Fun in the sun – with the right sunprotection factor
The sunprotection factor (SPF)
We love the sunshine, be it on the beach or on the ski slopes. We have fun and feel good. And we protect ourselves. The sunprotection factor (SPF) is one of the things that determines the effectiveness of a sun cream. NIVEAsunprotection productsprotect the skin from UV rays, preventing us from sunburn and free radicals. As wonderful as sunbathing is, everyone is sensitive to sunlight in one way or another. There are different skin types depending on the colour of our skin, hair and eyes. As fair skin needs to have greater protection from the sun than darker skin, there is a suitable sunprotection factor for every skin type.
Important to know: The SPF that is suitable for our own skin type is determined by the amount of time the skin can protect itself. This is the period for which the skin can be exposed to the sun without getting sunburn. Depending on your skin type, location and the time of year, this is 5 to 30 minutes on average.
This formula helps you to determine the sunprotection factor that is best for you – and to choose the right sunprotection products to allow you to relax in the sun, whether you are on the beach or in the mountains.
A high sunprotection factor extends the pleasure of sunbathing and ensures you get a healthy tan. Sunprotection factors are broken down into these levels: Low (6–10), medium (15–25), high (30–50), very high (50+).
How do I find the right sunprotection factor for my skin?
The following criteria should be taken into account when choosing the correct sunprotection factor:
How long you want to stay in the sun
What skin type you have
Where you are in the sun
When you are in the sun
All-round protection: quality creams are more effective
Important: The sunprotection factor in sun creams mainly describes the UVB protection. NIVEAsun products, however, also protect you from UVA rays. The correct ratio between UVA and UVB protection is defined as recommended by the European Union. It goes without saying that this ratio is fulfilled by all NIVEAsun products.
UV FILTERS
MINERAL FILTERS
Mineral UV filters in sunprotection products are mainly made up of titanium dioxide and zinc oxide. The protection mechanism of these UV filters is based not only on absorbing sunlight but also on physical effects, namely reflecting and scattering sunlight.
CHEMICAL FILTERS
In addition, there are chemical UV filters with protection mechanisms based solely on absorbing UV radiation. In this case, the harmful UV radiation is converted into heat energy. To achieve the desired UVA/UVB protection, different UV filters are combined with each other to achieve an optimum protection spectrum. In addition to the sunprotection factor to be achieved, sensory aspects and other criteria such as water resistance also play a role in the choosing the right filters.
AVOIDING DNA DAMAGE
UVA rays do not cause any painful symptoms on the skin, but they do penetrate very deep into the cells of the dermis. They stimulate the formation of free radicals and can damage cells and the DNA in the long term. UVB rays ‘only’ penetrate into the epidermis. They are responsible for your bronzed complexion, but also for sunburn and skin cancer. As they can directly damage the DNA, they can also result in skin cancer. Using sunprotection products helps to protect us from the negative properties of UVA/UVB radiation.
