The beauty industry is, like many industries, rife with both innovation and the mere appearance of it. There is rarely anything new under the sun, and some brands try to create complex, incredibly expensive electronic devices to do what good products and a bit of effort – or a knowledgeable facialist – can do more cheaply. I often find that it is the simplest tools, and not the fancy ones costing hundreds, which make a pragmatic difference to everyday life.
