Boots carries out studies and in-use tests on healthy volunteers to ensure our cosmetics, toiletries and skincare products meet the required standards before they go on the shelves in store. All our studies are co-ordinated through our purpose built Product Evaluation Suite.

Home user studies involve using products at home and completing a questionnaire about the product.

Controlled user studies involve volunteers visiting the Evaluation Suite. This could be a one off visit for example a focus group or several visits over several months for example an anti-wrinkle study.
