I have just stumbled upon this great new tool were you can monitor your skin. It's called skinfoto and it's a mobile app. For example; if you have acne or a scar you are treating and want to monitor it's progress, you can upload a photo of the area you are treating and see how it improves over time. I have sun damage on my face, so I am using this app to watch my skin change. Here is the website http://www.skinfoto.com/. If anyone else starts using it let me know and we can compare notes!
