Why should night cream be kept away from light?

Because many night creams contain photosensitive ingredients, using them during the day or on skin that is exposed to light may cause your skin to turn darker.

Some night creams contain photosensitive ingredients, such as vitamin A or fruit acid. If you use such night creams during the day, it will easily cause your skin to darken after being exposed to direct sunlight outdoors. Therefore, night creams are not suitable for use during the day.

Day creams generally contain certain sunscreen ingredients to a certain extent, but night creams have more nourishing and repairing ingredients. If you use night cream during the day, firstly, you fail to protect against the sun, and secondly, you fail to absorb nutrients well. Generally, it is like this: after cleansing your face, use toner and lotion, and then apply a thick layer of night cream. If your skin is dry, you can also add a sleeping mask, but do not use the sleeping mask before the night cream, as it will not work. Be sure to use the sleeping mask after using the night cream to lock in the nutrients and prevent them from being lost.

Some of these ingredients will turn black due to the influence of ultraviolet rays.
