The oil essentially provides excess sebum that blocks pores and creates the ideal environment for acne-causing bacteria.

But knowing pumpkin seed oil's comedogenic rating provides an important caution for those prone to congestion or sensitivity. As with any new skin care ingredient, patch testing for allergies is critical. Make sure pumpkin seed oil is safe for your skin type before including it in your daily regimen!
