An illuminated mirror will light you from the front, ensuring a shadow-free reflection - if this sounds beneficial, there are a wide range of illuminated mirrors available, and many have LED lighting, which means your well-lit reflection doesn't necessarily need to have such an impact upon the environment. Look for IP ratings when you shop for an illuminated mirror, as well. A bathroom mirror should have an IP (ingress protection) rating of 44 or above: this means that it's suitably waterproof for most areas of the bathroom, except within the bath and shower enclosure where you will need a special, watertight, IP67 or above, low voltage mirror.
