Sunscreen is important these days, but some sunscreens are better then others. This summer get yourself a good sunscreen, always have a wide brimmed hat (tightly woven one) with you. Sun protective clothing is also a good option. No matter what, you still need to put sunscreen on those parts of your body that get sun exposure.

You want a sunscreen that is a mineral screen avoid the chemical screen if you can. Mineral ingredients include zinc oxide, titanium dioxide, and avobenzone. Avobenzone is good but some people are allergic to it. If you can use avobenzone as an ingredient go for it. Stay away from sunscreens with insect repellent in it.
So, the reason you want a mineral sunscreen is because when you go out in the sun what happens? Heat! The sun causes heat and heat dilates, it will dilate your pores and then you absorb all those chemicals into your blood stream time and time again. So, stay away from a chemical sunscreen. A mineral sunscreen will do this a lot less and kind of sits on the skin and absorbs much less into skin.

Remember the skin is the largest organ of the body it does a lot of absorbing of whatever you put on it.

Ingredients to avoid:
Oxybenzone
Octinoxate
Homosalate
Retinyl palmitate
