Аннотация: (English) 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.
