Summer is very close, and the main thing we do in summer is getting exposed to the sun, especially at the beach. Sometimes we tend to forget to use sun block, or sunscreen, and that may get us in risk of getting skin cancer.
People burn at different rates, so we all need to know what sort of sunscreen to use, and what SPF is the right type for each type of skin.
The following are guidelines to each skin type and the corresponding SPF that will protect the skin from the UV (ultraviolet) rays that cause skin cancer.
SKIN COLOR:
Albino: Tan type: none. Red sunburn with pain, swelling and peeling. SPF 50.
White: Tan type: as above. Great risk of freckles. SPF 50.
Fair: Tan type: very light after minor pink or red burns. Some risk of freckles. SPF 30.
Fair: Tan type: light. Slight risk of freckles. SPF 30.
Slightly dark: Tan type: dark. SPF 30.
Slightly dark: Tan type: dark, with less risk of sunburn. SPF 15-20.
Dark: Tan type: very dark. SPF 8-15
Black: Tan type: black. SPF 8.

I was wondering what SPF stands for? and is the factor related to the time of exposure to the sun. for example is SPF 15 for a period of 15 minutes of protection from the sun rays?
could you explain it a bit more please...
thank you
