Ingredient review
Sassafras Bark Extract
INCI: SASSAFRAS OFFICINALE BARK EXTRACT
Sassafras Bark Extract may offer astringent and soothing benefits, but its use is limited by safety concerns and lack of robust research.
In plain English
Sassafras Bark Extract comes from the bark of the sassafras tree. In skincare, it is sometimes added to help tighten pores and calm redness. However, the extract contains a compound called safrole, which has raised safety flags in the past. Most modern cosmetic products use a safrole-free version or avoid it altogether. It is not a common or well-studied ingredient, so its benefits are not strongly backed by science.

What it is
Sassafras Bark Extract is a natural plant extract obtained from the bark of the sassafras tree (Sassafras officinale or Sassafras albidum). It has been used traditionally for its aromatic and medicinal properties.
How it works
In cosmetics, sassafras bark extract is thought to work as an astringent, meaning it can help tighten skin and reduce the appearance of pores. It also has anti-inflammatory properties that may calm irritated skin. However, the exact mechanisms are not well-documented in modern skincare science.
Pros
Natural astringent
May help reduce excess oil and tighten pores, which can be beneficial for oily skin types.
Soothing potential
Contains anti-inflammatory compounds that could help calm minor redness or irritation.
Cons and cautions
Safety concerns
The extract naturally contains safrole, which has been restricted in some countries due to potential toxicity. Always check if the extract is safrole-free.
Weak evidence
There is very little modern research supporting its effectiveness in skincare, so benefits are largely anecdotal.
Best for

Use caution if
- Individuals with sensitive or reactive skin
- Anyone with a known allergy to sassafras or related plants
