Use it at night. Because the repair and regeneration function of skin cells is more active at night, the use of skin rejuvenation products can better play its role. Before using Ji Chun Coffee Skin Rejuvenation Essence, you need to clean your skin, then evenly apply a proper amount of essence to your face and gently massage until it is completely absorbed. This essence contains coffee extract and other ingredients, which can help improve dull and uneven skin and make your skin brighter and smoother.
