Why is using sunscreen every 2 hours important?

One of the good and correct uses of sunscreen is to use it every two hours. This has been recommended by most dermatologists. So, why is it so 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 are capable of working well to protect the skin from UVB rays. However, there are two drawbacks to this sunscreen.

First, sunscreen only lasts about 2-3 hours after use. Second, usually the use of this sunscreen can redden the skin. This 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 so important to use sunscreen every two hours. If you do most of the outdoors, you really need a sunscreen that is high SPF and waterproof.

When you are outdoors, you are likely to be exposed to the sun so often, that it is 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, you should use sunscreen 30 minutes before doing any activity outside. It is very important that you re-apply it every two hours, so that your skin can be properly protected. Don't 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 shouldn't rely on sunscreen alone to protect us from the sun. Sunscreen doesn't really keep us from sunburns, blisters, to cancer. Of course, other protection is needed to optimize this sunscreen so that we avoid the bad effects of solar radiation.

• Uses SPF 30 lip balm
• Hat
• Sunglasses with UV protection
• Long sleeved clothes

Well, don't forget to know that solar radiation has bad effects from 10 am to 4 pm. Try to reduce your outside activities at these times.

Myths surrounding the use of sunscreens

After knowing the reasons why we should use sunscreen every 2 hours and how to optimize it, it turns out that there are several myths about sunscreens that are often believed by us.

1. Sunscreen can cause vitamin D deficiency

This myth is still a matter of controversy. However, some dermatologists believe that sunscreens can cause our skin to become deficient in vitamin D. However, there is no research that really proves this. Apart from 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 solar radiation, even though at that time the weather was cloudy. Therefore, the use of sunscreen should still be done when you are outside, even if the weather is cloudy.

Sunscreen with high SPF is certainly very beneficial for our skin. Moreover, using it properly and as directed can optimize the benefits of this sunscreen. Don't forget to always use sunscreen every 2 hours, when you are outside.
