What it is
Pumpkin seed extract is a natural oil or extract derived from the seeds of the pumpkin plant (Cucurbita pepo). It contains vitamin E, zinc, essential fatty acids (like linoleic acid), and phytosterols.
How it works
The antioxidants in pumpkin seed extract, such as vitamin E, neutralize free radicals that can cause premature aging. The fatty acids help reinforce the skin's natural barrier, reducing moisture loss and keeping skin soft. Zinc and other minerals may help calm irritation and support a balanced complexion.
