As summer is here we must start looking for a good sun screen, keeping your skin healthy and moisturized. If you are out in the sun for a long time it is important to wear sun screen and apply it every two hours. If you go swimming you should re-apply. Sun screen protects the skin from harmful rays of the sun that can cause many problems with skin. Although sunscreen is made to protect the skin, some brands contain harmful ingredients that can actually be bad for your skin.
