Sunscreen spray is necessary in summer, otherwise you will get darker. How long is the shelf life of this sunscreen spray? What should I do if my sunscreen spray is expired?

What is the shelf life of sunscreen spray?

Generally speaking, the shelf life of sunscreen is three years, and some can be as long as five years. If the sunscreen spray is unopened and within its shelf life, it can still be used in the second year and its sun protection effect will not be reduced. If the spray is unopened but has exceeded its shelf life, its sun protection ability will be reduced. It is best to use up sunscreen within one year after opening. If you think it is a pity to throw away sunscreen after one year, you can apply it on your hands, feet, etc., which will still have a certain sun protection effect. Therefore, when purchasing, you can choose sunscreen products with a closer production date.

What to do if the sunscreen spray expires

1. Unopened expired sunscreen spray can be used to spray the body in the second year. If it is an unopened sunscreen spray but has passed its shelf life, the effective sun protection ability of the sunscreen spray will be reduced. If you can't bear to throw it away, you can use it to spray your body, but you must increase the amount of sunscreen spray so that the sunscreen spray can exert its proper sun protection value.

2. If the sunscreen you bought is expensive and has a whitening effect, it would be a waste to throw it away. We can apply it on our feet to whiten our feet. Because the skin on the feet is thicker, expired sunscreen will not cause damage to the skin on the feet, but be careful not to apply too much.

3. If you wear leather shoes or have leather shoes at home, you can use expired sunscreen to wipe the leather shoes. Just wipe them with a used towel or a soft-bristled toothbrush.

4. Sometimes, in order to make it convenient to hang things at home, such as clothes or convenience bags, some small hooks like suction cups are hung on the wall. If it takes a long time, the suction cup may not have enough pressure and will not be able to stick and fall off. At this time, we can apply sunscreen on the hook and then hang the hook up. In this way, the suction cup will be very firm.

5. When writing, sometimes we accidentally make strokes on our hands, which are generally difficult to wash off. At this time, we only need to apply an appropriate amount of sunscreen on the area with strokes, massage with our hands for a while, and then wash it off with clean water.

The shelf life of sunscreen spray is generally 3 years. If it expires, it can be used for other purposes.
