Ladies, pick up your sunscreen lotion and you will find that there is a SPF value given on it. This may say SPF 15 or 30, depending on how strong your sunscreen lotion is. SPF stands for 'Sun Protection Factor'. The higher the SPF number, the better the protection you get when stepping out into the sun.
If you live in a cold climate area, where the sun is usually bright but not harsh, it is best to buy a sunscreen with a lower SPF. Women living in climates where the sunshine is quite harsh should invest in a higher SPF. When applying sunscreen, make sure you put on a thick coat, almost 20 to 30 minutes before you leave the shade. This way, the skin can fully absorb the sunscreen and get the protection it needs. It is also recommended to put on one layer some 30-40 minutes after you leave the shade as well.
Other than just how strong the sunscreen is, SPF can also be used to show if they lotion blocks out both UVA and UVB rays. Both of these can damage the skin and need to be kept away from the body. These are the two factors to remember during the summer when picking out a sunscreen.
