Exposed to UV rays, aka sunlight besides burning the skin can also cause skin cancer. Well, one effective way to prevent skin damage is to use sunscreen.
What exactly is sunscreen?
Sunscreen is a skincare product in the form of lotions, sprays, gels, foams, or sticks that can be used to protect the skin from UV radiation, both UVA and UVB.
Although UVA and UVB are equally bad for the skin, UVA rays cause even more damage because they can penetrate the deepest parts of your skin. Just imagine, UVA radiation can penetrate clouds and glass, be it during the day, night, even when the weather is cloudy. UVA rays can accelerate skin aging and cause wrinkles and dark spots.
While UVB (Ultraviolet-Burning) is sunlight which has a wavelength smaller than UVA rays. UVB rays do not penetrate glass and clouds, but radiation is much stronger than UVB. Short exposure to UVB can cause sunburn.
If the skin is often exposed to these two rays, your risk of developing skin cancer is even greater.
Types of sunscreen
Based on the materials used, sunscreens are categorized into two types, namely:
Works by making layers on the surface of the skin so that it can prevent UV rays from penetrating the inner skin layer. This sunscreen usually contains active ingredients such as zinc oxide and titanium dioxide.
Works by making a layer on the surface of the skin to absorb UV radiation energy, so it is not absorbed or enters the inner skin layer.
Sunscreen chemicals contain several active ingredients such as cinnamon, octisalate, oxybenzone, dioxybenzone. This type of sunscreen is often called sunscreen.
Most sunscreen formulations sold on the market are a combination of physical and chemical.
Unlike the sunblock and sunscreen
Sunblock, an inaccurate term because there is no single ingredient in it that can block UV rays. In fact, in America, the use of the word sunblock has actually been banned by the FDA.
So, the term sunblock has been reused, because it is more appropriate to use the term sunscreen.
The importance of using sunscreen every day
The effect of UV exposure can be felt in the short and long term. Some short-term impacts include:
- Sunburn (sunburn)
- Dark skin
- Dark skin
- Dull skin
While the long-term impacts include:
- Skin aging
- Skin wrinkles
- Sagging skin / not tight
- Brown spots or black spots appear
- The risk of skin cancer
If you don’t want to experience the various effects above, then don’t forget to use sunscreen every day, especially when you are outdoors. Not only adults, but babies also have to use sunscreen every time they are taken out of the house. However, the use of sunscreen is recommended for babies over 6 months of age.
Remember, UVA rays haunt you every day, even if it’s cloudy. So, don’t be lazy to wear sunscreen every time you are outdoors.
Don’t forget, use sunscreen every 2 hours
You are certainly familiar with suggestions for using sunscreen every 2 hours. However, yes, it must be 2 hours?
In fact, although sunscreen effectively blocks sunlight from penetrating the skin, its protective strength will decrease over time from the beginning of use. Whether it’s because of sweat, friction with the skin, facial expressions, or so on.
So, if you want to get maximum protection, sunscreen needs to be repeated regularly every 2 hours. Especially if your daily activities outside the room that allows exposure to direct sunlight.
You should also use sunscreen if you are in a room that is still exposed to sunlight, for example, there are windows and doors that allow sunlight to enter or there is a glass ceiling. As mentioned above, UVA rays can penetrate glass.
