What is "Curcubita Pepo Seed Oil" and what is its utility?

This refers to the I.N.C.I. name given to thevegetable oil from pumpkin seeds. In medicine, it is recommended for regulating prostate disorders as well as urinary infections. When applied to the skin, it provides nourishment and is particularly recommended for dry skin. Let's focus on this cosmetic ingredient with multiple virtues.

An overview of pumpkin seed vegetable oil.

Curcubita pepo is the botanical name for squash, an annual plant belonging to the Cucurbitaceae family that produces compact and voluminous fruits. Squash was one of the very first fruits brought back from America to Europe by Christopher Columbus. Originally from Central America, squashes are now cultivated all over the world.

Pumpkin seed vegetable oil is obtained by cold pressing its seeds. It is rich in fatty acids essential polyunsaturated (linoleic acid, linolenic acid), in essential monounsaturated fatty acids (oleic acid) as well as in essential saturated fatty acids (palmitic acid, stearic acid). It also contains an unsaponifiable fraction composed of phytosterols, polyphenols, vitamins (A, B2, B3 and E) and minerals (potassium, zinc).

In terms of its organoleptic characteristics, this oil is yellowto dark green in colour with reddish reflections and emits a slight pleasant odour. Being low in comedogenicity, it feels quite dry to the touch and is therefore suitable for both dry and combination skin types.

The benefits of pumpkin seed oil for the skin.

Pumpkin seed oil contains approximately 12% alpha-linolenic acids, essential fatty acids known as omega-3. These confer upon it excellent properties nourishing, making it a prime ally for dry skin. Moreover, it contains an amino acid with recognised anti-inflammatory properties, the cucurbitin. This acts on the allergic reaction by inhibiting the synthesis of histamine, a potent vasodilator that increases the capillary permeability and activates inflammatory cells. Therefore, pumpkin seed oil is recommended to soothe skin reactions and redness. Furthermore, it contains powerful antioxidants such as phytosterols that slow down skin ageing caused by the overproduction of free radicals.

The benefits of pumpkin seed oil for hair.

This ingredient is recommended for combating hair loss. Indeed, research has revealed that pumpkin seed vegetable oil is capable of inhibiting the action of the 5-alpha-reductase enzyme, which is responsible for halting hair growth and causing hair loss. Thanks to its nourishing and emollient properties, it also protects hair follicles and enhances the shine of hair fibres.

When applied topically, there are no contraindications to the cosmetic use of pumpkin seed vegetable oil. It can be used by pregnant women and young children. Sensitive to oxidation, it is best stored in a dry place, protected from light and at a temperature below 25°C.
