Clinical trials of new products are done to verify that the product is efficacious. Studies are made on one ingredient, not the entire formula. Claiming "product efficacy," which contains one ingredient among several, may be inaccurate for various reasons: the ingredient may bind to another and form an inactive form, or the ingredient may be effective only in high concentrations, or the ingredient may be active only under certain conditions (eg, fixed pH). Expert assessments are provided by dermatologists, nurses or technicians with years of experience and knowledge of working with the necessary techniques and parameters such as skin lines, pores, dry skin, elasticity, pigmentation and general improvements. Some products do not require tests. It is important to contain a certain concentration of the active ingredient. Different tests are performed to verify the effectiveness. It is important to contain a certain concentration of the active ingredient. Different tests are performed to verify the effectiveness. One of them is a Klegman test, which performs locally in places predisposed to the development of dry skin. The Ganges test includes facial surface lines. Instrumental methods are also used. Two main methods are used in profile geometry - one shoots and the other replicates. Two-dimensional photography analyzes the data obtained on a photograph, the gas-containing electrodynamometer is used in in vitro tests for the viscosity properties of the skin. In the early days of computer research, similar methods were used. This appliance serves to determine the sensitivity of the skin. In vivo tests of yor-sebum, a procedure for determining the content of oils in the skin through a film.
