Black Cohosh Extract
INCI: CIMICIFUGA SIMPLEX LEAF/STEM EXTRACT
A gentle botanical extract with antioxidant potential, but research on topical benefits is still limited.

In skincare, it is added for its ability to help calm the skin and fight damage from environmental stressors like pollution. Think of it as a mild helper that may support your skin's natural defenses, but it's not a powerhouse ingredient on its own.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
An extract derived from the leaf and stem parts of the Cimicifuga simplex plant (a type of black cohosh), typically obtained through solvent extraction and then incorporated into cosmetic formulations.
How it works
It provides antioxidant activity by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells. It may also have mild anti-inflammatory effects by reducing the activity of certain enzymes involved in skin irritation.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for most skin types, including sensitive skin.
Antioxidant support
Helps protect skin from free radical damage, which can contribute to premature aging over time.
Cons and cautions
Limited research
Most studies focus on oral use of black cohosh for menopause; topical skincare benefits are not well-documented in peer-reviewed research.
Low potency
As a single extract, it may not provide as strong antioxidant effects as more concentrated or well-studied ingredients like vitamin C or ferulic acid.
Best for
- People with normal to combination skin looking for gentle antioxidant support
- Those interested in botanical-based skincare routines
Use caution if
- Individuals with known allergies to black cohosh or related plants (Ranunculaceae family)
Usage tips
Safety summary
Generally recognized as safe for topical use at typical cosmetic concentrations. Rare allergic reactions are possible. Avoid use on broken or irritated skin.
Research notes
Evidence for topical benefits is primarily based on traditional use and in vitro antioxidant assays. Human clinical studies specific to skincare are lacking, so efficacy claims should be viewed with caution.
