Unopened Blue Organza Light Cream can be kept at room temperature for about 6 months. Its shelf life depends on the storage conditions. If kept in a cool, ventilated and dry place, it can last for about 3 months. If kept chilled in the refrigerator, it will keep for more than 18 months. Whichever way you store it, you need to avoid direct sunlight and excessive temperature fluctuations.

Blue Windmill Light Cream should be used as soon as possible after opening, and will generally keep for about a week. If you want to keep it longer, you can keep it in the refrigerator for up to two days. Meanwhile, when using opened light cream, you need to pay attention to the following points:

1. Use clean knives and containers to avoid contamination.

2. Don't keep the opened light cream in the freezer, otherwise it will affect its taste and quality.

3. After each use, you should fold the opening of the light cream and seal it with plastic wrap.

4. If the opened light cream has an odor or spoilage, it should be discarded immediately and not used again.

In short, both unopened and opened Blue Windmill light cream needs to be stored and used under proper conditions to ensure its quality and taste.
