While some claims have some rationale and are based on adequate research, it must be accepted that some of these claims are quite spurious with lack of adequate and extensive evidence from research before them being recommended to be used (Weiss et al., 1988).

The report that will be examined here was published in Science Daily, May 22, 2007, issue with the heading "Vitamin A Helps Reduce Wrinkles Associated With Natural Skin Aging" which states essentially that there has been research which supports a claim that local application of vitamin A to the skin apparently improves the wrinkled appearance of the skin associated with natural aging. This claim has been correlated to the findings from research that locally applied vitamin A may promote repair of these age wrinkles through production of "skin building compounds". The claims can be quoted here. ...Show more
