UVA rays are responsible tanning, skin aging and wrinkles whereas UVB rays are responsible for sunburn and developing cancer. A sunscreen consists of both inorganic and organic components.

  • WHY IT IS NECESSARY TO USE SUNSCREEN?

The reasons to use sunscreen are as follows:

  • PREVENTS SUN BURN:

Sun burn is caused by over exposure to the sun. It is the sign that the DNA of the skin is damaged by the excessive heat. This sun burn can be responsible for increasing the chances of skin cancer as it is said that having sun burn after every two years can increase the chance of having cancer by three times. So instead of having regrets later it is suggested to shield your skin from sun through sunscreen.

 

  • PREVENTS TANNING:

Some people do not get sun burn which is good but on the other hand they get tan. This tanning on regular basis can result in pre-mature aging, wrinkles, saggy skin and dull complexion. This tanning also leads to discoloration and cancer. Sun screen prevents tanning but does not completely cure it.

  • PROTECTS AGAINST CANCER:

Most of the skin cancers are caused by tanning beds and Ultra Violet rays. The long-term or short-term exposure to the sun leads to sun burn and damage of the skin DNA which later have potential to transform into cancer. However, sunscreen does not eliminate the risk of cancer but can only prevent it.

  • PREVENTS REDNESS AND IRRITATE PATCHES:

Polymorphous light eruption (PLE), is a common allergic reaction caused by sunlight. PLE is not same as the sunburn it arises to the people whose skin is extremely sensitive to the sunlight. It is in the form of itchy rash. To protect the skin from PLE it necessary to avoid sun exposure as much as possible. To reduce the causes of eruption generously apply the sunscreen on your face, neck, hands and shoulders.

  • MAKES SKIN HEALTHY:

The penetration tendency of UVA rays is more than the UVB rays. Since the UVA rays penetrate deep into the skin so they are responsible for destroying a structural component called collagen. As collagen degrades the skin loses its elasticity and smoothness causing wrinkles and fine lines. To limit the penetration of UVA rays it is suggested to put sunscreen on before heading out.
