Will the essence become ineffective if it is left for a long time? What are the functions and effects of the essence?

I originally wanted to buy a bottle of essence for skin care, but I ended up forgetting about it. Will this essence become ineffective if it is left for too long? Can I still use the essence after it has been stored for a year?

Will the essence lose its effectiveness after being stored for a long time?

If the essence is kept for a long time, some of its ingredients will become ineffective or change. If you continue to use it, it will not be good for your skin. The shelf life of the essence is three years, but it is best to use up the essence within one year. Do not throw away expired essence, it can be used to maintain clothes and leather items.

Can the serum still be used after one year?

Whether the essence can be used after being opened for one year depends on the actual situation. The packaging of essence is generally quite tight, and it is squeezed through a nozzle after opening. Most essences used in this way will not have any major problems even after one year of opening. Basically, it can be used if there is no obvious irritation reaction after applying it to the skin.

Is it okay to refrigerate the serum?

It is a misunderstanding to put cosmetics in the refrigerator, unless you use a special refrigerator for cosmetics, and not all cosmetics are suitable for storage in the refrigerator.

Skin care products: Skin care products can be divided into cleansing (facial cleansers, cleansing creams), moisturizing (day and night creams), skin care (facial masks, essences) and other products. Generally speaking, as long as they are placed in a cool place, the quality of the products can be ensured.

Lotion products can be put back into the original packaging box and placed on the bottom shelf of the refrigerator. Do not place them directly next to the refrigerator door, because the exchange of cold and hot air during the opening and closing of the door is most likely to cause the product to deteriorate.

Before storing cream-based skin care products, you should first wipe the bottle mouth and cap with alcohol-containing lotion or 75% diluted alcohol, tighten it, then put it back into the original packaging box and store it in a cool place (no need to put it back in the refrigerator). Through such treatment, not only the quality of the product can be maintained, but also some residual bacteria can be killed.

Skin care products that are not in use temporarily should be placed in a ventilated and cool place, or in a dry drawer. They should not be exposed to direct sunlight or placed in the bathroom. It is a wrong practice to put skin care products in the refrigerator. Not only is the temperature too low not good for the skin care products, but the temperature difference inside and outside the refrigerator and in and out of the refrigerator will cause the skin care products to deteriorate prematurely.

What are the functions and effects of essence

The essence contains certain active ingredients and has a very good moisturizing function. Long-term use of a good essence can have a better moisturizing effect on the skin. Water is very important for women's skin. Sufficient moisturizing and locking in moisture can prevent the skin from aging too quickly. Now a variety of reasons have combined to affect the skin and make it in an unbalanced state. The carbonic acid ions in the essence can promote skin cell regeneration and slowly alleviate the unbalanced state of the skin.
