What is the difference between the blue tube and yellow bottle of Biore sunscreen? Why can it only be used for one year after opening?

Biore sunscreen comes in many styles, there is always one that suits you. So, how many have you used? What’s the difference between the blue tube and yellow bottle of Biore sunscreen? Let’s take a look at it together.

The difference between the blue tube and yellow bottle of Biore sunscreen

Both sunscreens are suitable for face and body use, and the sun protection effect is still good. Apart from some differences in SPF, texture and suitable groups, in fact, as long as you choose the one that suits you in terms of usage feeling and sun protection effect, it will be fine.

It is not recommended to spray sunscreen spray directly on the face

1. There is an inhalation risk

When using, avoid inhaling the gas into the lungs and do not spray it into the eyes and mouth. Sunscreen sprays are all chemical sunscreens, and they use butane and isobutane as auxiliary propellants, so after we inhale them into our bodies, it can easily cause damage to our lungs. It is not recommended to use sunscreen spray, especially for special groups such as children and pregnant women. If you want to use it, you can spray it on the body.

2. Easy skin

General sunscreen spray uses liquefied petroleum gas or other liquefied gases as propellants. These gases are easily volatilized in the air, and when volatilized, it is easy to take away the heat from the skin surface, which is easy to damage the skin.

Why can Biore sunscreen only be used for one year after opening?

If Biore sunscreen is opened and left for the second year, the ingredients in it will come into contact with oxygen and will be oxidized or volatilized. It will also be easy to breed and deteriorate. In addition, the plastic bottle of the packaging will also degrade. The sun protection effect will be greatly reduced and it will basically not have the sun protection effect as marked. It is easy to get tanned if you apply such sunscreen, and it is even more likely to get sunburned if you go to places with strong ultraviolet rays. Although using Biore sunscreen from the previous year will not necessarily have side effects on the skin, sunscreen with reduced effectiveness may not achieve the expected sun protection effect and can easily cause the skin to turn red, darken, or even get damaged under direct sunlight.
