Why Putting on Sunblock is More Important than You Think
Sunshine is ideal for going outside and moving, but it’s important to protect your skin from the sun’s harmful rays, especially if you’re exposed to them more often than you think. Even a brief exposure to the sun’s rays can cause skin damage if you don’t wear sunscreen. The outer layers of the skin darken to block out the light, resulting in the golden tan. The best way to protect your skin from further, permanent damage is with a broad-spectrum SPF of at least 30.
Whether it’s a cloudy day or you’re going to be indoors all day, it’s possible that you’ll be tempted to stay inside. Is sunscreen still necessary? To put it succinctly, yeah!
UV (ultraviolet) rays may pass through clouds and even the windows of cars and buildings, causing harm to anyone who are exposed to them. Despite being less damaging than exposure to direct sunshine, tanning nevertheless has an adverse effect on skin ageing. Sunscreen is a must-have in your daily regimen since it’s one of the simplest and most cost-effective strategies to prevent premature ageing and skin cancer.
The effects of sun exposure on the skin
Natural defenses of the skin aren’t enough to keep you safe from the sun’s harmful rays, such when you go out for lunch in the midday heat and forget to use sunscreen.
UVA (ultraviolet A) rays accelerate the ageing process, whereas UVB (ultraviolet B) rays cause skin damage. A lack of protection can lead to long-term skin damage such as wrinkles and saggy skin as well as brown pigmentation, roughness, and darker skin.
Hypersensitivity responses to sunlight and skin cancer are more significant health issues.
Protect your skin from the sun’s harmful rays
Sunscreen protects the skin from the sun’s harmful UV rays by serving as a barrier to sunlight.
Physical and chemical sunscreens are the two basic types available. Zinc oxide and titanium dioxide are common active minerals in physical sunscreens because they reflect and scatter light. You may protect your skin from the harmful effects of the sun by using a sunscreen with an SPF of 30 or higher.
UVA and UVB rays can only penetrate skin’s outermost layers with chemical sunscreens, but physical sunscreens shield the entire body.
How much PA and SPF protection is needed?
When it comes to UVB protection, SPF (Sun Protection Factor) is a good indicator, whereas PA (UVA Protection Grade) is a better indicator.
In layman’s terms, higher SPF sunscreens shield you from UVB radiation for a longer time period. While no sunscreen can prevent 100% of the sun’s rays, SPF 30 can block up to 97% of UVB rays and SPF 50 can block up to 99%. In the long term, just 1% may make a huge difference in the health of your skin!
When it comes to UVA protection, the more + signs following PA, the better the protection. Sunscreens with PA levels of at least +++ are advised for the prevention of early ageing and skin cancer.
How do I apply sunscreen correctly?
Applying sunscreen 15 to 20 minutes before going out is a good rule of thumb. When it comes to chemical sunscreens, this is especially important since they must be absorbed into your skin before they can be effective.
Only 5 minutes are needed to apply sunscreen. Before slathering it on, make sure your skin is completely dry and then spread it liberally over your entire body. Face and neck treatments often require at least the size of a 50-cent coin in product. Including the ears, back of your hands, and the top of your feet is a good idea.
Sunscreen should be reapplied often to avoid skin damage. Reapply sunscreen every two hours, or every hour if you’re swimming or perspiring a lot, to keep your skin safe from the sun.
