How does Sunblock works
This essay is about how sunblokck works and the correct methods to use
it. It also emphasizes the danger of the sun rays ( UVA/UVB). Many experts
have different opinions on the subject but in reality is up to us as individuals to
either use this product correctly or risk future injury on our skin.
Sunblock works by blocking the sun's UV radiation on the skin, both UVA
and UVB. Fifteen to twenty minutes before exposing yourself to the sun, it is
recomendable to apply sunblock directly on the skin. Sunblock loses
effectiveness after sweating, contact with water and after two hours of applying.
As a rule, you're supposed to time the SPF (Sun Protection Factor), which is
provided on the back of your sunblock container. This process will allow you to
know when to re-apply sunblok again.
Traditionally we use the lotions, oils, sticks, and gels. Now, the two types
of sunblock that are available to us are the physical and chemical type. Physical
sunblock is any product which carries zinc oxide and titanium dioxide. Both
ingredients protect you form UVA and UVB rays. Physical sunblock reflects the
light and UV rays off your face. This type of sunblock is better for sensitive skin.
It rarely leaves any irritaion, itching or discoloration of the skin. Chemical
sunblock has several active ingredients. There are no ingredients in the chemical
sunblock that entirely protects you from UV rays. Most chemical agents
work to protect us from UVB rays, all the while, not protecting us at all from
UVA rays which are extremely harmful to the skin.
In conclusion, taking care of your skin is very important. The results of
bad skin care could result in skin blisters, skin irritation and primarily, skin
cancer. It is always fun to be out sunbathing.
