yes maybe you could darren ... it would work on the outside as it does inside, a bit like hemp oil probably. Although if you did it both ways, it would work better.

Pumpkin seed oil has significant benefits for skin health and skin care. With powerful antioxidants, and essential fatty acids, it appears that adding pumpkin seed oil to your skin care regimen will help you retain moisture, maintain normal cell structure, and keep your skin looking and feeling healthy.
Pumpkin seed oil is especially high in the gamma-tocopherol form of Vitamin E, which is a powerful antioxidant.
Vitamin E has been shown to have a wide range of skin benefits. Vitamin E has been shown to reduce the amount of scarring from wounds, and has been shown to diminish the appearance of stretch marks on the skin. Also, it has been shown to decrease the effects of psoriasis, and to diminish the redness associated with erythema, which is one symptom of rosacea.
Aside from the high levels of Vitamin E found in pumpkin, there is also a high level of oil content (as high as 50%).
The four fatty acids which comprise 98% of pumpkin seed oil are palmitic, stearic, linoleic, and oleic acids.
Palmitic acid works to promote natural oil regeneration. Oil is an important component for the skin to retain its protective barrier.
With too little oil, the skin will crack and bleed; opening it to a greater risk of infection and disease.
Stearic acid acts primarily as a lubricant. It allows the skin to retain the proper moisture balance vital for good health (and good looks).
Linoleic acid is an essential fatty acid, which means our bodies don’t manufacture it, and so we must ingest it in our diets.
Linoleic acid is one step for the manufacture of prostaglandins, which decrease inflammation in the body. Linoleic acid helps maintain smooth skin, and will help repair flaky, itchy, or rough skin.
Oleic acid is the final fatty acid found in pumpkin seed oil. It works to replenish and maintain skin’s moisture and lubrication. It is an Omega 9 acid and has similar health benefits (both general and to the skin) as the more well-known Omega 3 and Omega 6 essential fatty acids.
