Sun Protection

All legitimate sunscreens do the same thing, whether it's a $10.00 bottle or a $30.00 bottle. The only difference is the higher end products have more stuff added to it, such as perfumes or skin softeners.

Doctors recommend buying the less expensive sunscreens because our skin doesn't truly need all the extra stuff. The sunscreen is all that matters. In fact, when people use the expensive product, they use it scarcely, and often not enough to effectively protect their skin from the sun's UV rays. It is strongly encouraged people buy more of the less expensive sunscreen because you wont be restricted and thus can use as much as you need and sufficiently protect your skin from harmful UV rays.

Sunscreen vs Sunblock

Sunblock contains physical or inorganic ingredients that reflect and scatter the UV light and acts as a wall between your skin and the sun.

Sunscreen contains chemicals that protect your skin by absorbing and reflecting UV rays and allows a certain range of UV light to be absorbed into the skin.  

What You Eat

Also Consider your diet from protecting against the sun. For both short term (such as, preventing sun burns) and long-term (such as, preventing cancer). 

The USDA recommends we eat 7 to 13 servings of fruits and vegetables every day. Most people don't come anywhere close.

Avoid  eating greasy and fatty foods, they are very bad for the body for a number of reasons but in regards to this article it weakens your bodies defenses against the harms of UV damage. Foods that help strengthen your bodies natural defenses against sun damage are fruits and vegetables, and greatly deep green vegetables, green tea as well.
