Abstract The global demand for cosmetic surgery continues to rise, driven largely by societal factors and personal motivations related to self-esteem and psychological well-being. Although previous reviews have examined general psychological outcomes, specific impacts on self-esteem remain underexplored. This systematic review and meta-analysis aimed to synthesize current evidence regarding the effects of non-reconstructive cosmetic surgery on self-esteem in adult patients. A systematic literature search was conducted across multiple databases, including MEDLINE, Embase, Cochrane Library, and others, from January 2005 to March 2025. Studies evaluating self-esteem before and after cosmetic procedures using validated scales were included. The methodological quality was assessed using the Effective Public Health Practice Project (EPHPP) criteria. Data synthesis employed a random-effects meta-analyses using Hedges’ g to estimate effect sizes. Twenty-five studies (n=1502 patients) met inclusion criteria. The overall meta-analysis indicated a statistically significant improvement in self-esteem after cosmetic surgery (Hedges’ g = 0.43, 95% CI: 0.13–0.73; p=0.003). Subgroup analyses demonstrated a significant positive impact particularly in breast surgeries (g=0.59; p=0.006), while facial surgeries showed smaller, non-significant changes (g=0.23; p=0.268). Cosmetic surgery is associated with a small to moderate but significant improvement in self-esteem, particularly after breast procedures.
