Your skin is a critically important organ. It’s also very sensitive. So how do the makers of skin care products ensure they aren’t inadvertently damaging the skin of their customers each time they introduce a new formulation?
For many years, the answer has been to test chemicals on animals before they are released for sale to humans. Yet animal testing is a controversial process that many find repugnant.
That’s why it’s good to learn of a new skin sensitization test that could do away with clinical trials on animals. Kao and Shiseido have developed a technique that enables substances to be tested in vitro, using human immune cells.
h-CLAT" is an alternative method for evaluating the skin sensitization to chemicals in an accurate and prompt manner with lower cost based on the system in which two types of proteins (CD86*3 and CD54*4 ) increase on the cell surface of the human acute monocytic leukemia cell line, THP-1.
With Europe prohibiting all animal testing for cosmetic products, we can expect further development of sophisticated in-vitro tests to ensure the safety of skin care products.

While the anatomy of the skin is the same from person to person, there are some gender differences in the physiology of our skin. But is there really a need for skin care products based on gender, and specifically something as universal as moisturizer? To answer this question, we take a look at the differences between male and female skin.

Technologies such as Intense Pulsed Light (IPL) are commonly used for wrinkle reduction, and of course there’s a place for lasers in tattoo removal. This suggests a philosophy of aggressive intervention rather than the approach we generally prefer, which is to promote homeostasis, i.e. the skin’s natural ability to maintain itself.
But it’s not quite that simple.
