The reason for this is the following：
1. After the mask is applied to the face 15~20 minutes, the skin is already saturated. If you don't wash the nutrient solution off your face, you can directly apply other skin care products, which will affect the skin's absorption of these skin care products.
2. If the nutrients on the mask stay on the face for too long, people with sensitive skin are prone to acne or erythema.
3. The skin can't work in high humidity for a long time, which will affect various functions. Therefore, under normal circumstances, the time for applying the mask should not exceed 30 minutes, and it can be maintained at about 20 minutes. Sleep mask is actually a kind of night cream, which is not in this range.
How to apply the mask correctly according to the correct steps? 1. After bathing or soaking, the pores open and the skin is full of moisture. At this time, the effect of applying face is the best! At the same time, you can also apply a hot towel to your face first, and the effect is the same.
2. Clean the face before applying the mask, then color the skin, and use the essence as the base first, which has guiding and strengthening effects. Apply whitening mask with whitening essence, or apply moisturizing essence before applying moisturizing mask.
3. Lie down and apply a mask centered on the middle of a person's nose, smooth the mask paper from the inside out, and push out the air inside. The peripheral part must be supple, otherwise it is easy to become warped because the mask paper is dry. Then put on headphones to listen to some light music, close your eyes and enjoy quietly 15-20 minutes.
4. After taking mask paper, there are often many essences on the face, and massage can help the skin absorb nutrients; The mask removed from the face can also be applied to the neck, which will not only be wasted, but also avoid the widening skin color gap between the face and the neck.
5. After massaging the skin and absorbing it, we can rinse it with clear water a little, and then we can carry out the skin care process.
