Self-compassion has become a significant focus in counseling psychology; however, evidence regarding its contribution to counselors' professional well-being remains fragmented. This study examines developmental trends of self-compassion research and its effects on counselors within counseling services through a Systematic Literature Review guided by the PRISMA framework. Searches in the Scopus database identified 130 studies. Inclusion and exclusion criteria were applied based on publication year, document type, language, accessibility, population, and subject matter, yielding 13 eligible articles. To enhance the credibility of the review, the methodological quality of the included studies was assessed by examining the clarity of research objectives, research significance, methodological rigor, conceptual precision, and transparency of findings. Overall, the included studies demonstrated satisfactory methodological quality. The synthesis indicates that self-compassion helps counselors manage compassion fatigue, strengthens resilience, enhances therapeutic relationships, promotes psychological well-being, and supports their mental health. Mindfulness-based interventions and self-compassion programs appear effective for strengthening resilience and improving the overall quality of counseling services. Based on the synthesized evidence, structured self-compassion training is recommended for integration into counselor education and ongoing professional development, encouraging brief practices within supervision, and aligning institutional policies to sustain counselors’ well-being. The review highlights self-compassion as a feasible strategy for maintaining effective counseling practice and recommends future studies employing standardized methodological quality appraisal procedures, culturally responsive interventions, and longitudinal designs to strengthen the evidence base.
