Althaea Rosea Root Extract

Althaea rosea root extract is derived from the roots of the hollyhock plant (Althaea rosea), a traditional botanical ingredient used in skincare formulations. The extract contains polysaccharides and mucilaginous compounds that give it hydrating properties.

In skincare products, it functions primarily as a humectant—a substance that draws water from the air and deeper skin layers to the surface, helping to improve skin hydration and maintain moisture content in the stratum corneum.

The extract works through its humectant properties, primarily owing to its polysaccharide content. These molecules are hygroscopic—they attract and bind water molecules, drawing them toward the outer layers of skin.

Additionally, the mucilage compounds in the extract may form a light conditioning film on the skin's surface, helping to reduce transepidermal water loss and maintain the skin barrier's hydration status.

This ingredient is typically found in serums, hydrating toners, and moisturisers where it works alongside other hydrating or humectant ingredients. For best results, apply it to damp skin to maximise its water-binding capacity, then follow with an emollient or occlusive product to seal in hydration. It can be used daily as part of a standard skincare routine.
