Creams are divided into two types of emulsions: "oil-in-water" (o/w) and "water-in-oil" (w/o). See (1) Dilution method for an explanation. Oil-in-water (o/w) creams are easily soluble in water, while water-in-oil (w/o) creams are insoluble in water but soluble in oil. These are the properties of the two emulsions and cannot be used to judge the quality of the cream. There are other ways to test the emulsification properties of a cream. The simplest and most practical way is to apply the cream on your hands and rinse with water. If there is no greasy feeling after washing, it is an oil-in-water cream. If there is still a greasy feeling after washing, it is an oil-in-water cream!

The above is the result that can be obtained by testing the lotion with water. It can be seen that this method cannot measure the quality of the lotion.

Season: Lotion can be used in any season, but there are slight differences depending on the skin type. For dry skin, lotion should be used in summer; for oily and neutral skin, lotion can be used all year round; for combination skin, lotion should be used in spring and summer.

Time: As a skin care product that moisturizes and locks in moisture and protects the skin from external stimuli, lotion should be used after cleansing every morning and evening. In the skin care steps, it should be placed after cleansing, toner, eye cream, and essence, and it should be applied after ensuring that all previous skin care products are absorbed.

Okay, my friends, now you know when to use lotion.
