A lot of people dream of getting this golden tan, so they rush to get sun tan lotions, creams, sprays….. etc. without even knowing the difference between SPF and UV!
Ultra Violet Index is a scientific term used to tell us how many UV rays reaches earth at different times throughout the day. Those rays are always present but not visible and consists of both; UVA and UVB. The UVB is a good source Vitamin D3.
When looking at the scale of the UV index know that the higher the number, the stronger the rays are and the more exposure you will get! When the index is at a high number you have to be careful for that it wont take very long to burn your skin... just keep in mind when tanning at this time; "how pretty is your red tan with the peel effect" ewe!
The Sun Protection Factor is the number you see on the bottle. The higher the number, the higher the protection you get. How to decide which number you need is based on your skin and how fast you normally burn. If you tan easily under the sand without a burn, you can use 4 and above...
On one hand, sunscreens usually come in the form of a lotion or cream, and has an SPF rating. When applied it reacts with the sun creating an invisible barrier. It is better to apply it 20 minutes prior to sun exposure and swimming, and reapply when you come out of the water. There are some waterproof sunscreens that last longer than the regular ones.
Enjoy the sun..... safely ;-)
