Science
Mechanism of Action
Aristotelia Chilensis Fruit Extract exerts its effects through a rich array of powerful antioxidants, including specific anthocyanins (notably delphinidins), polyphenols, flavonoids, carotenoids, and Vitamins C and E. These compounds effectively neutralize free radicals, safeguarding the skin from oxidative stress and environmental damage, including UV exposure. The extract’s anti-inflammatory properties help to soothe skin and diminish redness, contributing to an even tone. Furthermore, it supports skin elasticity and suppleness by inhibiting collagen-degrading enzymes and promoting new collagen synthesis. It also aids in improving skin hydration, cellular repair, and regeneration, leading to a visibly brighter and more revitalized appearance.

Key findings
- 01 Oral supplementation with 60 mg daily (as an anthocyanin-standardized maqui berry extract, Delphinol) led to increased skin brightness, improved collagen content, and reduced facial redness in female participants aged 27 to 57 over an eight-week period.
- 02 A clinical study demonstrated that daily oral intake of 486 mg (162 mg three times daily) significantly reduced blood markers of free radical damage, indicative of lowered oxidative stress levels, over four weeks.
- 03 In a randomized, double-blind, placebo-controlled study, healthy Japanese women experienced significantly improved skin tone and reduced facial redness with daily oral intake of the extract, observed between 4 and 8 weeks.
- 04 In vitro testing at concentrations ranging from 25-200 µg/mL confirmed no cytotoxic effect on normal human skin fibroblast cells and exhibited a slight protective effect against UVB radiation.

The Formula
Formulation
Stability
The native maqui fruit typically presents a pH of approximately 3.90. Extraction processes have been noted to involve acidification, sometimes to pH 2. As a water-soluble ingredient, and given the pH sensitivity of its key active compounds like anthocyanins, careful pH management during formulation is essential to maintain stability and preserve the extract's color.
Safety
Safety Profile
There is no direct CIR, SCCS, or FDA topical safety status available for Aristotelia Chilensis Fruit Extract. Oral consumption of maqui berry extract up to 180 mg daily for up to three months is considered possibly safe, though comprehensive information on potential side effects requires further investigation. In vitro studies indicate no cytotoxic effects on human skin fibroblast cells at concentrations up to 200 µg/mL and confirm safety regarding heavy metal content (arsenic, cadmium, lead). While generally well-tolerated, some individuals might experience allergic reactions such as redness, irritation, swelling, hives, or rash. Given that certain antioxidants within the extract may potentially heighten sun sensitivity, the consistent use of broad-spectrum sunscreen is strongly advised when incorporating this ingredient into a skincare regimen.
