Deep cleansing and heat retention that penetrates deep into pores! Ultra-fine nanobubble technology transforms water into microscopic bubbles, penetrating deep into the stratum corneum of skin and hair. It encapsulates sebum and dirt trapped in pores, cleansing from the root. Furthermore, the fine bubbles trap the heat of the water, increasing the water temperature's duration by approximately 30%. Your daily bath transforms into a luxurious beauty spa, combining pore care and warming heat retention.
