Specific Features of Training in Safe Manicure and Thin Gel Coating: Comprehensive Analysis of Methodology, Biomechanics, And Dermatological Safety

The relevance of the study is determined by the rapid transformation of the global nail service market, where, against the background of growing demand for services, there is an increase in the incidence of iatrogenic onychodystrophies caused by aggressive treatment techniques and errors in the architecture of artificial coatings. The aim of the work is to provide a scientific rationale for and systematize the methodology of training in safe manicure that integrates medical standards of asepsis, the biomechanics of polymer materials, and the ergonomics of the technician’s work. The study employed methods of systematic review of specialized literature, comparative analysis of hardware technologies, and examination of the physicochemical properties of modern gel systems. The results obtained demonstrate that the implementation of wet cuticle processing techniques and protocols for applying thixotropic gels in a thin layer (without leveling) significantly reduces the risks of thermal burns, contact dermatitis, and traumatic onycholysis. Key principles of instructional design for advanced training courses are formulated, based on psychomotor regularities in the acquisition of manual skills. The practical significance of the work lies in the creation of an evidence base for the standardization of next-generation educational programs. The information presented will be of interest to practicing manicure technicians, instructors, technologists of cosmetic brands, and managers of beauty salons oriented toward the premium segment and client safety. In the end, it provides a collection of design patterns for the building of RTC services that can withstand active network threats and are less susceptible to abuse.
