Rosehip Oil

Brief Description

Rosehip Oil is a cold-pressed oil extracted from the seeds of rose bushes, primarily Rosa canina. Rich in essential fatty acids, vitamins, and antioxidants, it is renowned for its ability to hydrate, repair, and rejuvenate the skin. Rosehip Oil is a versatile ingredient used in anti-aging, brightening, and moisturizing formulations.

INCI Name

Rosa Canina Fruit Oil

Appearance

Golden to reddish-orange oil with a light, earthy aroma.

Formulation Guidance

  • How to Formulate:
    • Used in anhydrous formulations or added to the oil phase of emulsions.
    • Works well with other carrier oils, butters, and essential oils.
    • Avoid heating above 40°C to preserve its bioactive compounds.
  • Usage Rate: 1–20%, depending on the product type and desired benefits.

Scientific Data on Efficacy

  • Benefits:
    • Contains high levels of linoleic acid and linolenic acid, which help maintain the skin barrier and prevent moisture loss.
    • Naturally rich in Vitamin A (in the form of retinoids) and Vitamin C, promoting skin repair and brightening.
    • Reduces the appearance of scars, fine lines, and hyperpigmentation.
  • Research and Studies:
    • A study published in International Journal of Molecular Sciences found that Rosehip Oil improves skin elasticity and hydration due to its high fatty acid and antioxidant content​ .
    • Research in Journal of Cosmetic Dermatology showed its efficacy in reducing post-inflammatory hyperpigmentation and scarring​ .

pH Stability Range

As an oil, Rosehip Oil does not have a pH and is stable in formulations with a wide pH range.

Solubility

Oil-soluble and should be used in oil-based formulations or emulsions.

Why to Use It in Formulations

Rosehip Oil is a natural powerhouse for skin rejuvenation. Its unique combination of essential fatty acids, antioxidants, and vitamins makes it ideal for targeting aging, scars, and uneven skin tone. Its lightweight texture allows it to absorb easily into the skin without clogging pores, making it suitable for all skin types, including oily and acne-prone skin.

Stability Considerations

Rosehip Oil is sensitive to oxidation due to its high unsaturated fatty acid content. Use antioxidants like Vitamin E to prolong shelf life and store in dark, airtight containers away from heat and light.

Possible Alternatives

  • Sea Buckthorn Oil: Offers similar antioxidant and skin-repairing benefits but with a more intense orange color.
  • Marula Oil: A lightweight oil with excellent moisturizing properties and a longer shelf life.
  • Argan Oil: Provides hydration and antioxidant benefits but lacks the Vitamin A content of Rosehip Oil.
