Description

Rosa Rubiginosa Seed Oil, commonly known as rosehip seed oil, is extracted from the seeds of the Rosa rubiginosa plant, which belongs to the Rosaceae family. This oil is highly valued in the cosmetic and personal care industry for its rich content of essential fatty acids, vitamins, and antioxidants. Known for its regenerative and healing properties, Rosa rubiginosa seed oil is increasingly recognized for its benefits in modern skincare formulations.

Chemical Composition and Structure
Rosa Rubiginosa Seed Oil contains a variety of bioactive compounds that contribute to its beneficial effects on the skin. The specific composition includes:

Essential Fatty Acids: Including linoleic acid (omega-6) and alpha-linolenic acid (omega-3), which help maintain skin barrier function and hydration.
Vitamin A: Provides regenerative and anti-aging benefits, promoting skin cell turnover and collagen production.
Vitamin C: Known for its strong antioxidant properties and role in collagen synthesis.
Vitamin E: Offers antioxidant protection and helps to stabilize the oil.
Carotenoids: Including beta-carotene, which provide antioxidant protection and contribute to skin health.
Sterols: Help improve skin barrier function and provide anti-inflammatory effects.
Physical Properties
Rosa Rubiginosa Seed Oil typically appears as a light to dark amber liquid with a slightly nutty aroma. It is easily absorbed into the skin, making it suitable for various cosmetic formulations.

Cosmetic and Personal Care Applications
Regenerative: The oil promotes skin cell regeneration, helping to repair and rejuvenate the skin.

Antioxidant Protection: The presence of vitamins A, C, and E, along with carotenoids, helps protect the skin from environmental stressors and free radical damage.

Moisturizing: The essential fatty acids in the oil help maintain skin hydration and improve skin barrier function.

Anti-Aging: The regenerative and antioxidant properties help reduce the appearance of fine lines and wrinkles, promoting a youthful complexion.

Brightening: Vitamin C helps brighten the skin and reduce the appearance of dark spots and hyperpigmentation.

Anti-Inflammatory: The oil’s anti-inflammatory compounds help reduce redness and swelling, providing relief for conditions like eczema and rosacea.

Environmental and Safety Considerations

Rosa Rubiginosa Seed Oil is generally considered safe for use in cosmetic and personal care products. It is well-tolerated by most skin types, including sensitive skin. The extraction process is environmentally friendly, utilizing sustainable agricultural practices. However, as with all botanical ingredients, it should be patch-tested before use, especially for those with sensitive skin.

Cosmetics - INCI Functions


Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
