Excess sunlight increases the chance of sunburn, which is something that everyone should avoid. We all know that wearing sunscreen is the safest way to avoid getting sunburned, which is why it’s important to ensure that the sunscreen you’re using provides adequate security.
Sunburn is painful, and it can cause skin irritation, peeling, and blistering in severe cases. However, it has the potential to cause more serious harm. Skin cancer can be caused by excessive sun exposure and sunburn.
One of the most common cancers in the world is skin cancer. Each year, over 100,000 new cases of non-melanoma skin cancer are diagnosed in the United Kingdom. It is more common in older people and affects more men than women.
What to look for:
Each year, approximately 13,500 new cases of melanoma, a deadlier form of skin cancer, are diagnosed.
Skin cancer can develop anywhere on the body, with the majority of cases occurring in people under the age of 50. Melanoma kills over 2,000 people in the United Kingdom each year.
If you’re concerned about a mole, particularly if it changes and exhibits any of the symptoms mentioned above, you should see your doctor as soon as possible.
UV rays from the sun are so harmful that you can wear sunscreen even when it’s cloudy. Have we yet persuaded you to use sunscreen?
1. Does it offer UVA and UVB protection?
2. What is the sun protection factor (SPF)?
“Choosing a sunscreen is largely down to personal choice. Sunscreens are divided into mineral and chemical sunscreens, depending on their mode of action and the chemicals they contain,” Dr Laftah says.
UVA and UVB
“The sun emits two wavelengths of light that penetrate the earth’s atmosphere: ultraviolet A and ultraviolet B. Sunscreens are rated on their level of UVA and UVB protection. A broad-spectrum sunscreen with UVB and UVA protection is recommended,” Dr Laftah explains.
Since UV rays cause various types of skin damage, a sunscreen that only protects you from one form of ray won’t provide you with complete protection “At lower energy levels, VA rays have longer wavelengths. They penetrate deeper into the skin, causing collagen damage and the appearance of wrinkles and skin aging. UVB rays have shorter wavelengths and more energy than UVA rays. They damage the DNA in the skin’s outer layer, and prolonged exposure increases the risk of skin cancer.”
When the skin is damaged by light, it can cause cell mutations, which can lead to cancerous tumors. That’s why it’s critical to protect yourself from both types of UV rays.
Our recommendations for the best sunscreen
If you think one application of SPF15 is enough to protect you from the sun for an entire day outdoors, think again. SPF15 is the lowest SPF that doctors prescribe and thus provides the least defense.
The longer you spend in the heat, the more sunscreen you’ll need; reapply every two hours or after swimming or strenuous exercise.
You can also check for the star ranking in addition to the SPF rating. This indicates how well it defends against UVA rays versus UVB rays.
“The SPF rating indicates the level of ultraviolet B (UVB) protection and is rated on a scale of 2 to 50+, while the star rating refers to ultraviolet A (UVA) protection and is rated on a scale of 1 to 5, according to Dr. Laftah.”
A one-star rating indicates that the sunscreen does not provide adequate UVA protection, so look for one with a 5-star rating. In terms of SPF, something over 30 is ideal.
However, keep in mind that a low SPF sunscreen with a high star rating will not provide the same UVA protection as a high SPF sunscreen with the same star rating. This is because it is based on the UVA/UVB safety ratio. Another justification to choose a product with a higher SPF.
Dr. Laftah states, “The SPF curve represents the percentage of UVB blocked as the SPF rating increases; however, it is not linear and begins to plateau after 30.”
“With an SPF of 15, you’ll get 93 percent defense, 97 percent with SPF 30, and 98 percent with SPF 50. As a result, applying SPF 30+ 30 minutes before going outside, and reapplying every 2 hours or immediately after sweating or swimming, is recommended to help minimize the risk of sunburn. Since UVA penetrates clouds and glass, a 4- or 5-star rating is recommended for maximum safety.”
Here is another article about things that will make your skin healthy.
Dr. Laftah says that while your skin color can play a role in your natural sun protection, that doesn’t mean you shouldn’t use sunscreen when spending time in the sun.
“While people with darker skin have more natural protection, skin cancers can still occur, and the same precautions should be taken.”
According to research, black skin has a natural SPF of 13.4, compared to 3.4 for white skin. For those with darker skin, a sunscreen with an SPF of 15-30 may be appropriate.”
Not only do use-by dates apply to food, but they also apply to sunscreen. Since the minerals or chemicals in sunscreen have a shelf life, they can only protect you for so long.
“Expired sunscreens are less likely to provide sufficient protection, increasing the risk of sunburn and possibly causing skin irritation,” says Dr. Laftah.
Now that you’ve learned what to look for in sunscreen, you may be curious about the ingredients used in the creams.
Mineral and chemical creams are the two types of sunscreens, according to Dr. Laftah.
“The mineral (physical) sunscreens contain titanium dioxide and zinc oxide, which deflect and disperse UV rays like tiny mirrors, preventing them from penetrating the skin,” she explains.
“They have a white cast that may detract from their appeal; however, they are less likely to irritate the skin and may be preferable for those with sensitive skin, such as eczema and rosacea.” Chemical sunscreens contain ingredients that are absorbed by the skin, such as oxybenzone, avobenzone, octinoxate, octocrylene, octisalate, and homosalate.” They protect the skin from UV damage by absorbing UV rays and converting them to heat before releasing the heat. Since they don’t leave a white cast, they’re ideal for people with darker skin. They also have a lighter texture, making them ideal for oily or blemish-prone skin.”
