Moisturizing cream is something that moisturizes our skin and is relatively convenient to use. However, why does moisturizing cream turn yellow?

Why does moisturizing cream turn yellow?

If your moisturizer turns yellow, it may be spoiled. However, the yellowing of the cream does not necessarily mean that it has gone bad. If it is a whitening, antioxidant and skin-rejuvenating product and contains vitamin C active ingredients, it will slowly oxidize and turn yellow when exposed to air. This is a characteristic of vitamin C active ingredients and is normal.

How long is the shelf life of moisturizing cream

Shelf life is three years. Generally, unopened facial cream can be stored for 3 years, but opened facial cream is recommended to be used up within 3-4 months after opening. Because the cream comes into contact with the air after opening, it will inevitably be contaminated by bacteria and microorganisms in the air, which accelerates the oxidation of the cream and causes the effectiveness of the cream to be lost faster. Therefore, the shelf life of the cream after opening will be shortened to 3-4 months.

How to store facial cream

Once you buy a facial cream and open it, it is best to put it in a place where there is no direct sunlight. A cool and dry place is the best storage environment for the facial cream, otherwise the texture of the cream will change in a short period of time. After use, the facial cream must be sealed and stored. Just cap the bottle tightly to avoid direct contact between air and the facial cream. Keep it away from humid environments to prevent the facial cream from deteriorating.

Some people think that skin care products can be stored in the refrigerator, but not all skin care products are suitable for storage in the refrigerator. Facial creams cannot necessarily be refrigerated in the refrigerator. For safety reasons, first avoid putting it in the refrigerator because its texture is frosty. If it is refrigerated in the refrigerator and then taken out for use, the texture will change due to the temperature. Finally, using it on the face will affect the effect. Finally, when a bottle of facial cream is used up, it is obvious that the effect cannot be achieved as it was when it was first purchased.

Skin care products and cosmetics will change color after being stored for a long time

If you find that the color of your cosmetics has become darker, or uneven, or has some strange spots; or sometimes the cosmetics have grown small spider web-like filaments, please throw it away immediately. The texture of the cosmetics itself can be seen visually when purchasing. If cosmetics are stored for too long and go bad, the texture of the cosmetics will become very thin, watery, and even cause water and oil separation.
