What Rhamnose does

Attracts and holds water in the skin
Helps keep skin soft and supple
Helps leave skin comfortable after rinsing

Rhamnose is a simple sugar that occurs naturally in plants, where it is part of larger structures in plant cell walls, such as pectin. It is a gentle, water-loving ingredient that suits many kinds of skincare.

Formulators use rhamnose mainly as a humectant. Its molecules attract water, which helps keep the outer layer of skin supple. Because it dissolves easily in water, it blends into light products such as micellar waters, cleansers and moisturizers. It helps those products feel comfortable and hydrating without a heavy finish.

Good for

Suits people with dry or tight-feeling skin, and gentle everyday products like cleansers and micellar water.

Frequently asked questions

Is rhamnose safe for sensitive skin?

Rhamnose is generally well tolerated by most skin types. As with any new product, a small patch test on the inner arm is a sensible first step, especially for sensitive skin.

Does rhamnose make skin feel dry or tight?

No. As a humectant, rhamnose is meant to draw water into the skin's outer layer, so it helps skin feel comfortable rather than tight. Its effect depends on the whole formula, including moisturizers and oils used with it.
