Abstract: Introdução: Introduction: Skin aging is a challenge to treat. Objectives: To evaluate the in vitro and in vivo efficacy and clinical safety of a phytoestrogens-based cosmetic in the management of photoaging. Methods: The in vitro investigation was performed using the analysis of the genic expression of fibronectin and procollagen, evaluation of the immunomodulatory activity (proinflammatory and anti-inflammatory cytokines synthesis) and histochemistry and immunofluorescence analyses of the skin and the dermoepidermal junction. The in vivo investigation - performed in 76 women randomized into Group A (phytoestrogens complex cream and SPF 20 twice daily) or Group B (the same product plus a commercially available anti-aging cream applied overnight). The study lasted for 120 days, with physician- and patient-led evaluations, in addition to monthly ultrasound (20 MHz) and photographic analysis. Skin biopsies of the face were performed before and after treatment. Results: The study showed In vitro: increase in the expression of fibronectin, in procollagen, immunomodulator potential, represented by an increase in IL-1α and a decrease in IL-10; improvement in the integrity of the dermoepidermal junction; increase in the viability and thickness of the epidermis; increase in collagen synthesis.In vivo: subjective global improvement of the skin's appearance; reduction in the count and intensity of spots, erythema, skin pores, and cutaneous porphyrin. The ultrasound and biopsy revealed increased dermal density (52.7%) and dermal fibers (22.3%), respectively. Conclusions: The topical use of phytoestrogens-based cosmetics improves the overall condition of the skin.
