Pumpkin Seed Oil
Pumpkin Seed Oil is rated 2–3 on the comedogenic scale. Published ratings for it disagree, so it sits across the 2-to-3 range, and the 3 end is the one to plan around if your skin breaks out easily.
An oil rich in zinc and antioxidants, used to lift, firm, and hydrate the skin.

What a 2–3 means in practice
Three is the tipping point on this scale. It does not usually cause an immediate spot, but it is where a slow build-up inside the pore starts to show up over weeks in a leave-on product.
Two things change what this number is worth. Ingredients are listed in descending order of concentration, so pumpkin seed oil near the top of a label matters far more than pumpkin seed oil at the bottom. And the rating describes the raw ingredient on its own. A 2006 review in the Journal of the American Academy of Dermatology found that a rating for a single ingredient does not reliably predict how a finished formula behaves on human skin. The full story of the scale is here.
Common questions
- Is pumpkin seed oil comedogenic?
- Pumpkin Seed Oil is rated 2–3 on the comedogenic scale. Published ratings for it disagree, so it sits across the 2-to-3 range, and the 3 end is the one to plan around if your skin breaks out easily.
- Is pumpkin seed oil non comedogenic?
- No. Pumpkin Seed Oil is rated 2–3 on the comedogenic scale, which is the moderate risk band. That is a published rating for the ingredient rather than a verdict on any product containing it.
- What is pumpkin seed oil's comedogenic rating?
- 2–3 out of 5. It is classed as Natural Oil / Oils (High in linoleic acid).
