What it is
A natural extract derived from the fruit of Rubus crataegifolius, a species of raspberry native to East Asia. The fruit is rich in anthocyanins, ellagic acid, and other polyphenols that give it antioxidant and anti-inflammatory properties.
How it works
The polyphenols in the extract neutralize free radicals, reducing oxidative stress on skin cells. This helps protect collagen and elastin fibers from premature breakdown. The extract also has mild astringent and soothing effects, which can help calm minor redness and support a balanced complexion.
Pros
Rich in protective antioxidants
Contains anthocyanins and ellagic acid that help neutralize free radicals, potentially reducing signs of premature aging from sun and pollution.
Gentle and soothing
Unlikely to cause irritation, making it a safe option for sensitive skin types when used at typical concentrations.
Cons and cautions
Limited research on topical use
Most studies focus on oral consumption of the fruit; direct evidence for skincare benefits is still emerging, so results may vary.
Low concentration in formulas
Often used as a supporting ingredient, so its effects may be subtle and not as dramatic as more potent antioxidants like vitamin C.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- Those with normal, combination, or dry skin who want extra environmental protection
Use caution if
- Individuals with a known allergy to raspberries or related berries should patch-test first
