[Warm Nano Steam] Gentle warm nano steam envelops your entire face, penetrating the stratum corneum of the skin. It transforms skin hardened by dryness or old keratin into moist, hydrated skin with steam. *Nano size refers to fine particles that are 1/1,000,000th of a millimeter. [For Deep Cleansing (Before Removing Makeup)] Apply steam before removing makeup. By opening the pores, it lifts sebum and makeup residue remaining deep within the pores, making them easier to remove. [For Thorough Moisturizing Care (Before Skincare After Washing Your Face)] Apply steam to clean skin after washing your face. By opening the pores and softening the skin, lotions and serums penetrate the stratum corneum of the skin. [To Improve Makeup Application (After Washing Your Face Before Makeup)] Apply steam before applying makeup. By thoroughly moisturizing the skin, makeup application is improved. [For Various Scenes] Relax by enjoying the warm mist. It is also recommended to use the steamer with a face mask. You can also use it on the ends of dry hair or your décolletage. There is no outer box or instruction manual. I plan to wrap it in bubble wrap and ship it in a cardboard box. Care: Warmth/Moisturizing
