Pilot Investigation of a Multinutrient Supplement on Skin Aging and Aging Metabolites in Healthy Women

Skin antioxidant levels as well as blood metabolites may change as the human body ages1,2.
Although the chronological aging process is unstoppable, the physical signs of aging,
particularly characteristics of the skin, may be delayed through a variety of medical
interventions such as topical medications or resurfacing lasers. It is not currently known
whether skin carotenoid antioxidant levels correlate with skin aging characteristics,
although studies with other antioxidants suggest this may be true 3. In addition, while
selected blood metabolites correlate with changes in age2, we do not know if this correlates
with skin changes. Our current study focuses on whether differences in skin carotenoid levels
and blood metabolite levels correlate with skin aging characteristics in age-matched
subjects. Furthermore, we will explore whether three months consumption with a commercial
multi-nutrient formulation (LifePak Nano) affects metabolic markers of aging, skin aging
characteristics including skin elasticity and transepidermal water loss. We will also examine
whether smokers respond differently from nonsmokers in the above parameters after
supplementation.
