Ingredient review
Guava Seed Oil
INCI: PSIDIUM GUAJAVA SEED OIL
A gentle, non-greasy oil that hydrates and protects skin with essential fatty acids and antioxidants.
In plain English
Guava seed oil is pressed from the tiny seeds inside guava fruit. It's a lightweight oil that feels silky on skin, not heavy or sticky. It contains linoleic acid (an omega-6 fatty acid) and vitamin C, which help keep the skin barrier strong and defend against environmental damage. Because it's low in oleic acid, it's less likely to clog pores than some other oils.
