Let us understand more about SPF Number
SPF – SPF stands for Sun Protection Factor, which means the number in the sunscreen product indicates how long it can protect the skin against sun radiation burns.
In other words, the SPF number in a skincare sunscreen product tells you the duration it takes the UV ration from the sun to cause the redness on your when it is applied on the skin surface while you are out of your home.
For instance, SPF 30 indicate that it would take 30 times longer to burn the skin than if you were out of the home without wearing sunscreen cream or lotion.
SPF 30 allows close to 3% of UVB rays to penetrate our skin compare to SPF 50 that allows just 2% of the rays to hit the skin.
A sunscreen with higher SPF protection offer maximum protection against sun radiation and helps to avoid sunburn, UV damages and cancer compared with products with lower SPF values. But this does not mean that while you have sunscreen on your skin you can stay exposed to UV radiation for a longer duration. You should reapply the sunscreen in regular intervals and wear the clothes to cover up the skin against the sun.
