Can I still use the serum if it's expired?

Cosmetics are all synthesized from chemical substances. After they expire, they may undergo other chemical changes. Because of different environmental conditions such as temperature and humidity, the changes produced are also different. They cannot be seen with the naked eye, and we don’t know what side effects these changes will have, so it is best not to use them.

How to check expiration:

You can check the production date and expiration date on the packaging. Serums have a shelf life of up to two years, although the box usually states three years. You should know that the best shelf life of the active ingredients in the essence is only six months after leaving the factory. Serum will oxidize. However, even so, you will still see some effect if you use a serum that is more than two years old, but the speed of effect and the maintenance results will not be as good as those of newer products. You’ll also notice that serums tend to come in smaller containers than creams and lotions, so they can be used up faster and in a shorter period of time, alleviating your concerns about shelf life.

What is the use of expired serum?

Once the essence has expired, it cannot be used on the face. It can be used on hands and feet though. Essence is the best of skin care products, with exquisite ingredients, powerful efficacy and remarkable results, and it always maintains its nobility and mystery. The essence contains trace elements, collagen, and serum, and its functions include anti-aging, anti-wrinkle, moisturizing, whitening, and freckle removal, etc. Essences come in two types: water-based and oil-based. They extract highly nutritious substances and concentrate them.

Can whitening essence be used in the morning? How to use it in combination with other essences: I understand that everyone will worry whether the ingredients in whitening essence will be photosensitive and make them darker. In fact, the technology and packaging used in most whitening products (for example, Kiehl's whitening essence is packaged in a transparent bottle. If it cannot be used during the day, the brand would not package it so confidently) can be used during the day. Especially some whitening essences, which are labeled to resist sunlight erosion when used during the day. Of course, there are some products that are specifically marked not to be used during the day, so you should pay attention and only use them at night. It is best to use whitening essence after moisturizing essence. Moisturizing essence can provide a base for the skin and allow the skin to better absorb subsequent products.

I think you all understand that expired essence cannot be used on your face.
