Sunscreens decoded

                                 Here's some no nonsense facts about sunscreens.....

Why are sun rays harmful?

The Sun’s rays are a blessing. They bring light and help plants produce food and energy. However, certain rays of the sun are harmful for the skin.

UVA Rays – Also called ageing rays increase the rate of ageing.  UVA rays account for up to 95 percent of the UV radiation reaching the Earth's surface. They can penetrate clouds and glass. UVA has long been known to play a major part in skin aging and wrinkling (photoaging).

UVB Rays – Also called burnig rays is the chief cause of skin reddening and sunburn, tends to damage the skin's more superficial epidermal layers. It plays a key role in the development of skin cancer and a contributory role in tanning and photoaging.

What are Sunscreens?

Sunscreens are products combining several ingredients that help prevent the UVA and UVB rays from reaching the skin.

What is SPF?

Sun Protection Factor. It is the percentage of harmful rays blocked by the sunscreen.  SPF 15 filters out approximately 93 percent of all incoming UVB rays. SPF 30 keeps out 97 percent and SPF 50 keeps out 98 percent. They may seem like negligible differences, but if you are light-sensitive, or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.

What SPF suits me best?

It depends on how much exposure you have to the sun. SPF 15 or higher must be used for very little exposure or for people working indoors. The higher the exposure, go for the higher SPF.
