Natural conditions are still in transition from dry to rainy season, making the temperature rise during the day up to 5 degrees centigrade. Do not ignore the scorching heat of the sun at noon, UVA and UVB rays emitted during the day tend to be able to cause skin cancer. Perform preventive measures by using a sunscreen or sun block. However, which type is suitable for you and your activities?
You must already know the dangers posed by ultraviolet (UV) A and B in sunlight. Besides can cause wrinkles, UV rays can also cause skin cancer. So, it’s important for you to choose the right sunscreen for skin protection.
Several years ago, people chose sunscreen only by see the content of sun protection factor (SPF), where the SPF is only able to ward off one type of light, namely UVB rays. "SPF can only ward off UVB rays," said David J. Leffell, MD, professor of dermatology at Yale School of Medicine, Connecticut, United States.
Recent research shows that UVA rays also increase the risk of skin cancer. Only UVA rays do not cause sunburn but can penetrate deeply into skin and cause wrinkles.
An environmental protection agency in the United States estimates that more than 90% of skin changes associated with changes in age is caused by exposure to UVA rays lifetime.
So, which sunscreen is right for you? Of course you'll want a sunscreen for both sun rays. There is a sunscreen that contains spectrum protection which includes the content of benzophenones (oxybenzone), cinnamates (octylmethylcinnamate and cinoxate), sulisobenzone, salicylates, titanium dioxide, zinc oxide, avobenzone (Parsol 1789) danecamsule (Mexoryl SX).
SPF 15 and above for UVB protection
SPF indicates the effectiveness of sunscreens in preventing skin inflammation caused by UVB rays. For most people, SPF 15 is enough. But people with white skin, people with a history of skin cancer in their families, or some conditions like lupus, can increase sensitivity to sunlight that requires a level of protection with an SPF of 30 or more.
Maybe in your mind, SPF 30 protects two times that of the SPF 15. While SPF 15 filters out 93% of UVB, SPF 30 filters out 97%. Just a little different, isn’t it?
UVA Protection
There is no specific level that says how much sunscreen is used to counteract UVA rays. So when you need a UVA protection, you need to pay attention to composition.
Find a sunscreen that contains at least ecamsule, avobenzone, oxybenzone, titanium dioxide, sulisobenzone, or zinc oxide.
Waterproof sunscreen
If you want to travel or to go swimming, use a waterproof sunscreen (including your sweat).
PTA Board America explaining waterproof sunscreen means SPF level remains effective for 40 minutes in the water. Waterproof sunscreen with a powerful level means it can hold for 80 minutes when you're in the water for swimming. So, if you will swim more than that you need to rub sunscreen before returning back into the water.
Select the brand you prefer
Although experts recommend one brand of sunscreen, but you do not like it, you're not going to use it. Use sunscreen that you like and are suitable for your skin.
Sunscreen Safe for Children
Children and babies have sensitive skin, especially when using adult products. So, avoid sunscreens with para-aminobenzoic acid (PABA) and benzephenones like dioxybenzone, oxybenzoneatau sulisobenzone. Sunscreen for kids tends to use the composition that does not cause irritation to the skin, such as titanium dioxide and zinc dioxide.
For babies 6 months upwards, choose a sunscreen that is designed specifically for children with an SPF of 15 or more. However, it is recommended to you, keep babies under 6 months of sunshine.
Sunscreen for sensitive skin or allergies
People with skin conditions such as rosacea (redness and scaly skin) may be better off using sunscreens designed for children. Use a sunscreen that contains titanium dioxide or zinc oxide instead of chemicals such as para-aminobenzoic acid (PABA), dioxybenzone, oxybenzone, or sulisobenzone.
If you have irritated skin and allergy, avoid sunscreens that contain alcohol, fragrances or preservatives.
