Formula For Easy Calculation Which SP Factor Do You Need

Whether we are on the beach, in a city or on a mountain, the sun in summer makes us feel great. However, we need adequate factor protection for complete enjoyment.

It’s time to break away myths like “if I do not have factor 50, I will factor 20 with factor 30 and protection will be equally good.”

 

To not believe in such misconceptions, you must be well-informed.

 

First of all, it is important to know that the appropriate SPF factor is determined by the skin type. But also by how long you plan to expose yourself to the sun.

 

There is a calculation formula that rarely knows, and is extremely useful.

 

Before you start calculating, it’s important to know:

If your skin is bright and your hair is blond or light brown, the natural protection of your skin takes about 10 minutes.

If your skin is of medium dark complexion, and the hair is medium to dark brown, the natural protection of your skin lasts 15 minutes.

And, if your skin is dark, your hair is brown or black, the natural protection of your skin is about 20 minutes.

Therefore, if you want to calculate how much time you can spend in the sun without unwanted consequences, you need to do the following math:

Minutes according to your skin type and hair. For example, bright type – 10 minutes x The factor you have applied (SPF 30) = 300 minutes or 5 hours of safe sunbathing.

 

However, you should not forget that sunscreens are applied every 2 hours for maximum protection.

How to determine which SPF factor to use if you know how long you stay in the sun?

If you know that in the next 2 and half hours you will be exposed to the sun, or 150 minutes, for example, how to determine what factor to apply?

 

The procedure is reversed to the previous one:

 

150 minutes (the time you stay in the sun) divided by 10 minutes (ie minutes according to the type of skin) = SPF 15.

How much quantity of cream should I use?

There should be no savings here. Use whole body creams. Keep in mind that 35ml cream is enough to cover the entire human body of an adult.

 

Apply the first layer 30 minutes before sun exposure, so that the cream will have time to soak.
