Onsen Lab takes its name as well as its cosmetic inspiration from the Japanese hot springs frequented by women as far back as the 10th century. These springs' mineral-rich waters were renowned for nourishing and revitalizing skin, and to recreate similar effects Onsen created products that combine these natural mineral elements with scientific advancements in the aesthetic field.

The company's signature Micro Water Complex is the foundation for all its formulas. Using molecules much smaller than water, they can penetrate the skin more deeply while balancing pH levels and delivering nutrients. Depending on which product line it's used in, the Micro Water Complex can help clear clogged pores or minimize the appearance of wrinkles, age spots, sun damage, excessive redness, and stuck-on clown noses. Onsen formulates toning, exfoliating, and moisturizing balms for the face, the body, and even the hands and feet.
