In the world of skin care, startling antiaging and antiwrinkling
properties can be attributed to almost any plant-sourced
ingredient. One of the latest is olive oil. The concept
of olive oil having antiaging properties stems from some
evidence that diets high in olive oil may help prevent
heart disease (Sources: European Journal of Clinical Nutrition,
January 2002, pages 72–81; Lipids, November 2001, Supplemental,
pages S49–S52; Lipids, November 2001, pages 1195–1202).
There are also a small number of animal tests showing
that topically applied olive oil can protect against UVB
damage (Sources: Carcinogenesis, November 2000, pages
2085–2090; Journal of Dermatological Science, March 2000,
Supplemental, pages S45–S50).
It does seem that olive oil is a good antioxidant and
assuredly it's a good moisturizing ingredient. But research
shows similar results for other oils as well. How olive
oil's status got elevated so that it's now a showcased
ingredient in expensive skin-care products epitomizes
the caprice of the cosmetics industry.
