Rosa Rubiginosa Seed Oil

Rosa Rubiginosa Seed Oil is extracted from the seeds of the wild rose (Rosa rubiginosa), native to South America. The oil is characterised by its high concentration of linoleic acid (around 41%) and linolenic acid (around 39%), which are essential fatty acids that play a structural role in the skin barrier.In skincare formulations, this oil functions as an emollient, meaning it softens and conditions the skin by forming a protective layer. It is typically used at very high concentrations in products, often appearing as a primary ingredient.

The high concentration of linoleic and linolenic acids in Rosa Rubiginosa Seed Oil allows these molecules to integrate into the skin's lipid matrix—the fatty layer between skin cells. This reinforces the barrier and reduces water loss, which is particularly important for compromised or sensitised skin.The oil's emollient action also creates a protective film on the skin surface, which may support the skin's natural healing processes by maintaining a stable environment.

Since this oil is typically found at high concentrations in products, a little goes a long way. Apply to clean, damp skin to help seal in hydration. It can be used alone or layered under other products. Some people prefer to use it in the evening due to its occlusive nature, though this depends on individual skin and preference.

Generally well-tolerated with minimal reported side effects. However, as with all plant oils, patch test first if you have sensitive skin or known plant allergies. Those prone to fungal acne should be cautious, as oils can occasionally trigger or worsen this condition.
