The reason for this is that ointment products tend to have larger molecules and higher moisture retention, and will form a film on the skin surface after application. If you apply this kind of product first, it will be difficult for the water-like and essence-like products with smaller molecules to be absorbed by the skin again, let alone play a role.
Don't use skin care products that have expired. Many ingredients in cosmetics will decompose and change after a long time, which is easy to cause skin damage. Generally, use Polaiya whitening and freckle removing skin care products for no more than 15 minutes. Because the mask is used for a long time, the face will be deprived of oxygen, which will lead to yellow skin color. Moreover, if the mask is applied for too long, the nutrients originally absorbed by the facial skin will be sucked back, including the original moisture of the skin, and will also be taken away by the mask paper.
The use frequency of Polaiya whitening and freckle removing skin care products depends on the skin condition of the day, generally speaking, it is once in the morning and once in the evening. If the skin feels a little exuberant in oil secretion at noon, it can be increased once at noon. When using cleaning products, we should pay attention to the appropriate technology. After wetting the face, pour the cleansing product into the palm of your hand, knead the foam, massage with your fingertips along the corners of your mouth to the corners of your eyes, and gently massage your forehead along your eyebrows to your temples, from bottom to top and from inside to outside.
