Thank you for viewing! ☆ Brand new, unused ☆ Free shipping This showerhead uses advanced German nano-technology to convert water flow into approximately 500 million ultra-fine nano-bubbles (less than 1μm), providing skincare and haircare benefits. Micro-nano bubbles, smaller than pores, penetrate deep into the skin, thoroughly cleansing away dirt, sebum, and makeup residue that tap water alone cannot remove. Furthermore, unlike regular bubbles, ultra-fine nano-bubbles release oxygen while stably maintaining water temperature, allowing for a more enjoyable and extended bath time. Simultaneously, they lock in skin moisture, improving dryness and roughness, leading to fresh, vibrant skin!
