Cette étude démontrera la capacité du complément oral PrimaVie® à améliorer la microperfusion cutanée, l'hydratation, l'élasticité et la fonction barrière. 45 femmes seront inscrites dans 1 des 3 bras où elles recevront soit 125 mg de PrimaVie, 250 mg de PrimaVie ou un placebo (contrôle) à prendre deux fois par jour pendant 14 semaines.

Aperçu de l'étude

Description détaillée

Les sujets seront évalués en fonction de leur type de peau Fitzpatrick, seront de retour pour un total de 6 visites d'étude sur 14 semaines où les activités de recherche suivantes auront lieu tout au long de l'étude : antécédents médicaux/diététiques, les médicaments seront sera enregistrée, la randomisation du supplément basée sur l'un des trois bras aura lieu lors de la visite d'étude 1, et la distribution du produit de l'étude aura lieu à toutes les visites d'étude, l'évaluation de la tolérance du supplément, l'évaluation de l'apparence de l'investigateur et du sujet, la photographie du visage (gauche, droite et avant) seront prises, des évaluations non invasives, y compris la perte d'eau transépidermique, l'hydratation, l'élasticité, la perfusion de chatoiement laser, une biopsie cutanée de la partie supérieure interne du bras gauche (uniquement lors des visites d'étude 2 et 6), un examen des événements indésirables et un supplément comptage/examen de conformité.

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Improvement in Non-invasive Skin Assessment of Skin Microperfusion
Délai: 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
Délai: 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
Délai: 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
Délai: 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.

Délai
Gene Chip Analysis- ITGA5 - Integrin Subunit Alpha 5
Délai: 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.
