Ulmus Fulva Bark Extract

Ulmus fulva, commonly known as slippery elm, is a tree native to North America. The bark extract contains mucilage — a naturally occurring polysaccharide that forms a slick, protective layer when mixed with water. In skincare, this mucilaginous property is utilised for its potential moisturising and film-forming capabilities.The extract is incorporated into formulations primarily for its hydrating and protective functions, though it has a long history in traditional herbal medicine for soothing applications.

The polysaccharides in slippery elm bark extract have an affinity for water and form a viscous layer on the skin. This creates an occlusive film that may help minimise transepidermal water loss and support the skin's natural moisture balance.The extract may also possess mild anti-inflammatory properties, though the mechanism in topical application is not extensively characterised in modern skincare research.

Ulmus fulva extract is typically found in moisturisers, hydrating toners, and soothing serums. Use as directed on the product label — usually once or twice daily as part of your regular skincare routine. It works well layered with other hydrating or barrier-supporting ingredients.

Generally well-tolerated and suitable for most skin types, including sensitive skin. No major contraindications reported, though anyone with a known allergy to Ulmus species should avoid.
