When it comes to sun protection, there are a lot of factors that you need to take into consideration. Sunblock is not just for people who live in sunny climates – everyone should be wearing sunblock because the UV rays can damage your skin no matter where you live. This blog post will teach you about what SPF and PA are, and why EGF (epidermal growth factors) is important for healthy skin, and more!
What are SPF and PA ratings?
SPF stands for Sun Protection Factor. It's a measurement of how well the sunscreen protects your skin from the sun's harmful rays. The higher the SPF, the better protection you get from UVB and UVA rays.
The SPF rating is a measurement of how long you can stay outside during the day and be protected from the sun’s burn-causing UVB rays. You should, however, also look for PA+ on your sunscreen bottle—this means it has high protection against UVA as well. The letters “PA” followed by plus signs (PA+, PA++, etc.) represent different levels of UVA protection offered in Japan to help consumers find products that fit their needs best!
What does SPF value indicate?
The SPF value indicates the level of sunburn protection provided by the sunscreen product. All sunscreens must be tested according to an SPF test procedure. The test measures the amount of ultraviolet (UV) radiation exposure it takes to cause sunburn when a person is using the sunscreen in comparison to how much UV exposure it takes to cause a sunburn when they do not use the product. The sunscreen is then labeled with the appropriate SPF value indicating the amount of sunburn protection provided by the product. Higher SPF values (up to 50) provide greater sunburn protection. Because SPF values are determined from a test that measures protection against sunburn caused by ultraviolet B (UVB) radiation, SPF values only indicate a sunscreen's UVB protection.
Difference between UVB and UVA.
A lot of people don't realize this but there are two types of ultraviolet radiation: UVB which causes burning or reddening skin when exposed too much over time; and less harmful stuff called UVA with no immediate effect like redness.
How to reduce sun damage.
Spending time in the sun increases a person's risk of skin cancer and early skin aging. To reduce these risks, consumers should regularly use a Broad Spectrum sunscreen with an SPF value of 15 or higher in combination with other protective measures such as:
- Limiting time in the sun, especially between the hours of 10 AM and 2 PM when the sun's rays are the strongest.
- Wearing clothing to cover skin exposed to the sun (long-sleeved shirts, pants, sunglasses, and broad-brimmed hats) when possible.
- Using a water-resistant sunscreen if swimming or sweating.
- Reapplying sunscreen, even if it is labeled as water-resistant, at least every 2 hours. (Water-resistant sunscreens should be reapplied more often after swimming or sweating, according to the directions on the label.)
Consumers should also be aware that no sunscreens are "waterproof" because all sunscreens eventually wash off. Sunscreens can only be labeled as "water-resistant" if they are tested according to the required SPF test procedure. Sunscreens labeled "water-resistant" sunscreens will also be required to state whether the sunscreen remains effective for 40 minutes or 80 minutes when swimming or sweating, and all sunscreens will be required to provide directions on when to reapply.
