It is important for us to protect our skin from the Sun. We should be worry about the harmful effects of the sunlight that can damage our skin. Without protection, our skin will be penetrated by two types of ultraviolet radiation from the sun. It can burn, redden our skin, and even can cause skin cancer. So how should we protect our skin from damage? There are two products; sunblock and sunscreen. Many people assume that these two are the same, whereas they are not. Sunblock and sunscreen actually work in different ways. By knowing the differences, it can help you to decide which is best to protect your skin. It is worth to note that you should apply sunblock and sunscreen every day before leaving the house, even during rainy days! Whenever there is sunshine, you must apply even a thin layer of sunblock or sunscreen. Now, there are several terms that you need to understand in order to know the differences between sunblock and sunscreen.
Sunblock acts as a physical barrier between your skin and the Sun’s harmful rays. Sunblock is quite thicker than sunscreen, which creates a film or layer on the skin that the Sun’s UV rays cannot pass through. It contains active ingredients, organic and non-organic.
Sunscreen works as a chemical barrier to protect your skin from the Sun. Sunscreen does not block UV rays from the Sun, but it absorbs most of the rays before it get to your skin. Sunscreen ‘screens’ the UV rays and reverses any harmful effects from it.
UVA and UVB
UVA and UVB are the two types of ultraviolet radiation from the Sun. It can cause different harmful effects to our skin. UVA rays can cause premature aging through excessive sunlight exposure such as wrinkles, sagging and photo aging. On the other hand, UVB can burn and redden your skin. Both rays can lead to skin cancer, which makes it so important to apply sunblock or sunscreen when you are outside.
SPF stands for Sun Protection Factor. It roughly estimates the duration of sunblock or sunscreen’s ability to protect your skin from the UV rays. It can be calculated by multiplying the amount of time taken for your skin to burn after sun exposure. For example, a sunblock or sunscreen with SPF 30can prevent your skin from burning for 150 minutes (SPF 15 x 10 minutes = 150 minutes (2 hours 30 minutes). It indicates that the higher the SPF is, the longer the product can protect your skin.
Pros and cons of sunblock
Sunblock is more beneficial and effective for preventing sunburns and suitable for outdoor activities under the intense sun exposure. If you are planning for a swim at the beach, you can find water-resistant sunblock so it would not be washed off by the water. With higher SPF, you do not have to keep reapplying it as often. However, its thick consistency can make it harder to rub in and blend on your skin. It might leave white residue on the skin.
Pros and cons of sunscreen
Sunscreen is more gentle and suitable to be part of your skincare routine. Due to its texture that is not too thick or greasy, it can be applied as a base before you apply foundation. However, it does not give enough protection under the intense sun exposure, if you are planning for outdoor activities.
Knowing the difference between sunblock and sunscreen isn't just about the application, but also your personal needs.
