Althaea Officinalis Root … Leaf Extract

This is a multi-botanical extract combining seven plant ingredients: marshmallow root, chamomile flower, fennel fruit, houttuynia cordata, lavender flower, basil flower, and rosemary leaf. Each plant brings its own profile of volatile oils, polysaccharides, and phenolic compounds, which work together as a skin conditioning agent.The extract is typically used in skincare formulations to support skin comfort and hydration. The individual botanicals have been used traditionally in herbal preparations, though their efficacy in modern skincare products depends on concentration, formulation stabi…

The extract works primarily through humectant and emollient mechanisms. Polysaccharides from marshmallow root and other botanical sources draw moisture into the outer layers of skin, whilst the oils and plant compounds help to soften and condition the skin surface. This combination creates a film-forming effect that reduces transepidermal water loss.The volatile oils in lavender, basil, and rosemary may also have mild antimicrobial or anti-inflammatory properties, though their potency in a skincare product will depend heavily on how the extract has been processed and stabilised.

This ingredient is typically found in serums, toners, hydrating mists, and moisturisers at concentrations where it functions as a secondary active. It can be used daily as part of a broader skincare routine. Since it is a complex botanical blend, conduct a patch test if you have known sensitivities to any of the individual plants, particularly if you have fragrance sensitivity or are prone to contact dermatitis.

Generally well-tolerated in skincare products. However, those with allergies to plants in the Asteraceae family (such as ragweed) should be cautious with chamomile. The blend contains botanicals with mild fragrance, which may irritate very sensitive skin.
