First of all, thank you for purchasing water code products. As for your allergic problem, there are many reasons for this problem, such as climate change, skin contact, diet, etc., which may cause skin discomfort and sensitivity. This may be caused by the following reasons:

1, the Spring Festival has just passed. Many people have sensitive skin in this season, and their skin will itch from time to time when they don't use the product, especially the phenomenon mentioned above, which is mostly caused by contact with pollen in the air and allergy to a certain fragrance. If you encounter this phenomenon, please stop using this product first, then use it after this season and try it before buying.

2, seasonal changes, fragile skin, serious water shortage. Water password products have strong hydration and permeability, so it is a bit too much to give them a lot of water suddenly. It needs a reaction to adapt to this process, so it will sting or itch. This is not an allergic phenomenon.
