Ingredient review
Bloodroot Extract
INCI: Sanguinaria Canadensis Rhizome/Root Extract
Bloodroot extract may offer antimicrobial benefits for acne-prone skin, but it can be irritating and is not well-studied for cosmetic use.
In plain English
Bloodroot extract comes from the root of a North American plant. In skincare, it's sometimes added to help fight bacteria that can cause acne. However, it can also be irritating, especially for sensitive skin, and there isn't a lot of research on how well it works in lotions or cleansers. Think of it as a potentially helpful but strong ingredient that needs careful handling.

What it is
Bloodroot extract is a natural ingredient derived from the rhizome (underground stem) and roots of the Sanguinaria canadensis plant. It contains compounds like sanguinarine, which give it antimicrobial and anti-inflammatory properties.
How it works
In a cosmetic product, bloodroot extract works by disrupting the cell walls of certain bacteria, including those linked to acne. It may also help calm redness and irritation, though this effect is less consistent. Because it can be strong, it's usually used in small amounts and often combined with soothing ingredients.
Pros
Natural antimicrobial
Bloodroot extract may help reduce acne-causing bacteria on the skin, offering a plant-based option for blemish control.
Potential soothing effect
Some compounds in bloodroot have anti-inflammatory properties that could help calm red or irritated spots.
Cons and cautions
Irritation risk
Bloodroot extract can cause stinging, redness, or peeling, especially for those with sensitive or compromised skin barriers.
Limited cosmetic research
Most studies focus on oral or medical uses, not topical skincare, so its benefits and risks in cosmetics are not well established.
Best for
- People with occasional breakouts looking for a natural antimicrobial
- Those with oily skin who tolerate botanical extracts well
Use caution if
- Anyone with sensitive, reactive, or eczema-prone skin
- Pregnant or nursing individuals (due to lack of safety data)
Usage tips
Safety summary
Bloodroot extract is considered safe for cosmetic use at low concentrations, but it carries a moderate risk of skin irritation. It should be avoided by those with sensitive skin, allergies to plants in the poppy family, or during pregnancy due to insufficient safety data.
Research notes
Research on bloodroot extract in skincare is limited. Most evidence comes from in vitro studies showing antimicrobial activity against acne bacteria and some anti-inflammatory effects. Human studies on cosmetic formulations are scarce, so its efficacy and safety profile remain emerging.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products, lower in rinse-off formulations
- Regulatory status
- In the US, bloodroot extract is generally recognized as safe for use in cosmetics at low concentrations, but it is not specifically approved by the FDA for any medical claims. The EU CosIng database lists it as a cosmetic ingredient with no specific restrictions, though it advises caution due to potential irritation.
- Common uses
- Facial cleansers, Spot treatments, Masks
- Environmental note
- Bloodroot is a wild plant native to North America. Overharvesting for commercial use could impact natural populations, so look for sustainably sourced or cultivated extracts.
Good to know
- Bloodroot is also known as Sanguinaria, and its red sap was historically used as a dye by Native Americans.
- This ingredient is not the same as 'blood root' used in some traditional medicines—cosmetic use is different and less studied.
