The power of plants

Originating from Western Europe, the houseleek – whose Latin name “sempervivum” means “always alive” – has a certain air of immortality about it. Maybe that’s why the Ancients associated it with Jupiter, king of the gods, and endowed it with occult powers: planted on the roof of a house or place of worship, the houseleek was believed to protect against lightning and evil spirits and guarantee long life. The plant also has interesting botanical features: when subjected to extreme temperatures, drought and arid soils, it still retains its green, fleshy, succulent leaves. Drought-loving plants such as houseleek develop a number of morphological and physiological mechanisms to survive hydric stress. It blooms in poor, rocky soils resistant to temperature variations and desiccation. Its adaptation is rooted in two characteristics: a waxy cuticle that reduces evapotranspiration and a CAM metabolism where the plant absorbs CO2 overnight and carries out photosynthesis during the day. Studies have confirmed that the houseleek owes its capacity to fight intense hydric stress to highly developed physiological and biological mechanisms. Clarins has studied these abilities as part of its research into hydric stress, among 130 other plants.

Skincare benefits of Organic houseleek extract

In cosmetics, organic houseleek extract helps the skin to resist dehydration. It promotes the expression of Claudin-1, a key protein in tight junctions which plays a dual role: as a secondary epidermal barrier, it minimizes water loss and maintains intracellular water balance. This guarantees the proper functioning of keratinocytes in the granular layer, namely the secretion of lamellar bodies which are essential to the production of intercorneocyte cement.

Responsible sourcing

Our houseleek is grown in France in accordance with organic farming principles. It grows at our Domaines among other plants. Nestled at the heart of the Alps at an altitude of 1400 metres, Domaine Clarins Serraval is an open-air laboratory and an exceptional source of organic raw materials. We have grown our own ingredients here since 2016 in rhythm with the seasons. This unique establishment prides itself on respecting the fauna and flora: its regenerative agriculture method (in full compliance with natural habitats and cycles, natural inputs, etc.) strengthens soils and biodiversity. Domaine Clarins Serraval reflects the commitment of the Clarins team in charge of the establishment, which works continuously alongside regional agricultural partners, all of whom share the same attachment to the planet and their professions.
