Green Tea and Anti-Aging
2

• Green tea, a minimally oxidized version of tea
  made of Camellia sinensis. It originates in the
  country of China but largely associated with many
  other cultures in Asia and the Middle East.

• Extracts have been gaining popularity as key
  ingredients in skin care preparations designed to
  treat skin as an anti-aging compound. Green tea
  polyphenolic compounds have significant
  antioxidant and anti-inflammatory activities, and
  recent studies suggest that these extracts help
  mediate ultraviolet radiation damage

Does Green Tea Help as an Anti-Aging Aid?

• When evaluated, the effects of a combination
  regimen of topical and oral supplementation on
  the clinical and histologic characteristics of
  photoaging indicate that it has a net beneficial
  influence on the effects of aging.

Specific Study Results Anti-Aging Qualities

• Our primary study was done with 40 women with
  moderate "photoaging" and these women were
  randomized to either a combination regimen of 10
  green tea cream and 300 mg oral supplements
  twice-daily or a placebo regimen for 8 weeks. The
  participants of this study were carefully
  monitored and the results of their experience
  documented in an effort to learn the real effects
  on aging skin.

What Our Study Results Described

• At the end of the study when the results were
  reviewed, no significant differences in clinical
  grading were found between the treated and
  placebo groups, other than higher subjective
  scores of irritation in the treated group.

7

• Histologic grading of skin biopsies did show
  significant improvement in the elastic tissue
  content of treated specimens. Participants
  treated with a combination regimen of topical and
  oral green tea showed histologic improvement in
  elastic tissue content.
• Green tea polyphenols have been postulated to
  protect human skin from the cutaneous signs of
  photoaging, but clinically significant changes
  could not be detected.

8

• Longer supplementation may be required for
  clinically observable improvements

What Our Results Mean?

• This means that the often talked about benefits
  of green tea on the skin is not something that
  this study can validate. While the results do not
  show that a strong benefit exists they also do
  not clearly refute the possibility of a benefit.
  The only firm conclusion that can be drawn from
  this is that more studies must be done that are
  setup to measure the longer term effects.
