Do you know how the sun protection factor works? Here's what you need to consider when choosing the perfect sunscreen for you.
Beach, sun, sea, sand, umbrella, magazine, towel, a couple of dips... sounds good, doesn't it? That's the thing about summer, it cheers up your spirits and makes you want to put on your swimming costume and go out and toast yourself like a good slice of bread.
But beware, it is precisely at that moment that we must be armed to the teeth against our worst enemy: UV or ultraviolet rays. And there is nothing better than a good sunscreen to reduce the impact of the sun's harmful rays on our skin.
There is, however, one very common nuance, and that is that not everyone has a good understanding of how sun protection factor or SPF works. As a tip, it is not enough to apply sun lotion just once. On the contrary, it is advisable to always have the bottle to hand, especially if you are constantly in the water and, above all, because sweat also helps to remove the layer of protection from your skin.
To help you learn how to protect your skin properly from UV rays and choose the best protection factor for you, we bring you below everything you need to know about what SPF is and how it works. You're sure to get it right and your skin shield will be unbeatable.
What is the sun protection factor?
The sun protection factor (SPF) is a number that appears on all sun creams and lotions. This number indicates the maximum time you can be exposed to the sun without getting sunburnt once you have applied the sunscreen.
So, no, it's not that the more you have, the more protection you have, it's that the higher the number, the longer you can stay in the sun without damaging your skin..
How can you calculate the right sun protection factor for you?
Easy, before answering this question you must answer another one: approximately how long can your skin withstand the sun without getting sunburnt and without any protection?
This varies depending on your skin type or, in other words, your phototype and your ability to absorb the sun's rays over a prolonged period of time. Obviously, someone with fair skin will withstand much less exposure than someone with darker skin (to a certain degree).
To calculate the perfect sun protection factor for you, all you need to do is a simple mathematical operationwhich is multiplying the time (in minutes) your skin can stand the sun by the protection factor of the lotion you are going to use.
For example, if you are one of the lucky ones who can stand half an hour in the sun like a titan and the sunscreen you have on hand is factor 30, you only have to multiply 30 minutes by 30 of the sun factor.
However, there is a small nuanceThis time is altered by bathing, excessive sweating, exposure at the most dangerous hours (the closer to midday, the more aggressive the rays are), friction with clothing and the place where you are.
Experts generally recommend no more than two hours of continuous sun exposure. and, in case of any factor that alters the protection, reapply cream immediately.
UVA and UVB: the ultraviolet rays that affect your skin
A very important element to look out for when buying your sunscreen or lotion is the type of protection it offers.
In that sense, most creams will offer protection from two types of rays:
- UVA rays are the most relentless, but also the ones we notice the least in our daily lives. They represent 95% of the ultraviolet rays that touch the surface of our planet. They pass through everything: clouds, glass and the epidermis. They do not cause pain, but penetrate very deep into the skin and are responsible for premature ageing, pigmentation disorders or sun intolerance.
- UVB rays are the painful onesThe ones you notice after prolonged exposure of your skin. Although they make up the remaining 5% of the UV rays that reach the planet, they are the ones that most intensely alter your pigmentation and melatonin, which is responsible for your tan. They can pass through clouds or glass, but they penetrate more aggressively into the dermis and are the cause of sunburn and allergies, as well as actively promoting skin cancer.
So before you buy your sunscreen, make sure it offers both types of protection.
