Différence entre rose de Damas et rose musquée.

Differences between Damask Rose and Rosehip.

The rose is the oldest flower, rich in symbolism. It is often referred to as the queen of flowers. At present, over 200 species of roses and more than 18,000 cultivars of the plant have been identified. Among the different varieties belonging to the family of Rosaceae, the Damask rose and the musk rose are two species used in various forms in skincare. The Damask rose is present in the form of essential oil and hydrosol, while the musk rose yields a vegetable oil.

Damask Rose and Rosehip, different origins.

Botanically referred to as "Rosa canina", the rosehip is a species of thorny shrubs related to the wild rose. It is found in the wild in South America, specifically in the Andean valleys of Chile. Its flowers are white and have between 5 to 9 petals.

The Damask rose (Rosa damascena) is originally from the Middle East (Iran). Today, it primarily thrives in Bulgaria (the world's leading exporter), Morocco, and the mountains of the Isparta region in Turkey. It has been present in France since the Middle Ages, brought back by the knight Robert DE BRIE upon his return from the crusades in the mid-13th century. Unlike the musk rose, the flowers are pink and have more petals.

Damask rose essential oil and rosehip vegetable oil, two distinct cosmetic ingredients.

These two compounds differ in two main aspects:

  • The extraction process:

    Thevirgin rosehip oil is extracted byfirst cold pressing of the seedsharvested from the fruits of the plant, followed by a cellulose paper filtration. It presents itself as an oily liquid of an orange-red color with a subtle rose scent. Its texture is quite greasy and it is very sensitive to oxidation.

    TheDamask rose essential oil is obtained following a double distillation by steam distillation. This process yields a low return: 5 tons of petals only produce 1 kg of essential oil. The first distillation is carried out using the petals. These are placed in a still and then traversed by steam, which is subsequently cooled in a condenser and collected in liquid form. The essential oil, less dense than the water used for extraction, floats on the surface. This water is nothing other than the hydrosol. The second distillation is simply the redistillation of the Damask rose hydrosol obtained previously.

  • The biochemical composition:

    Therosehip oil, like the majority of vegetable oils, contains fatty acids. The most significant in proportion are linolenic acid, linoleic acid, oleic acid, palmitic acid, and stearic acid. Furthermore, it also contains carotenoids (transretinoic acid), vitamins (E and K), as well as squalene.

    TheDamask rose essential oil contains aromatic molecules. It is primarily composed of monoterpenic alcohols(citronellol, nerol, geraniol, linalool). These molecules make up about 70% of the essential oil, with the majority being citronellol, which can be present up to 50%.

Rosehip and Damask rose, two allies for mature skin.

On one hand, therosehip vegetable oil is recognized for its antioxidant action. Rich in vitamin E, it protects the skin from free radicals. As a reminder, these arereactive oxygen speciesproduced naturally by the body. However, when cells are faced with astress, they produce them in anexcessivemanner. The sources of stress are numerous, the main ones being exposure to UVA, pollution, smoking, a diet too rich in fats and/or sugars. Free radicals are particularly unstable molecules due to theirsingle electron. They tend to react with other molecules to form apair of electrons, and then causedamage to cells, DNA, and proteins in the body. Aging is thus accelerated and wrinkles appear on the skin surface. Therosehip oil is therefore a choice ally to prevent premature skin aging. Moreover, the presence of trans-retinoic acid in rosehip oil acts on the overproduction of melanin and diminishes the appearance of pigment spots on the skin surface that appear with age.

On the other hand, theDamask rose essential oil is regenerative and firming. The monoterpenic alcohols it contains (citronellol, nerol, and geraniol) tighten the tissues, thus limiting the skin sagging that appears over the years. Moreover, researchers have demonstrated its ability to stimulate the expression of the collagen-I gene. In other words, this essential oil is a true tissue and cellular regenerator.

The rosehip vegetable oil at Typology.

Ourrosehip vegetable oilis 100% virgin and certified organic. It has been cold-pressed from rosehip seeds grown and harvested in Chile. It also makes up theradiance facial scrub. This is a melting gel with micro-grains of apricot kernels, which unclogs pores and promotes cell renewal, for smooth skin, an even and luminous complexion.

In which Typology skincare product can one find the essential oil of Damask rose?

Ourfirming tonercontains Damask rose extract (a blend of essential oil and hydrosol) combined with0.1% of retinol, the ultimate skin-tightening active ingredient. This lotion, with a pH level as acidic as the skin, rebalances the skin's pH after each cleansing. It also helps to remove the lime scale residues present in the water during cleansing. Rich in firming active ingredients, it reduces the appearance of wrinkles and fine lines, and fights against skin sagging.

To apply it, soak a cotton pad with the firming lotion and then sweep it across your entire face, which should be previously cleaned, avoiding the eye area, only in the evening.

Note :We advise against its use for sensitive and reactive skin types, as well as for pregnant and/or breastfeeding women.
