Vitamin C Serum: Kakadu Plum Cold Press Oil 2 oz

Ingredients: Organic Kakadu Plum Oil

Size: 2 oz

USE: Apply skin as needed. For external use only.

Description: Kakadu plums have five times the amount of antioxidants found in blueberries, as well as lesser-known antioxidants such as gallic acid, which is associated with a healthy skin barrier and restoring skin elasticity. Antioxidants fight free radicals that can lead to wrinkles, dark spots, and loose skin. Kakadu Plums have shown to have anti-inflammatory, antimicrobial, and prebiotic properties.

Research:  Kakadu Plum

Benefits: Kakadu plum (Terminalia ferdinandiana), also known as Australia's superfruit, is renowned for its exceptionally high vitamin C content—often 50–100 times higher than oranges—and rich levels of phenolic compounds (like ellagic acid and other polyphenols), which provide strong antioxidant properties.

Evidence-based benefits for skin primarily stem from its topical use in skincare products, supported by preclinical studies, in vitro research, animal models, and limited human clinical trials. While vitamin C's general skin benefits (brightening, collagen support, etc.) are well-established, Kakadu plum-specific evidence is emerging but not as extensive as for synthetic or other vitamin C forms.

Key evidence-based benefits include:

• Powerful antioxidant protection — Kakadu plum's high vitamin C and polyphenols combat free radicals and oxidative stress from UV exposure, pollution, and environmental damage, helping prevent premature aging and cell damage. Studies confirm strong antioxidant activity in extracts, with polyphenols showing enhanced effects after gut breakdown (though primarily for ingested forms; topical benefits align via direct application).
• Collagen production and skin elasticity — Vitamin C is essential for collagen synthesis, and Kakadu plum supports this, potentially improving skin firmness and reducing wrinkles. Animal studies show it inhibits matrix metalloproteinase-1 (MMP-1, which degrades collagen) and prevents collagen loss in UV-exposed skin.
• Brightening and even skin tone — It helps inhibit melanin production, fade hyperpigmentation/dark spots, and promote radiance. Some clinical evidence from product-specific trials indicates improved skin luminosity (e.g., gloss value measurements) and reduced periorbital wrinkles in human split-face studies.
• Anti-inflammatory and soothing effects — Polyphenols reduce inflammation, redness, and irritation, potentially benefiting sensitive skin or conditions like acne/rosacea.
• Potential photoprotection — A 2025 scoping review highlights strong indirect evidence (antioxidant, anti-inflammatory, cytoprotective effects) for UV protection, with one animal study showing direct photoprotective benefits, though more human trials are needed.
