A lotion should be applied before all your other skincare products.
Tip: pour a few drops into the palm of your hand, then pat over the face with the fingertips. Apply your moisturizer within the next 30 seconds in order to enhance its benefits.
In the morning, a lotion will wake up your skin and remove excess sebum that has built up overnight. It allows your skin to wake up much more gently than it would with just soap-based cleansing.
In the evening, you can apply a lotion before your night cream to really boost its moisturizing benefits overnight.
You can also use a lotion to make your own sheet mask. Take a non-saturated capsule mask and soak it with the lotion of your choice for a few minutes, then apply to the face. Choose your lotion according to your skin concerns, so you can give your skin exactly the ingredients it needs!
