In order to protect the health of our skin, it is crucial to avoid sunburn now that summer has (finally) arrived, as have the long-awaited August holidays. However, let’s briefly clarify. The three types of ultraviolet rays are UVA, UVB, and UVC. UVC is inhibited by the ozone layer, whereas UVB is somewhat filtered by the atmosphere and clouds and can penetrate through glass.Since UVA rays can penetrate glass and reach our skin, they are there all year long and, regrettably, can still cause harm even in cloudy weather. They are one of the primary contributors to the creation of free radicals, which results in premature photoaging, skin sensitivity phenomena, and pigmentation issues. They even penetrate the dermis. They are essentially the ones that govern how our skin reacts with the look of a tan but are also in charge of redness and allergic reactions. UVBs are considerably stronger and can cause sunburn, but a cloudy day or a glass can both lower their severity.
However, sunshine does not just have adverse consequences; for instance, it is crucial for the production of vitamin D. Proper exposure is all that is needed to get these positive effects and, more significantly, to protect yourself.
How exactly do sunscreens function?
Physical and chemical filters are two different types that are present in sunscreens and oils. Mechanical action underlies physical filters. As a result of the presence of opaque materials like titanium dioxide and zinc oxide that work as a “mirror,” reflecting and dispersing sunlight in practice. Butyl metoxidibenzoylmethane, oxybenzone, phenylbenzelimidazole, sulphonic acid, and ethylxyl metoxicinnamate are examples of complex organic compounds found in chemical filters that absorb solar light and partially reflect it back as heat.Every one of them absorbs a particular wavelength (UvA and UvB). In contrast, ingested photoprotective chemicals, such as carrot-derived carotenoids, have an effect. They are deposited in the sebaceous glands and dermis, where they prevent oxidation reactions and neutralize the free radicals produced by UV radiation. However, they don’t take the position of filters’ function.
What does the SPF mean, furthermore?
“Sun Protection Factor” or “SPF” is the abbreviation for this term. The degree of sun protection increases as the package’s specified number rises. A product with SPF 50+ is regarded as “extremely high” sunscreen, whilst a cream with SPF 30 provides “excellent” protection.A excellent product should also provide protection from UVA rays, however this figure just indicates how well the solar device can defend against UVB aggression. Thus, the SPF measures a cream’s ability to shield our skin from UVB radiation, whilst the acronym PPD denotes protection from UVA rays. Therefore, to provide the most protection against UV radiation, a decent product should include UVB and UVA protection.
How much cream should I spread? Which cream should I choose?
It’s crucial to learn how to read product labels because, once we realized what an SPF was, we realized how critical it was to pick a sunscreen that also blocked UVA rays. A person with light skin will undoubtedly need to select a product with a high level of protection and apply it frequently. The typical amount to cover the entire body depends on the person’s weight and height, and the cream should be applied at least 30 minutes before going outside. The recommendation is to reapply sunscreen frequently and liberally to retain it, especially after sweating, after getting wet or dried out, or after getting wet or dry.Diversify is another important concept to remember. For example, you need different protection for your face than you need for the rest of your body, and you need a higher SPF if you spend a lot of time exercising in the sun. Not least, you must gradually increase the amount of time you spend in the sun’s ultraviolet rays: 40 minutes on the first day, an hour between the second and third, and up to 3–4 hours after 4-5 days. And also take care not to stay in the sun in the hottest hours.
