With a Sun Protection Factor of 50, the Sun Lab Express Spray aids in the prevention of sunburn. It protects your skin by helping to reduce the risk of long term skin damage and premature aging.
There are two different types of rays that affect our skin. UVA rays and UV B rays. The harsher of the two, UVB rays, attack the top layer of skin, the epidermis. The redness, swelling, pain and sometimes blistering are caused by the sun penetrating the skin and damages the blood cells, breaking them down, allowing more blood into the area. The second layer of skin, the dermis, is penetrated by UVA rays and causes premature aging. It is therefore recommended to choose a sunscreen that protects against both UVA and UVB rays.
