Protecting your skin from the harmful ultraviolet rays of the sun has always been a major issue. Most of the aging process of our skin, pigmentation, wrinkles, etc., starts with being our over exposure to the sun. Both the UVA and UVB rays are harmful for the human skin. To counter this detrimental effect the majority of us use sun screens at a random basis.
It is always advisable to wear a sun screen lotion that counters both the UVA and UVB rays. These lotions are largely known as dual spectrum sun screen lotions. They constitute ingredients like oxybenzone and zinc oxide. While oxibenzone is used for absorbing the sun rays, zinc oxide is used to block the same but without resorting to potentially harmful chemicals.
