1. Wait for face cream to be fully absorbed: Generally, after applying face cream, you need to wait about 30 seconds to 1 minute to ensure that face cream is fully absorbed by the skin.
2. Check the skin condition: gently touch the face to ensure that there is no residual face cream, and the skin feels dry and not greasy.
3. Apply the isolation cream: after the face cream is completely absorbed, you can start to apply the isolation cream. This step is to form a protective barrier between the skin and the external environment, while adjusting skin tone or providing sun protection and other functions.
