Estudo de Pele Saudável Natreon - Suplemento PrimaVie

1 de junho de 2026 atualizado por: Gayle Gordillo, Ohio State University

A capacidade de um suplemento oral de melhorar a microperfusão, a hidratação, a elasticidade e a função de barreira da pele

Este estudo demonstrará a capacidade do suplemento oral PrimaVie® de melhorar a microperfusão, hidratação, elasticidade e função de barreira da pele. 45 mulheres serão inscritas em 1 de 3 braços onde receberão 125 mg de PrimaVie, 250 mg de PrimaVie ou placebo (controle) para tomar duas vezes ao dia por 14 semanas.

Visão geral do estudo

Descrição detalhada

Os indivíduos serão avaliados com base no tipo de pele Fitzpatrick que possuem, retornarão para um total de 6 visitas de estudo durante 14 semanas, onde as seguintes atividades de pesquisa ocorrerão ao longo do estudo: histórico médico/dietético, medicamentos serão ser registrado, a randomização do suplemento com base em um dos três braços ocorrerá na visita do estudo 1 e a distribuição do produto do estudo ocorrerá em todas as visitas do estudo, avaliação da tolerabilidade do suplemento, avaliação da aparência do investigador e do sujeito, fotografia da face (esquerda, direita e frontal), avaliações não invasivas, incluindo perda de água transepidérmica, hidratação, elasticidade, perfusão de manchas a laser, uma biópsia de pele da parte interna do braço esquerdo (somente nas visitas de estudo 2 e 6), revisão de eventos adversos e suplemento revisão de contagem/conformidade.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Improvement in Non-invasive Skin Assessment of Skin Microperfusion
Prazo: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin microperfusion (laser speckle contrast imaging) (scale Pu). An increase in PU means improved perfusion of the skin.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Hydration
Prazo: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin hydration using the DermaLab Combo Series (unit of micro-Siemens uS), which are arbitrary. An increase in uS means improved skin hydration and improved skin barrier function.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Elasticity
Prazo: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as skin elasticity using the DermaLab Combo Series (mega Pascal mPa). An increase in mPA means worsening of skin elasticity.
14 weeks after oral supplementation
Improvement in Non-invasive Skin Assessment of Barrier Function
Prazo: 14 weeks after oral supplementation
To see the improvement in noninvasive skin assessment of objective measurements such as barrier function using Trans-Epidermal Water Loss (TEWL) using the DermaLab Combo Series (g/m2/h). An increase in these units indicates a worsening of TEWL, and reduction of the barrier function of the skin.

Prazo
Gene Chip Analysis- ITGA5 - Integrin Subunit Alpha 5
Prazo: 14 weeks

We selected 17 genes of interest, and examined the difference in their expression in each interventional arm, compared to the placebo group. The results are listed in Arbitrary Units (AU), with each AU indicating an relative increase or decrease in gene expression compared to the control (reference comparator). The range is 0.0 to 80 AU.

The gene of interest examined here is ITGA5 - Integrin Subunit Alpha 5. Gene expression values cannot be directly interpreted as indicative of better or worse outcomes. However, based on the literature review, higher expression levels of the ITGA5 are predicted to be associated with improved outcomes related to extracellular matrix production.
