Three years. The shelf life of Neutrogena sunscreen is three years, but we need to note that this is the shelf life when the product is unopened. After opening, the shelf life of the sunscreen is reset to one year, and the sunscreen must be used up within one year.

Can I still use Neutrogena sunscreen after it expires?

Neutrogena sunscreen cannot be used after it expires, because the sunscreen ingredients in it have completely lost their effectiveness and will not have any effect when used again. Moreover, the texture of Neutrogena sunscreen will change after it expires. If you use it again, it may cause allergic reactions such as redness and fever on your skin. Therefore, never use Neutrogena sunscreen after it expires.

Is Neutrogena sunscreen a physical sunscreen?

The physical ingredients use sunscreen particles to form a protective layer on the skin surface, reflecting ultraviolet light waves that may cause damage to the skin, thereby protecting the skin. The particles of physical sunscreen generally stay on the surface of the skin and are not absorbed by the skin, so they cause less burden on the skin and are less likely to cause skin sensitivity.

The correct way to use physical sunscreen

Since the protective layer of physical sunscreen is in the form of a mesh, it is not advisable to apply it in circles. Instead, it should be applied sequentially in the direction of hair growth so that the protective layer is evenly distributed and it is not easy to clog pores and cause other skin problems.
