The use of preparations based on hyaluronic acid modified with amino acids and preparations based on micronized collagen in injection cosmetology

Skin condition often affects a person's emotional state, social interaction, and quality of life in general. Inevitable skin ageing, which is a long-term multifactorial process, includes transformation of tissue and cellular homeostasis, impaired proteostasis, decreased immunity, impaired DNA repair and other pathological processes. Correction of age-related changes in facial skin currently remains one of the most urgent tasks of modern aesthetic medicine. Aesthetic medicine is one of the most dynamically developing areas of modern healthcare. Today, injectable cosmetology provides an opportunity for a pathogenetic approach to correcting age-related skin changes and solving a number of aesthetic problems. Most often, preparations containing hyaluronic acid, micronized collagen, vitamins, amino acids, and trace elements are used for this purpose. This article presents an analysis of literature data devoted to the study of modern aspects of the use and effectiveness of injectable preparations based on hyaluronic acid modified with amino acids and preparations based on micronized collagen in aesthetic cosmetology.
