FOLLOWING THE BLUEPRINT Knowing one's specific genetic tendencies can determine the skincare products, nutrition and supplementation needed to stabilize skin health and prevent issues. called mitosis, and the resulting "daughter" cells contain the same number and type of chromosomes as do their parent cells. The health of those cells can be protected as well. Additionally, like plastic tips on shoelaces, there are regions of repetitive DNA at the end of each chromo- some called telomeres. The telomere protects the chromosome and helps determine how many times a cell will divide. So the telomere itself needs protection. "If DNA blueprinting is in-depth, it will be able to access the state of the telomeres, which are what project the longevity of the cells," says Kris Campbell, CEO of skincare manufacturer Tecniche (tecniche.com). "This, in turn, can indicate the grade of therapeutic skincare products required to offer cells maximum protection." Imagine being able to observe, and then re-observe, skin health at the DNA level! "It would be helpful to have a baseline," notes Steinhouser, "to be able to follow and use products that prevent skin health issues from becoming problematic." Predicting Skin Response What is more important to DNA skincare research than what someone's genetic make-up reveals, is how those genes behave. "DNA blueprinting may tell us how a person's skin responds. For instance, a person with a particular type of melanin gene may be more susceptible to getting sunburned," says Jay Tiesman, Ph.D., principal scientist at Proctor & Gamble (pg.com). "However, just like a blueprint doesn't tell you how well a house is built, the DNA blueprint can only tell what genes you have, not how they work. This is why we study gene expression, which tells us how your DNA responds when your skin is exposed to the environment. This gives us much more power than simply looking at the DNA blueprint alone." Additional methods of studying gene performance are leading to a better understanding of skin needs. "One of the most important technologies in the genomics toolbox is the gene chip," says Karen Asquith, director of education at G.M. Collin Skincare (gmcollin.com). A gene chip is a postagestamp-sized, glass device that scientists use in genetic testing. "This allows us to determine which genes are turned on and up—or turned off and down— in response to different biological conditions," Asquith continues. "Epigenetics is the study of how the epigenome, a set of chemical compounds that sits on top of the genome, turns the gene on or off with the influence of our lifestyle, diet and environment." dayspamagazine.com/freeinfo • Use FreeInfo #37 84 DAYSPA | JUNE 2013
