INCI: Ictasol
Ictasol is a traditional ingredient used to soothe and draw out impurities, but it has a strong odor and may irritate sensitive skin.
In plain English
Ictasol is a thick, tarry substance made from a type of rock called shale oil. In skincare, it's used to help calm irritated skin and 'draw out' things like splinters or minor infections. It has a very strong, smoky smell and can be messy to use, so it's not for everyone.

What it is
Ictasol is a sulfonated shale oil, meaning it's processed to be water-soluble. It's a dark, almost black, viscous liquid with a characteristic strong odor.
How it works
Ictasol works by mildly irritating the skin, which increases blood flow to the area. This helps to bring impurities to the surface and soothe inflammation. It also has mild antibacterial and anti-inflammatory properties.
Pros
Effective drawing agent
Traditionally used to help bring splinters, thorns, and minor infections to the skin's surface, making them easier to remove.
Soothing properties
Can help calm inflamed skin and reduce redness associated with minor irritations.
Cons and cautions
Strong odor
Has a very distinct, smoky, and tarry smell that many find unpleasant and can linger on the skin.
Messy application
The dark, thick consistency can be messy to apply and may stain clothing, towels, and bedding.
Best for
