic of topical products determines the patient acceptability of the topical products. The primary focus of the present study was to assess the feasibility of using Infrared (IR) thermal imaging technique to measure the skin cooling effect of topical creams. The secondary objective was to investigate the effect of microstructure of topical creams on the skin cooling effect of topical cream products that are identical in composition. The results showed that IR thermal measurement technique was found to be a sensitive and reliable for quantitative evaluation of skin cooling effect of topical products. The globule size of the creams was found to influence the skin cooling effect caused by creams despite their sameness in composition.
