a skin cream that is chosen on the basis of; gender, age, body area, how old your skin looks and how old you want your skin to look.
This is a purely superficial l treatment, mainly for superficial people who would buy it even if it was only an advertising gimmick, witch it is not.
a 60 year old woman might want the skin, between the wrinkles, on her face to look like that of a 20 year old woman. This cream would contain the micro-flora from the face of a 20 year old woman, plus all of the goodness of a 20 year olds sweat
The micro-flora will be selected stains, grown in a lab. And the sweat will be a cocktail of; fats, salt, hormones, etc. everything that these bacteria need to flourish.
There are three underlying assumption behind this idea
a] That a persons body chemistry, hormone levels etc changes with age.
b] That the part of those changes the is expressed in sweat will change the micro-floral population.
c] That the appearance of this microscopically thin layer of living skin will have a noticeable effect on the apparent age of the skin beneath it.
Ideally the cosmetics companies looking to sell pro-biotic skin creams can be harnessed to do some good, and help to fund round two of the Human Microbiome Project.
