I was recently traveling and whilst buying lunch, wondered why the calories of each item were not listed next to the price. Of course, I instantly realized that I wasn't in New York, where chain restaurants have been required to list calorie counts on their menus since 2008.

It got me thinking that, as consumers, we have become accustomed to having at-a-glance information about what we are putting into our mouths. When we shop for groceries, we can easily read labels to glean nutritional values and understand exactly what the product is comprised of. We should be able to do the same with something we put on our skin. Unfortunately, the rules covering cosmetic ingredients are not so rigorous, but as I explain in this video there is information to be had and it's important to read ingredients labels before you buy — even if it means donning your granny glasses in public.
