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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Willing and able to provide written informed consent

Age 18-30 years OR 65 years and older

Healthy individuals without uncontrolled medical conditions (over the counter inhaled and topical steroids allowed)

Fiitzpatrick I-VI (all skin types)

Disqualifiers

Pregnant or breastfeeding

uncontrolled medical conditions

Skin conditions on the upper extremity that would interfere with skin measurements of carotenoid levels such as active atopic dermatitis or psoriasis

Concurrent use of medications that affect the immune system, within 4 weeks of enrollment (eg. prednisone, biologics, methotrexate, rapamycin, prescription topical steroids, prescription inhaled steroids, others)

Trial outcomes

Primary outcomes

1

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.

Time frame
one day

Secondary outcomes

1

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.

Time frame
one day
2

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.

Time frame
2 weeks
