What do the different SPF values ​​mean?

SPF is short for sun protection factor, which means the amount of time a sunscreen will protect your skin from UV rays.
The higher the SPF, the longer the protection will last.
There is a misconception that these are coverage density numbers, or that they show how many times the product increases the skin’s natural protection against the sun’s rays.
In fact, these numbers are time indicators that are accepted in cosmetics.
The SPF number tells you how long it may take you to burn after applying it, compared to using no protection at all.

As an example: If you can spend 20 minutes in sunlight without burning, an SPF20 lotion/oil will multiply that “self-protection time” by 10, which equals 200 minutes.
It should be borne in mind that these are theoretical indicators.
SPF 50 provides approximately 98% protection from UVB rays, while SPF 30 provides approximately 96.7%. Protection levels above SPF 50 provide only marginal additional protection, and no SPF level can provide 100% protection. In most situations, SPF 30 is sufficient protection provided it is applied correctly – SPF 50 remains the safer option for preventing sun damage.

The time for which a product will protect us depends on heat, staying in water, perspiration and the strength of ultraviolet rays.
That is why it is important to renew our sun protection every 2 hours and pay attention to the needs of our skin.
Give your skin time. Because with a higher sun protection factor, you tan more slowly but permanently.
Fortunately, the days when we exposed ourselves directly to the sun without using cream, and for a long time “to tan faster”, are long gone.
Today we know a lot more about sun protection and the risks of sun exposure.
