Not all skin care products are suitable for refrigeration. Here are some types of skin care products that are suitable for refrigeration:

1. Facial masks: Especially hydrating and repairing masks, refrigerated use can help cool down and repair sun-sunned skin and promote capillary contraction.

2. Oil-free skin care products: such as lotion, aloe vera gel, frozen mask, etc., can calm and soothe the skin after refrigeration.

3. Special ingredient essences and stock solutions: Products containing easily oxidized ingredients such as vitamin C, epidermal growth factor, etc. are recommended to be stored in the refrigerator after opening to slow down the oxidation rate of the ingredients and maintain their activity.

The following skin care products are not suitable for refrigeration:

1. Oil products: makeup remover, essential oil, moisturizing oil, etc. Refrigeration may cause chemical changes in the oils and fats, affecting the product effect.

2. Lotions and creams: Low temperatures may destroy their emulsification structure, causing water-oil separation and accelerating the ineffectiveness of active ingredients.

Most skin care products can be stored in a cool, dry, dark environment without refrigeration. For those products that need to be refrigerated, they should be stored until they are used up, avoiding alternating hot and cold conditions to avoid accelerating product deterioration. Remember, refrigeration is for preservation, not freezing, which can damage the product.
