Protect children. Children are particularly vulnerable to the effects of UV radiation and often spend more time outdoors than adults. Parents should take special care to protect them from the sun using protective clothing, hats, sunglasses and sunscreen. Keep babies and young children out of direct sunlight. Quite the reverse is true. Although your skin changes colour more slowly when you're wearing sunscreen, the resulting tan will be better and longer-lasting because the sunscreen will prevent your skin from burning and peeling. Some PIZ BUIN ® products even contain special ingredients that stimulate the natural production and the even distribution of tanning pigments in the skin. For over 70 years, PIZ BUIN ® has been providing sun lovers everywhere with suncare solutions that help them achieve the perfect balance between getting a beautiful tan and the protection they need. In fact, PIZ BUIN ® was one of the first to make tanning safer by implementing the Sun Protection Factor (SPF) system in the 1960s. So wherever there’s sun, whether it’s at the beach, on a mountain or in the city, PIZ BUIN ® has been there helping people to enjoy life in the sun, safely.
A sunscreen with broad-spectrum protection means it has the ability to protect against the harmful effects of both UVA (ageing rays) and UVB (burning rays). To be classified as offering broad-spectrum protection, a sunscreen product needs to absorb or reflect at least 90% of the UV rays from the 290 to 400 nanometres (nm) wavelength range. Overexposure to the sun can threaten your health, so avoid staying out in the sun too long, even when using a sunscreen. The SPF number indicates how many times longer you can stay in the sun before starting to burn. The way it works is that you take the number of minutes it normally takes your skin to burn in the sun with no protection (let's say 15 minutes). Then, you multiply that number by the SPF number (in this case, Factor 6). Since 15 x 6 = 90, you should have 90 minutes before you start to get a sun burn. In other words, the higher the SPF the greater the protection of your sunscreen. But remember these are theoretical values. In reality, the time depends, among other factors, on your skin phototype and the local UV intensity. It's important that your sunscreen is water resistant when you go swimming because UV radiation half a metre below the surface of water is still 40% as intense as it is on the surface. You also need to protect the part of your body that's above the surface, as water reflects some 25% of UV radiation and can intensify the harmful effects.
A "photostable" sunscreen is able to withstand the effects of UV exposure better, so it keeps its level of protection.
UVA and UVB radiation are familiar terms, but what do they mean and how do they affect us? Find out here. + Different skin types react to the sun in different ways, so the type of skin you have influences how long you can stay in the sun and what types of sunscreen you need.
How long does sunscreen last before it goes out of date?
To protect the skin, sunscreen uses UV filters that absorb radiation from the sun. When a sunscreen is exposed to this radiation, it can alter the chemical structure of the UV filters, thus degrading their protective capabilities. The key technology used in any sunscreen is the UV filter. UV filters can be either chemical or physical. The sun makes life on earth possible, but it can also have harmful effects — especially without sufficient sun protection. Going on holiday often means exposing your skin to the sun for the first time after a long winter of cold weather and warm clothes. It's important to devote extra attention to your skin before you leave to make sure it is ready for the sudden change.
If you do end up overdoing it in the sun, do not fear! A cooling aftersun will work to relieve any inflammation and help to heal your sunburn. From your favourite suncare brands like Malibu and Nivea, Savers have a range of aftersun products with skin hydrating ingredients such as aloe vera and avocado oil that’ll help to soothe and nourish burnt skin. You can decrease your protection level step-by-step during your holiday as soon as your skin has produced its own defence system: the tan. After a few days of effective protection, try moving from a high protection product to a medium one. But remember that people with a natural suntan also need to apply sunscreen as a tan does not provide sufficient protection from UV exposure. Also bear in mind, that the SPF level you need largely depends on your skin phototype and the local UV intensity. Ultraviolet (UV) rays are invisible and are divided into UVA, UVB and UVC rays. UVA rays cause long-term skin damage, including skin cancer and premature skin ageing, while UVB rays are the main cause of sunburn. Approximately 10 times more UVA rays reach the earth's surface than UVB rays. UVC rays are absorbed by the earth's atmosphere and don't affect the skin.Almost all* PIZ BUIN ® sun protection products range from being water resistant to extra water resistant like our PIZ BUIN WET SKIN ® Transparent Sun Spray. The first colour-related effect of exposure to the sun is known as "immediate pigmentation", or a colouring that appears during exposure and disappears within 2 hours. Caused by UVA and visible light, immediate pigmentation does not protect against sunburn. Chemical filters work by absorbing UV light and converting it to higher wavelength rays that are less harmful to the skin. PIZ BUIN ® suncare products give you the sun protection you need, but what else can you do to ensure the best possible safety under the sun? +
