The utilization of both systemic and topical treatments in dermatology with the expectation that their combination will enhance attributed benefits and provide preventive dermatology has gained interest. In order to identify effective combined treatments for skin aging, a systematic review was conducted (clinical trials), which comprehensively searched the Capes Journal Portal of E-Journals. Out of the 4543 articles evaluated, only 24 were deemed eligible for final analysis. The findings were characterized as clinical studies that evaluated various combinations of treatments. It was concluded that the efficacy of collagen peptides, antioxidants, moisturizers, and lifestyle changes in mitigating skin aging resulted in improvements in the firmness, elasticity, hydration, and antioxidant protection of human skin.

A systematic review and meta-analysis of randomized controlled trials (RCT) in patients with plaque psoriasis was carried out, comparing the efficacy of herbal treatments alone or in association with other therapies. We comprehensively searched the MEDLINE, Embase, Lilacs and Cochrane Library databases, only including studies published from 2016 to 2020. The certainty of evidence was assessed using the GRADE approach. Results Out of 2,268 articles evaluated, only seven RCT were eligible for final analysis. Five of these studies evidenced low risk of bias and a high level of evidence. Limitations Few RCT of medicinal plants. Conclusion This meta-analysis indicates that medicinal plants may be used as topical or oral products, either alone or combined with other forms of treatment. These products have the potential to greatly improve the quality of life of the patient.
