Abstract

Introduction and Objective: Aesthetic medicine is a rapidly developing field of medicine that significantly improves patients' quality of life in terms of self-esteem and psychological well-being. Modern laser technologies are not only used for rejuvenation, regeneration, or skin pigmentation removal procedures. Laser treatments play a crucial role in the treatment of acne and post-acne changes, allowing not only to reduce disease symptoms but also to minimize the risk of recurrence.

The aim of this article is to analyze the course and effectiveness of acne and skin scar therapy through the use of laser technologies, as well as the complexity of potential benefits and possible limitations of their risks.

Materials and Methods: This work is based on an analysis of scientific literature concerning the use of laser therapy in the treatment of acne and post-acne scars.

A review of existing bibliography was conducted regarding individual types of laser therapy in relation to post-acne scars and acne dermatosis. The course and effectiveness of therapy using lasers were analyzed.

Results: Literature analysis showed that modern laser technologies provide effective and relatively safe options for treating acne and post-acne scars. Laser therapy yields moderate but clinically relevant improvements in inflammatory lesions, post-acne scarring, and overall skin texture, with minimal risk when appropriate patient selection and operator expertise are ensured.

Conclusions: Laser therapy can substantially enhance outcomes in acne and post-acne scar treatment and contribute to improved patient quality of life. Further studies are needed to establish optimal treatment protocols and to compare the effectiveness of specific laser types across different clinical forms of acne.
