Short term studies are usually performed for products such as moisturisers, mascaras or lip products. These studies usually last 1 or 2 days. Depending on the product type a measurement will be taken before and after product application. For example for a mascara study an image of your lashes will be captured before and after you apply the mascara.
Examples of claims made by short-term studies include: ‘Firms and moisturises skin’, ‘Volumises lashes by x%’
