There is no doubt that the modern women (and increasingly the modern man!) is pressured by media, advertising and society to fit an idealized beauty that is achievable only with products, products and more products! Those products are crammed full of un- and under- regulated chemicals. The average American woman puts 168 chemicals on her skin every day.
Even if you are a 'health nut' about your skin care regime too you may want to do a little research. One of my favorite allies in guarding against the perils of beauty products (and champions of a chemical-free life) is Environmental Working Group's Skin Deep database of products.
