Rosa Rubiginosa Fruit Extract

Rosa rubiginosa fruit extract is derived from the fruit of the rosehip plant, native to South America. It is particularly valued for its high concentration of essential fatty acids, predominantly linoleic acid (approximately 41%) and linolenic acid (approximately 39%), which are key structural components of healthy skin.In skincare formulations, this ingredient functions as an emollient and skin conditioning agent. These fatty acids help to support the skin's natural lipid barrier, which is responsible for retaining moisture and protecting against environmental stressors.

The skin barrier is composed partly of lipids (fats) that sit between skin cells, acting as a sealant. When this barrier is compromised—through damage, dryness, or sensitivity—moisture escapes and irritants penetrate more easily. Rosa rubiginosa fruit extract delivers linoleic and linolenic acids that can integrate into this lipid matrix, helping to restore its integrity.As an emollient, the oil also forms a protective film over the skin surface, reducing transepidermal water loss (the evaporation of water from the skin) and providing immediate comfort and softness.

Rosa rubiginosa fruit extract is typically incorporated into serums, oils, creams and balms. It works well layered into a skincare routine after cleansing and toning, either as a standalone oil or as part of a moisturiser. Because it is an occlusive emollient, it may feel heavy if over-applied; start with a small amount and adjust to your preference. It can be used morning and evening, though evening application may be preferred by those with oily skin or in warm weather.

Rosa rubiginosa fruit extract is generally well-tolerated and has a good safety profile in skincare. Those with known sensitivities to rosehip or plant oils should patch-test first.
