. Investigation of optimal hardware parameters and needle configurations in order to minimize microtrauma to the skin during permanent makeup//Science online: International Scientific e-zine - 2026. - №1. - https://nauka-online.com/en/publications/other/2026/1/6377-2/

Annotation: Permanent makeup is one of the most sought-after cosmetic procedures. However, despite its popularity, there is a problem of skin microtrauma, which can occur due to incorrect choice of device and needle parameters. In this article, we will look at the key factors affecting the safety and effectiveness of permanent makeup. These factors include the diameter and configuration of the needles, the length of their tips, as well as the depth and rate of penetration of the pigment. Assessing the effect of these parameters on the skin and ways to optimize them will help minimize tissue damage and improve the safety of procedures. The article will provide recommendations for improving permanent makeup technologies, including the use of more accurate devices, optimizing needles, and developing better pigments.

. Clinical protocols for aesthetic rehabilitation of the nail apparatus in patients with diabetes mellitus: a comparative analysis of wet and dry hardware treatment technologies//Science online: International Scientific e-zine - 2026. - №1. - https://nauka-online.com/en/publications/medicine/2026/1/02-48/

Annotation: In the context of the global increase in diabetes mellitus, which by 2024 has affected 589 million people, ensuring the safety of aesthetic procedures becomes a priority task in podology and dermatology. The present study is devoted to the substantiation of standards for safe manicure in patients with endocrinological disorders who have a high risk of injury due to diabetic neuropathy and angiopathy. The aim of the work is a comparative analysis of the effectiveness and safety of dry and wet hardware technologies for nail plate treatment. The research methodology is based on a systematic literature review, analysis of ADA and IWGDF clinical guidelines, as well as a retrospective case study of the author’s practice. The results demonstrate that the use of wet spray technologies makes it possible to maintain the temperature in the treatment area below the protein coagulation threshold (<40°C) and reduces the concentration of respirable bioaerosol by 90%, which is critically important for the prevention of infectious complications. In conclusion, it is stated that there is a need to introduce hydro-burring as the most appropriate option for diabetic patients, excluding aggressive cuticle removal. The information contained in this article will be of interest to practicing podologists, nail service specialists, dermatologists, and endocrinologists seeking to improve patients’ quality of life.
