A handheld optical high-resolution high-power smart skin testing analyzer (100), and a system and method thereof. The analyzer comprises a housing (10), a camera shooting module (20), a high-power optical macro magnification module (30), a comprehensive light source module (40), a first wireless communication module (50), a power module (70), and a control module (80). The camera shooting module (20) comprises a high-resolution optical sensor (21). The comprehensive light source module (40) comprises multiple light sources used for obtaining different levels of information of the skin. Thus, the skin testing analyzer (100) is utilized for freely and flexibly obtaining image information of a skin portion needing to be tested, skin information is sent to a mobile smart terminal by means of the first wireless communication module (50) configured in the skin testing analyzer, and the mobile smart terminal processes and analyzes image or data information thereof so as to determine a skin condition and provide resolving or optimizing suggestions. A user can monitor different levels of health conditions of the skin at any time and any place and check the health conditions synchronously on the mobile smart terminal. The design has the advantages of being smart, convenient to use and carry, high in practicability and the like.L'invention concerne un analyseur de test cutané optique, intelligent, portatif, à forte puissance et haute résolution (100), ainsi qu'un système et une méthode associés.
