What is Pumpkin Enzyme?
Pumpkin Enzyme is a marketing term more than an ingredient name. On labels, it usually appears as pumpkin fruit extract or pumpkin seed oil. Products marketed as pumpkin enzyme peels or masks are popular, especially in autumn.
Pumpkin itself contains useful ingredients: antioxidants such as carotenoids and fatty acids such as linoleic acid. The claim that its enzymes exfoliate skin is much less well supported.

How Does It Work?
Pumpkin has real skincare value, but not mainly from enzymes. Its flesh and seeds provide antioxidant pigments called carotenoids, and its oil provides fatty acids like linoleic acid and vitamin E. These support skin comfort and give antioxidant protection.
The idea that pumpkin enzymes dissolve dead skin has little published support. Paula's Choice states there is no substantiated research for pumpkin enzymes as exfoliants, and notes that enzymes are unlikely to stay stable in a finished product.
When a pumpkin product does exfoliate, it is often because it also contains acids such as lactic or glycolic acid, and the exfoliation can be credited to those, not to pumpkin. If you want proven exfoliation, check for a named acid on the label.
