Rowan Kernel Butter

Rowan Kernel Butter, likely referring to *Sorbus aucuparia* (rowanberry) extracts, is rich in polyphenols like quercetin-3-rutinoside and isoquercitrin. These compounds provide potent antioxidant and anti-inflammatory effects, supporting skin regeneration and barrier integrity.

Origin & History

Rowan Kernel Butter is a rich lipid extract derived from the seeds of Sorbus aucuparia, commonly known as Mountain Ash. Native to Europe and parts of temperate Asia, this tree thrives in alpine forests and highland woodlands. The butter is valued in functional skincare for its hydrating, collagen-supporting, and anti-inflammatory properties, attributed to its unique fatty acid and phytochemical profile.

Historical & Cultural Context

Rowan Kernel Butter has been utilized for centuries in European folk medicine, particularly in Celtic herbalism, to treat skin inflammation, nourish dry skin, and improve complexion. Traditional ointments made from its kernels and berries were applied during winter months, symbolizing protection, renewal, and beauty for skin resilience and glow.
