Because it contains such a large amount of nutrients inside, preserving it is not easy. Many women keep their sunscreen lying around in many places, such as in bags, on top of cabinets, in direct sunlight… Because of this incorrect storage of sunscreen, the substances in the cream change. .

When sunscreen changes, you can tell that the color, texture, scent, etc. are not normal.

2. Expired sunscreen

Sunscreen, like other common cosmetics, will have an expiration date written on the packaging. Checking the expiration date of sunscreen is something that women need to do regularly to avoid using expired sunscreen without knowing it. Most women do not want to use sunscreen until the cream is dehydrated, discolored, has color variations… then they know it has expired.

And what you need to do is to preserve sunscreen better to avoid exposing it to heat and direct sunlight. In addition, you should also shake the cream bottle vigorously to prevent the product from separating.
