Should whitening essence be used during the day or at night? Because there are many sayings on the Internet that whitening essence cannot be used during the day, many girls are always worried that it will bring side effects to the skin after using it during the day. So let me tell you whether the whitening essence should be used during the day or at night. Let’s take a look~

Should I use whitening essence during the day or at night?

If whitening essence is not specifically marked as not being used during the day, then it can be used both during the day and at night. There are also some whitening essences that are not marked as not suitable for daytime use, but they contain some ingredients that are not suitable for daytime use, so they are not suitable for daytime use.

Which whitening essences cannot be used during the day?

Contains pure vitamin C

If the whitening essence used by girls contains pure vitamin C, it is not recommended to use it during the day. Because pure vitamin C has a certain photosensitivity effect, if used during the day, it may absorb more ultraviolet rays and make the skin darker, so it is not recommended to use it during the day.

Fruit acid

If the whitening essence used by girls contains fruit acid ingredients, it is not recommended to use it during the day. Because the fruit acid ingredient itself is somewhat irritating, using it during the day, coupled with the stimulation of ultraviolet rays, will cause skin discomfort.

Retinol

Retinol is an antioxidant ingredient that is photosensitizing and will more easily absorb UV rays after use. Some whitening essences also add this ingredient to achieve an antioxidant effect, so when girls use whitening essences, it is best to check the ingredients carefully in advance.

When is the best time to use whitening essence?

Evening 20:00-22:00

If girls use whitening essence at night, then 20:00-22:00 is the best time to use it. Because this time period is when the body's metabolism is most active. If you use whitening essence at this time, the skin can absorb it better, thus achieving the best effect of the whitening essence.

One week after your period

Girls can also achieve the best results by using whitening essence one week after their menstrual period. Because the body secretes more estrogen than usual at this time, and the skin is very stable and not prone to allergies, so this is also the best time to use whitening essence.
