Abstract:
A controlled exposure method was developed to predict dry skin improvement from a new in-shower body lotion product form. An in-shower body lotion is used in the shower after cleansing, and methods for cleansers and leave-on lotions are not applicable. Protocol parameters were chosen on the basis of consumer habits and practices studies and randomized clinical testing. The resulting protocol is consumer-relevant, and reliably and reproducibly predicts dry skin improvement from the in-shower body lotion product form.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
Characteristics of Dry Friction
Before the wheelbarrow starts moving, the static frictional force acts tangentially to the contact surface, opposing the force that is about to induce the motion. This frictional force prevents the...
