I have pale/fair skin naturally and more so during the winter months. When we get nice weather and the sun is out I have to be careful too. However, in recent years I have taken some advice from my dad which has worked quite well.
When it starts to get hot and we get nice weather just try and get 10mins of sun a day, eventually you will start to turn brown naturally. Over the last 4-6 weeks I have gradually gone from being totally pale to slightly brown on my upper body and legs. Today for example I went for a half hour walk in the sunshine and didn't need to put anything on, I didn't get burnt. A few years back I would have got fried!
Obviously, if you're going to be out in the sun for a while make sure you cover up/sun cream/get in shade etc.
A little sun is good for you, too much can damage your skin (and make you look old)!
