The sun<\/b> is a source of remarkable benefits for both our skin and our body. Solar radiation in contact with the skin is an excellent ally for physical well-being and also promotes the production of vitamin D and melanin.<\/p>\r\n\r\n\r\n\r\n
However, prolonged and careless exposure to the sun can cause serious damage to our skin, such as erythema, sunburn, premature skin aging, and sunspots.<\/p>\r\n\r\n\r\n\r\n
There are, however, a series of precautions and habits that allow you to safely enjoy the benefits of the sun<\/b>. These are a few guidelines<\/b> for proper and safe sun exposure<\/b>.<\/p>\r\n\r\n\r\n\r\nWhich Sunscreen Should You Choose?<\/h1>\r\n\r\n\r\n\r\n
The first rule \u2014 and certainly the best known \u2014 is without any doubt to apply sunscreen<\/b><\/i>. But which one? There are many types, formulas, and textures available on the market. What matters most, however, are the SPF and the fragrance.<\/p>\r\n\r\n\r\n\r\nSPF 30, 50 and 50+: What\u2019s the Difference?<\/h2>\r\n\r\n\r\n\r\n
SPF<\/b> (Sun Protection Factor<\/b>) is the numerical scale ranging from 6 to 50+ that provides information about the product\u2019s ability to protect against UVB rays<\/b>, the most harmful and carcinogenic rays.<\/p>\r\n\r\n\r\n\r\n
For proper sun exposure, it is recommended to always apply a sunscreen with a protection factor no lower than 30, as it is capable of blocking approximately 97% of UVB rays<\/b>. A SPF 50<\/b>, on the other hand, blocks more than 98% of UVB rays<\/b> and is therefore more suitable for preventing skin damage, especially in people with very fair and more sensitive skin.<\/p>\r\n\r\n\r\n\r\n
Unlike SPF 50 sunscreen, which indicates an SPF between 50 and 59.9, the Very High Protection 50+<\/b> indicates an SPF of 60. This does not make it a \u201ctotal protection,\u201d since beyond SPF 60 there is no proven significantly higher protection.<\/p>\r\n\r\n\r\n\r\n
There is no true numerical factor for UVA rays<\/b>, which are the rays that penetrate deeper into the skin and cause long-term damage such as sunspots, dryness, and loss of elasticity.<\/p>\r\n\r\n\r\n\r\n
For this reason, the European Commission introduced \u201cbroad-spectrum\u201d products<\/b>, equipped with filters that protect simultaneously against both UVA and UVB rays.<\/p>\r\n\r\n\r\n\r\nSPF 50+ and SPF 100: What\u2019s the Difference?<\/h2>\r\n\r\n\r\n\r\n
And what about SPF 100 sunscreen<\/b>? Just like SPF 50+, SPF 100 sunscreen<\/b> does not guarantee total protection. For this reason, the European Commission recommended that SPF values higher than 50+ should not be indicated on product packaging, as excessively high values may mislead consumers.<\/p>\r\n\r\n\r\n\r\n
If we refer exclusively to UVB rays<\/b>, there is no real difference between SPF 50+ and SPF 100 protection.<\/p>\r\n\r\n\r\n\r\nHow Much Sunscreen Should You Apply?<\/h1>\r\n\r\n\r\n\r\n
The answer to this question is the Finger Tip Unit<\/b> (FTU<\/b>), literally the fingertip measurement unit<\/i>!<\/p>\r\n\r\n\r\n\r\n
This type of measurement is an effective method for understanding how much sunscreen should be applied to different areas of the body. One FTU corresponds to a \u201cstripe\u201d of product placed on the index finger, more precisely on the last phalanx. Naturally, the larger the body area, the greater the amount of cream required.<\/p>\r\n\r\n\r\n\r\n
For example: 1 FTU corresponds to approximately 0.5 g of product and is sufficient for application on your hands<\/strong>.<\/p>\r\n\r\n\r\n\r\n To protect larger areas, such as the arms<\/strong>, 3 FTUs are needed for each arm.<\/p>\r\n\r\n\r\n\r\n For one leg<\/strong>, 6 FTUs are required; for the face<\/strong> and neck<\/strong>, 2.5 FTUs; and finally, for larger areas such as the back<\/strong>, chest<\/strong>, and shoulders<\/strong>, approximately 14 FTUs are needed.<\/p>\r\n\r\n\r\n\r\n In addition to using a sunscreen with adequate SPF, there are also several precautions we should keep in mind when exposing ourselves to sunlight.<\/p>\r\n\r\n\r\n\r\n A good precaution is to limit sun exposure<\/b> during the hottest hours of the day and avoid staying in the sun for excessively long periods. In general, it is recommended to sunbathe for no more than 20\u201330 minutes<\/b> per day and to avoid exposure between 12 PM and 4 PM. Any sunscreen should be applied at least 30 minutes before<\/b> sun exposure, reapplied at regular intervals every 2 hours<\/b>, and especially after every swim<\/b>.<\/p>\r\n\r\n\r\n\r\n Even simple outdoor activities expose our skin to the sun\u2019s rays. For this reason, sunscreen should also be applied before long walks, exercise, or outdoor work.<\/p>\r\n\r\n\r\n\r\n If you are among those who love the blonde highlights<\/b> your hair develops during summer holidays, be careful! Those highlights are actually real sun damage<\/b>! Prolonged sun exposure can weaken both the hair and scalp and, particularly in predisposed individuals and men, may over time contribute to early hair thinning or baldness.<\/p>\r\n\r\n\r\n\r\n You certainly will not start losing your hair simply by going to the beach, but we recommend protecting even those areas that are usually considered low-risk or less exposed to the sun. The nape of the neck is one of those areas and should therefore be protected with a hat, while hair lengths should be shielded using products containing SPF.<\/p>\r\n\r\n\r\n\r\n Finally, we recommend using sunscreens free from deodorants or fragrances<\/b>, as they may contain chemical agents responsible for photosensitivity (spots!) or allergies, and may interfere with the effectiveness of the protection, preventing it from guaranteeing the same SPF level.<\/p>\r\n","protected":false},"excerpt":{"rendered":" Il sole rappresenta una fonte di notevoli benefici per la nostra pelle e il nostro organismo.
