Barrier-Support Emollient Oil Hydration & Barrier

What it is & what it does

Sunflower Seed Oil is an emollient oil typically rich in linoleic acid.
Linoleic-rich sunflower oil can support barrier lipids and reduce moisture loss, and human skin-barrier research generally favors it over oleic-acid-rich oils for irritated skin. Exact fatty-acid composition varies by cultivar.

Usage & cautions
