    Oat and colloidal oatmeal: the botanical dermatologists actually recommend

    Colloidal oatmeal is one of the few botanicals with randomized trials and mechanistic lab work supporting its use for dry, itchy and eczema-prone skin. The strongest evidence is for formulated topical products containing colloidal oat or its extracts; many studies test finished products or combination formulas rather than isolated oat constituents.

The plant sources and stability issues behind that one-letter swap are mostly documented in laboratory and oil‑chemistry studies, with little direct human testing of squalane alone.
