Benefits of Pumpkin Seed Oil

Pumpkin seed oil has a beautiful deep orange colour, perfect for autumn and for your skin at this time of year. Pumpkin can help your skin transition from the summer to the winter by mitigating the effects of the sun on your skin and helping to protect it through the winter.

Pumpkin seed oil, derived from the seeds of Cucurbita pepo seeds, is rich in nutrients and has many beneficial effects on the skin. It is rich in linoleic, oleic and palmitic fatty acids, vitamin A, tocopherols, zinc, carotenoids and sterols. It has excellent anti-oxidant activity, assists in wound healing, nourishes and protects the skin.

The major lipids found in the skin are: ceramides (around 50%), cholesterol (25%) and fatty acids (10-20%). In a study of Caucasian women, the level of ceramide 1 in the stratum corneum (the outermost layer of the skin in the epidermis) was found to be 40% lower in winter compared to summer. This lower level of  ceramides in the skin during the winter months could explain the increase in dry skin at this time of year. With the use of a lotion containing oils with high levels of linoleic acid, over a 4 week period, the ceramide 1 levels were increased back to almost summertime levels. The oils used in this study were sunflower seed oil and borage seed oil, however as pumpkin seed oil is higher in linoleic acid levels than these oils, it is likely that pumpkin seed oil would also have this effect.

We use pumpkin seed oil in our Nourishing Body Oil.
