The Effect of a Healthy Snack on Radiance, Aging and Inflammation of the Skin

Completed · Not applicable

Conditions studied: Skin Laxity

In brief

The anti-oxidative and anti-inflammatory effects of polyphenolic compounds of almonds have been reported in limited animal studies and may have the potential to improve skin radiance. However, the skin related beneficial properties of almonds have not been investigated in humans. This study will examine the effects of almond consumption on human skin radiance in Asian women as a pilot.
