In the clinical trial, subjects applied the lip cream or were untreated and evaluated using transepidermal water loss (TEWL), corneometry, visual assessments of lip dryness, expert photographic evaluations, and subject-rated outcomes.

This report explores dry-skin models to assess the potential of a new lip balm formulation to hydrate dry skin or lips, and presents sun protection factor (SPF) values for five new lip balm formulations. Evaporimeter [for transepidermal water loss (TEWL)], Skicon, and Corneometer were used to measure hydrating effects of lip balm formulations in a dry-skin leg model, and TEWL, DermaLab Moisture Meter, Corneometer, and visual assessments were used with a dry-lip model. SPF studies were conducted in accordance with either the U.
