A large quantity of information shows that alpha lipoic
acid, when taken orally as a dietary supplement, has many
potential health benefits. Nevertheless, when it comes
to research on what it can do to get rid of wrinkles and
make a woman look younger, the information is at best
theoretical and (more realistically) inconclusive. While
studies of alpha lipoic acid do exist, none have been
carried out on people and none have been double-blind
or placebo-controlled to evaluate wrinkling (Source: Clinical
& Experimental Dermatology, October 2001, pages 578–582).
All of the research has been done on human dermal fibroblasts
"in vitro" in cell culture systems. In vitro
(test tube) results are always interesting, but it's not
known if they translate to human skin. These models do
mimic human skin, but something that mimics human skin
is still not the same as living skin. It is clear from
the research that alpha lipoic acid is a potent antioxidant,
but there are many potent antioxidants. Alpha lipoic acid
is not the be all and end all when it comes to your skin's
health.
