Sun protection is increasingly valued, and thankfully it is! With so much information at our disposal and with the risks more evident, the need to protect our skin from solar radiation is greater and clearer. Currently, it is more than proven that unprotected exposure to the sun causes premature aging, originates or worsens spots, and can lead to some pathologies, such as skin cancer.
But which protector should I use and under what circumstances?
Almost 80% of the population's annual sun exposure time occurs on a daily basis. Therefore, this theme is not only relevant during the bathing season, but throughout the year. Also, there are various grades and types of sun protection. The best way to know which one to use is to understand each one. So let's get started!
Sun Protection Factor (SPF)
You've certainly heard of SPF 15, 30, 50, 50+...but what exactly do they mean?
These designations refer to the time a person can be exposed to the sun protected. The higher the Sun Protection Factor, the longer this time span will be. Of course, each person's skin tone also influences the amount of time they are exposed to the sun. Darker skins produce more melanin, which is a natural way of protecting the skin from the sun, so they can stay exposed longer, even with a low SPF sunscreen. For this same reason, lighter skins should always opt for a sunscreen with a higher SPF (at least SPF 30 is recommended), as it will ensure that the protection time is longer. However, depending on how often the product is applied, any protector can be indicated. The most important thing is to reapply frequently, especially after going to the water, perspiring, or wiping the body/face with a towel. For most sunscreens, it is important that the skin is dry before being applied, however, there are already options to be used on wet skin.
Physical Filters vs Chemical Filters
When it comes to the process of protecting the skin from the sun, there are two different types of ingredients that can be in the composition of the sunscreen: chemical filters and/or physical filters. The choice of filter type also depends on the needs of each skin. So, here are the main differences between them:
Physical/mineral sunscreens:
Chemical sunscreens:
Types of Sunscreens
We all have preferences, and when it comes to the type of sunscreen, it's no exception!
There are those who prefer a creamier or more liquid texture. There are also those who are a fan of dry oils. Whatever the choice, the important thing is to pay attention to the type of filters chosen, the Sun Protection Factor, and the frequency of application.
In addition to the phototype (skin color), it is also necessary to take into account the type of skin when choosing a sunscreen. For example, dry oil is not so suitable to be applied on a face that has combination or oily skin. Thus, there are different textures that can be used on the face, such as emulsion and cream, and options that can have a color or no perfume. In addition, it is very important to protect your lips and other sensitive areas such as your cheekbones.
But doesn't sunscreen prevent a tan?
The protector not only does not prevent but also helps to tan, as it allows us to avoid skin burns that can delay the process (in addition to all the other risks I have already mentioned). Healthy skin is always the best option 😊
In addition, at this stage of the pandemic, it is important to remember the need to use sunscreen on the face with the use of a mask. If we do not protect the skin, differences in skin tone may arise between the area that is exposed to the sun and the area that is protected by the mask.
If you are still not convinced of the benefits of sun protection, or if you still have any questions, please don't hesitate to contact us!
Thank you and see you in the next tip!
