With the ethnically and racially diverse subject population available at Stephens’ US testing facilities in Texas and Arizona, why would some companies choose to test their cosmetic and consumer-care products in other countries?

The answers are as diverse as the studies:

  • People of different ethnicities may have different skin concerns.
  • There are cultural differences in how products are used.
  • Some product ingredients and effects are perceived differently in other cultures. For example, a tingling sensation is seen as negative or irritating in Japan, whereas US consumers often perceive it as a positive indication that the product is working.
  • Regulations may require local testing in order to sell in that market, due in part to differences in product classifications. For example, an over-the-counter US product may be considered a cosmetic in the EU or a quasi-drug in Japan, subject to additional regulatory requirements.

As of July 2019, of the more than 300,000 studies registered on www.clinicaltrials.gov, nearly half (48%) are being conducted outside the US. About 5% are multisite, with subjects both inside and outside the US.  Websites such as Centerwatch.com and www.nap.edu describe the attractiveness and challenges of conducting non-US clinical trials of drugs and devices (not cosmetic and consumer care products).
