Ingredient review
Sweet Clover Extract
INCI: Melilotus Officinalis Herb Extract
A gentle botanical extract with soothing potential, but limited clinical evidence for specific skincare benefits.
In plain English
Sweet clover extract comes from a flowering plant often used in traditional medicine. In skincare, it's added to help calm redness and irritation, thanks to natural compounds like flavonoids and coumarins. It's generally very mild and unlikely to cause problems, but it's not a powerhouse ingredient—think of it as a supportive helper in soothing formulas.

What it is
An herbal extract obtained from the aerial parts of Melilotus officinalis, a plant in the Fabaceae family. It contains flavonoids, coumarins, and phenolic acids that contribute to its antioxidant and anti-inflammatory activity.
How it works
The flavonoids and coumarins in sweet clover extract are thought to reduce the activity of pro-inflammatory enzymes and scavenge free radicals, which can help calm irritated skin and protect against environmental stressors.
Pros
Gentle and soothing
Sweet clover extract is very mild and unlikely to cause irritation, making it a safe choice for sensitive skin types.
Antioxidant support
It provides free radical protection, which can help defend skin against daily environmental damage like pollution.
Cons and cautions
Limited evidence
Most research on sweet clover's anti-inflammatory effects is from lab or animal studies, not large human trials on skin.
Subtle effects
As a supporting ingredient, it's unlikely to deliver dramatic results on its own and works best in combination with other soothing agents.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle, plant-based soothing ingredients
Use caution if
- Individuals with known allergy to Fabaceae (legume) plants
- Anyone seeking strong, clinically proven anti-inflammatory effects
