International Research Services, Inc. (IRSI) is a privately held cosmetics-focused research company established in 1977 and based in the United States. It concentrates on dermatological safety and efficacy testing and is noted for biophysical instrumental analysis of how test products affect human skin, serving clients with a need to understand skin-related outcomes for cosmetic, pharmaceutical, and nutraceutical applications. In addition to safety and efficacy work, IRSI has experience conducting Phase I–IV clinical trials across a range of indications, including gastrointestinal, metabolic, respiratory, and pediatric safety areas, as well as studies on odor threshold tolerance. The company's client base appears to span the cosmetic and broader life-science sectors that require rigorous human-skin assessment and clinical testing to substantiate product claims and safety profiles. A recent development involves a partnership with Plus One to evaluate the impact of masturbation and orgasm on depression and anxiety, reflecting a diversifyed engagement with clinical research beyond traditional dermatological endpoints.
