I read with interest a wonderful editorial by Alla Katsnelson about the future of personalized skincare, which appeared in Nature magazine, widely considered one of the top journals in the scientific and medical community.   Katsnelson describes the myriad projects that are underway investigating the unique genetic changes in our skin’s DNA that happen as we age.  Scientists are hoping that pinpointing these genetic changes will give new information that can be used to create skincare products, think anti-aging creams or next-generation moisturizers that replenish specific proteins that you, and no one else, is missing.  I think this is all very interesting.  But although I always perk up when I come across an article about “cosmetics” in a high-profile publications, such as Nature, I am still a bit taken aback.
