"Anti-inflammatory agents are required in the present invention to reduce the skin irritation caused by environmental, personal hygiene, body
beautification, and dietary/personal habits situations. It is to be noted that a mixture of two or more anti-inflammatory agents, especially those
that belong to different biochemical mechanism classes, is more beneficial than corresponding equal weight amounts of a single ingredient. This
is due to various different biochemical mechanisms by which such anti-inflammatory agents provide their beneficial effect. A number of both
synthetic and natural agents have thus become available; some of such examples follow (the biochemical mechanisms of their action are
indicated in the parenthese). Ginger Root, or Zingiber Officinale Root Extract (COX-2 inhibitor), Galanga, or Alpinia Officinarum Extract (LOX-5

"The whitening effects of the flavonoid constituents of Alpinia officinarum Hance were investigated on melanin biosynthesis in B 16 mouse
melanoma cells, tyrosinase inhibition and UV absorption. The melanin content was reduced to 1.276 microg /10(5) cell for flavonoid mixture and
1.161 microg /10(5) cell for galangin while the melanin control was 1.632 microg/10(5) cell. Both flavonoid mixture and galangin reduced melanin
production with an inhibition of 21.81% and 28.86% at a concentration of 26.5 microg/mL and 29 microg/mL (107.4 microM), respectively.
Tyrosinase inhibition by the flavonoid mixture and galangin were higher at lower concentrations and galangin showed competitive inhibition at a
concentration less than 21.23 microg/mL which was soluble. In addition, the flavonoid mixture and galangin showed a broad absorption band at
270 approximately 290 nm related to the UV-B area. These observations suggest that galangin may be a whitening agent and a promising
candidate for prevention of skin cancer. This is the first full scale report on the evaluation of the whitening effect of galangin."
3. Ayurvedic anti-aging: ancient medicinal practices have many applications in modern skin care formulations.

"Galanga (Alpinia officinarum), also known as Galangal or Chinese ginger, contains essential oils, gingerols and a group of pungent substances,
diarylheptanoids. Diarylheptanoids (and analogous phenyl alkyl ketones) possess excellent anti-arthritic properties due to their arrest of
prostaglandin biosynthesis via inhibition of 5-lipoxygenase. Kaempferia galanga is easily confused with other members of the ginger family. The
medicinal and cosmetic applications of various galanga preparations include sun protection, skin whitening, anti-cancer, larvaecidal and
amebicidal, insect repellent, vasorelaxant and MAO-inhibition applications. Purified extracts of galanga, which are composed primarily of lower
alkyl cinnamate esters, have UV absorbing, (8) antioxidant and tyrosinase inhibiting properties."
