Althaea Officinalis Leaf Extract

Althaea officinalis leaf extract comes from the marshmallow plant, a herb with a long history in traditional medicine and skincare. The extract is derived from the leaves and contains polysaccharides and mucilage compounds that give it skin-conditioning properties.

In skincare formulations, this ingredient functions as a humectant and skin conditioner, helping to hydrate and soften the skin's surface. It's generally well-tolerated and often chosen for its gentle profile, particularly in products targeting sensitive or compromised skin barriers.

Althaea officinalis works primarily through its polysaccharide and mucilage content, which forms a protective layer over the skin. This occlusive effect helps trap water in the stratum corneum, the outermost layer of skin, improving hydration and tactile softness.

The extract's traditional association with soothing and anti-inflammatory effects is likely linked to these same compounds, though the exact mechanisms in skincare require further research. Its gentle nature makes it suitable for use alongside other active ingredients in most formulations.

This ingredient is typically found in hydrating serums, moisturisers, and soothing treatment products. It works well alongside other humectants like glycerin and hyaluronic acid, and can be used daily as part of both morning and evening routines. No special application technique is required; simply apply to clean skin before moisturiser.
