What it is
A natural extract derived from the peel and seeds of the grapefruit (Citrus grandis), rich in flavonoids, vitamin C, and limonoids.
How it works
It provides antioxidant protection by donating electrons to neutralize free radicals, and its antimicrobial activity comes from compounds like naringin and limonene that can disrupt bacterial cell membranes on the skin's surface.
Pros
Gentle antioxidant
Provides free radical protection without the irritation common with stronger antioxidants like pure vitamin C.
Natural antimicrobial
May help reduce surface bacteria, which can be beneficial for acne-prone skin when used in cleansers or toners.
Cons and cautions
Potential photosensitivity
In high concentrations, citrus extracts can increase sun sensitivity, though this is rare at typical skincare levels.
Allergen risk
Citrus extracts can cause allergic reactions in sensitive individuals, so a patch test is recommended.
Best for
- Anyone looking for a gentle antioxidant boost
- People with oily or combination skin who want a natural antimicrobial ingredient
Use caution if
- Those with known citrus allergies
- Individuals with extremely sensitive or reactive skin should patch test first
