What can I use to prevent this?

I tend to get a tan and my skin becomes quite dry after I go out into the sun. What can I use to prevent this?

The problem is that the sun's ultraviolet rays can be harmful for your skin when you are out in the sun for long periods of time. If you have to go out into the sun, you'd best do it armed with a good sunscreen that has a high SPF. A good sunscreen, which includes a moisturiser, will ensure that your skin stays hydrated and protected against the sun for a long time. I've heard that Kaya Skin Clinic and care has a Daily Moisturising Sunscreen that will adequately protect your skin from the sun.

Make sure the water isn't scorching hot, try using an exfoliating body wash in the shower, and moisturize after.

If that doesn't work, ask a doctor.
