Our take
Is Diatomaceous Earth a Good Ingredient?
Fair: Offers basic oil absorption and mild polishing, but effects are mainly cosmetic with limited evidence for lasting skin changes. Particles can be abrasive and may trigger irritation, especially on sensitive or over‑exfoliated skin.
What it does
Skin Benefits
Minimizes surface shine and buffs away flaky buildup for a smoother feel. May make pores appear less congested by lifting debris from the surface.
Where you'll find it
Uses in Skincare & Cosmetics
Featured in masks, powder cleansers, exfoliating scrubs, and dry shampoos to curb surface glare and add a fine polishing texture.
Before you use it
Safety
Mechanical exfoliation can cause redness or micro‑irritation; use gently and avoid compromised skin. Avoid inhaling the fine powder during application. Patch test if you’re prone to irritation.
