Inventors and scientists are going crazy anymore inventing new technology for skin care, beauty, and anti-aging. And although devices like lasers are generally used first by doctors and dermatologists in a professional office setting, eventually the technology trickles its way down to us consumers in a "do it yourself in the comfort of your own home" version.

But are these at home versions just as safe and effective as the professional ones? The answers to those questions are usually, and of course not. They aren't going to be as effective because they're almost always a toned down and weaker version of what would be used in an office setting -- think OTC versus prescription medication. But the good news is that they are generally safe for that same reason, and if you only have a mild condition that you're trying to treat then a mildly effective product might be just what you need.
