About this trial
This study aims to examine the connection between the level of carotenoids in the skin and a number of immune related health parameters.

Trial outcomes
Primary outcomes
Skin carotenoid levels and skin aging features
We will assess the skin carotenoid levels' correlation with skin aging features, such as wrinkles, fine lines, and age spots.
Secondary outcomes
Skin carotenoid levels and biomarkers of aging
We will assess the skin carotenoid levels' correlation with biomarkers associated with aging, such as C-reactive protein, telomere length, telomerase activity etc.
Skin carotenoid levels and self-reported perception of health
We will assess the skin carotenoid levels' correlation with self reported scores on general health and health beliefs, incidence of respiratory, gut and skin allergy symptoms, and sleep quality.
