Can sunscreen still be used after two years? Can sunscreen be used for two years?

Some people tend to forget to use sunscreen, and sometimes they don’t even use it up for two years. In this case, whether two years of sunscreen can still be used, let’s find out below.

Can sunscreen still be used after two years?

Sunscreen cannot be used after two years, and it has basically no sun protection effect.

Sunscreen can be divided into physical sunscreen and chemical sunscreen. However, chemical sunscreens have better skin feel and visual effects, while people with sensitive or extremely dry skin are more suitable for physical sunscreens.

It is best to use up the sunscreen in the same year after opening it

Experts say: The sunscreen effect that is not used up this year will actually be greatly reduced next year. The sunscreen after opening, It's best to use it up that year.

Generally speaking, the shelf life of sunscreen is three years, and some are as long as five years. There are many people who have not used up this year but will continue to use it next year. There are even many people who have not used up a bottle of sunscreen for three years.

Experts say that although sunscreen is a must-have skin care product for women in summer, some people even reserve several bottles, thinking that they can’t use it up this year and will use it next year anyway, so there will be no waste. As everyone knows, this approach will not only cause sunburn to the skin, but also easily cause dermatitis. Although the shelf life of the sunscreen bottle is 3 or even 5 years, the most stable and effective period after opening is one year. If it exceeds one year, the effect of the sunscreen contained in it will be greatly reduced, and it will basically not be able to function as indicated on the label. With a high value of sun protection, it is easy to get sunburned when wearing this kind of sunscreen. If you go to a place with strong ultraviolet rays, you are more likely to get sunburned. Although sunscreen products used every other year may not necessarily have side effects on the skin, sunscreen with reduced effectiveness may not achieve the expected sunscreen effect and can easily cause the skin to become red, darkened, or even injured under direct sunlight. It is best to use sunscreen within a year after opening. If you think it would be a pity to throw away sunscreen every other year, you can apply it on your hands and feet, etc., and it will still have a certain sun protection effect. Therefore, when purchasing, you can choose sunscreen products with a closer production date. Another reminder is that you should apply a layer of moisturizer before applying sunscreen, and try not to come into direct contact with the skin. This can not only add some moisture to the skin, but also reduce irritation to the skin.

Sunscreen with powder is also refreshing

Don’t ignore it, sunscreen liquid foundation and sunscreen powder are also purely physical sunscreen products that are easy to use on the eyes! In many people’s minds, , makeup products such as foundation are still considered harmful to the skin. But in fact, because titanium dioxide and zinc oxide are both white powders with a "whitening" effect, they have long replaced traditional harmful ingredients such as lead and mercury and are widely used in powder makeup products. This has also made new types of liquid foundations and powder cakes All have sun protection properties. Moreover, in order to make the makeup last longer, the SPF of liquid foundation and powder should not be very high, and the texture should never be greasy. Also because it contains moisturizing, oil-controlling, and oil-absorbing ingredients, as long as you choose the right product, you can make dehydrated skin more moisturized and oily skin feel refreshed.
