One using a good and correct sunscreen is used every two hours. This is indeed already recommended by most dermatologists. Well, why is it very important to use sunscreen every two hours?
The reason for the importance of using sunscreen every two hours
Most sunscreens with SPF 15 or higher in content, are able to work well protecting the skin from UVB rays. However, there are two disadvantages of the sunscreen.
First, sunscreens only last around 2-3 hours after use. Second, usually the use of sunscreen can redden the skin. That is because it only protects UVB rays, so there is a possible effect of UVA that you can get.
Well, the duration of this endurance is one of the factors why it is very important to use a sunscreen every two hours. If you often do outdoor activities, you really need a sunscreen with high SPF and waterproof.
When you are outdoors, chances are you are very often exposed to sunlight, so it will be very easy to sweat. Therefore, waterproof sunscreen is highly recommended because it will not fade quickly when sweating.
In addition, so that your skin does not burn quickly, sunscreen must be used 30 minutes before moving outside. It is very important for you to use it again every two hours, so that your skin can be protected properly. Do not forget to use it again after swimming, exercising, or after using a towel.
Tips for optimizing the use of sunscreen
First of all, the thing to remember is that we must not rely on sunscreen alone to protect from sunlight. Sunscreen does not really protect us from burning skin, blisters, to cancer. Of course other protection is needed to optimize this sunscreen so that we avoid the adverse effects of solar radiation.
- Using SPF 30 lip balm
- Sunglasses with UV protection
- Long-sleeved clothes
Myths surrounding the use of sunscreen
After we know the reasons why you should use a sunscreen every 2 hours and how to optimize it, it turns out there are some myths about sunscreen that are often believed by us.
1. Sunscreen can cause vitamin D deficiency
This myth is actually still a controversy. However, some dermatologists believe that sunscreens can cause our skin to be deficient in vitamin D. However, there is no research that actually proves this. Besides being sourced from sunlight, vitamin D can also be obtained from salmon, eggs, or milk.
2. No need to use sunscreen if the weather is cloudy
Of course this is very wrong. Our earth is still exposed to about 40% of the sun's radiation, even though it was cloudy at that time. Therefore, the use of sunscreen should still be done when you are outside, even though the weather is cloudy.
Sunscreen with a high SPF is certainly very beneficial for our skin. Moreover, using it correctly and as recommended can optimize the benefits of the sunscreen. Don't forget to always use a sunscreen every 2 hours, when you are outside.
