The science behind the softgel
SOOID's formula is built around ingredients that have been studied for their role in skin, hair, and nail health. Here's an overview of the research areas behind our approach.
Supporting skin from the inside
The skin's outermost layers can be treated topically, but structural changes linked to aging — including reduced barrier function, thinning, and loss of elasticity — occur deeper. Oral supplementation allows active ingredients to reach the body's systems that support skin structure, rather than sitting on the surface.
What the research looks at
Skin barrier & hydration
Research on ceramide-type compounds has examined their relationship to skin moisture retention and barrier integrity when taken as a supplement.
Antioxidant defense
Carotenoids such as lutein, zeaxanthin, and astaxanthin have been studied for their antioxidant activity and potential role in supporting skin resilience against everyday environmental exposure.
Cellular renewal
Vitamin A is a well-established contributor to normal skin cell turnover and function, supported by decades of nutritional research.
Hair & nail strength
Biotin's contribution to the maintenance of normal hair and skin is a recognized nutritional science finding, reflected in our formulation.
Swiss-made, studied doses
Every batch is formulated in Switzerland under strict quality standards. Ingredients are included at levels consistent with published research, not simply trace amounts.
