" No more lying about your age or fibbing about your sunscreen use\u2014scientists have developed  a new tool  to find out your skin&amp;#039;s real age. Developed by Taiwanese researchers, this new laser uses a burst of infrared light to look right where the epidermis (the upper layer of skin) and the dermis (the lower layer) meet. After testing the method on 52 subjects, who ranged in age from 19 to 79 years old, they were able to create a skin aging system, which could provide a standardized way to gauge the &amp;quot;true&amp;quot; age of a person&amp;#039;s skin.  Doctors could then utilize this index to monitor the overall health of a person&amp;#039;s skin over time, as well as check the effectiveness of those so-called &amp;quot;anti-aging&amp;quot; products. This new breakthrough is a reminder to always\u2014like, seriously, always\u2014 wear sunscreen. At the very least, now we won&amp;#039;t be able to pretend that we&amp;#039;ve been slathering on the SPF before hitting the beach. The laser knows all.  Want more from Natasha?
