Luna air cushion is suitable for sensitive skin. Made of ultra-fine and soft materials, it does not contain any irritating ingredients, which can well avoid discomfort to the skin. It also has a moisturizing effect and can replenish enough moisture to the skin during use. But for the sake of safety, it is suggested to do a sensitivity test before using luna air cushion. Apply a small amount of liquid foundation to sensitive parts such as wrists or behind ears, and wait for several hours to see if there is allergic reaction.
