What is SPF
SPF stands for Sun Protection Factor, but it specifically indicates protection against the ultraviolet B (UVB) rays that cause sunburn. Suppose your skin starts to burn in 10 minutes under the sun without any protection. A sunscreen cream with SPF of 30 will delay it by 30 times i.e. 300 minutes. Similarly, a sunscreen cream with SPF 50 will provide 50 times more protection.
What is the difference between UVA and UVB radiation?
Sunlight has both UVA and UVB rays. Both UVA and UVB rays contribute to skin cancer and skin ageing.. UVB radiation is the main cause of sunburn and skin cancer. UVA rays, on the other hand, penetrate more deeply into the skin and apart from causing skin aging and wrinkling, are known to play a role in the development of skin cancer too. The harmful effects of UVA and UVB rays can be reduced significantly by avoiding exposure to the sun, and of course by using a good sunscreen. Both Sunstop Sunscreen Creams offer protection from both UVA and UVB radiation.
Is Sunscreen advisable only for fair-skinned people?
It is true that fair skinned people with light eyes are more vulnerable to skin damage due to UV rays from the sun. Although people with dark skin are not as high-risk as those with light skin, they develop skin cancer too and should use sunscreen as regularly as fair skinned people. Dyspigmentation (abnormal increase or decrease in the production or distribution of pigment in the skin) is also a major concern for many dark-skinned individuals, and can be minimized by regular sunscreen use.
How should Sunstop Sunscreen
be applied?
Sunstop Sunscreen should be applied one-half hour before going outside, giving the skin time to absorb it. Once you are out, the protection by Sunstop is quite likely to be broken down over time by the sun, and rubbed or washed off with sweating and water exposure. Therefore, it should be reapplied at least every two hours outdoors, and immediately after swimming or heavy sweating. At least two tablespoons of Sunstop Sunscreen is needed to cover the entire body surface.
Should Sunstop Sunscreen be used only on sunny days?
Common sense would say so, but you will be surprised to know that even on overcast days it is important to use sunscreen. The reason for that is 70-80% of the sun's rays – especially, long-spectrum UVA rays – go through clouds and fog. So the perception of clouds blocking the sunlight is often taken to mean that they are blocking the UV rays too. It is not true at all. You should use Sunstop Sunscreen every time you are out and about during day time.
