The impact of an authorial combined manicure technique on the morphofunctional state of the periungual area and the stability of decorative coating: results of a prospective observational study

Abstract

Introduction. Disorders of the morphofunctional state of the periungual zone represent a common problem in modern manicure practice, primarily associated with the frequent use of traumatic cuticle treatment techniques that lead to dehydration, microdamage, and impairment of the skin barrier function. This, in turn, negatively affects not only the condition of the tissues but also the stability of decorative coatings and their wear duration. In the context of the growing demand for safe and long-lasting aesthetic outcomes, the implementation of dermatofunctional approaches aimed at restoring the hydrolipid balance and minimizing traumatic impact becomes particularly relevant. Methods. A prospective observational study was conducted in January–February 2026 over a 6-week period involving 42 clients with different baseline conditions of the periungual zone. The study design included a two-stage assessment: immediately after the procedure and after 3 weeks. The methods applied comprised observation, visual-analytical assessment (dryness, microdamage, hyperkeratosis, elasticity, texture), comparative analysis, and quantitative data processing. Results. It was found that the application of the author’s technique resulted in a significant improvement in the condition of the periungual zone: the prevalence of dryness decreased from 73.8% to 38.1% after the first procedure and to 26.2% after 3 weeks; microdamage decreased from 64.3% to 26.2% and 16.7%, respectively; uneven texture decreased from 69.0% to 33.3% and 21.4%. In the long-term dynamics (6 weeks), a cumulative effect was observed: the incidence of hangnails decreased to 14.3%, signs of dryness to 23.8%, and hyperkeratosis to 21.4%. Increased elasticity and stabilization of skin texture characteristics were also noted, accompanied by improved quality and durability of the decorative coating. Conclusions. The author’s technique of combined manicure with oil-based cuticle sealing is an effective dermatofunctional approach that ensures restoration of the skin barrier function, reduction of tissue reactivity, and formation of a stable cumulative effect. The application of this technique contributes to the optimization of the morphofunctional state of the periungual zone and enhances the stability of decorative coatings, allowing it to be recommended as a scientifically grounded tool in modern manicure practice.
