Dunaliella Salina Extract is a potent microalgal extract derived from the halophilic green alga Dunaliella salina. It is one of the richest natural sources of β-carotene (provitamin A), carotenoids (including lycopene, lutein, zeaxanthin), astaxanthin-like pigments, vitamins (A, C, E), minerals, amino acids, and polyphenols. This extract delivers exceptional antioxidant protection, photoprotection, brightening, anti-aging, and skin-conditioning benefits. It is widely used in premium anti-aging serums, day creams, sunscreens, brightening treatments, after-sun products, and protective moisturizers. It helps combat oxidative stress, reduce signs of photoaging, even skin tone, and promote a radiant, resilient complexion.

What is DUNALIELLA SALINA EXTRACT used for?
- Antioxidant protection: Neutralizes free radicals and protects against UV-induced oxidative damage. Frequently used in day creams, serums, and sunscreens for prevention of premature aging and environmental stress.
- Skin conditioning / Moisturizing: Improves skin softness, hydration, and barrier function. Ideal for moisturizers, serums, and masks targeting dry, dull, or mature skin.
- Brightening & tone evening: Inhibits melanin production and reduces hyperpigmentation. Common in brightening serums, spot correctors, and anti-aging products for more even, luminous skin tone.
- Photoprotection & anti-inflammatory: Supports skin defense against UV and soothes irritation. Used in after-sun care, protective treatments, and sensitive skin formulations for recovery and resilience.
Origin
Dunaliella Salina Extract is sourced from the microalgae Dunaliella salina. It is cultivated in high-salt environments (e.g., solar salt ponds in Australia, Israel, or controlled photobioreactors). The algae are grown under stress conditions (high salinity and intense light) to maximize carotenoid production, then harvested and dried. They are subsequently extracted using gentle methods such as water, glycerin, or supercritical CO₂ to concentrate β-carotene, xanthophylls, and other bioactives. This sustainable, microalgae-based process yields a red-orange to amber liquid or powder suitable for clean, vegan, and marine-inspired cosmetic formulations.

SOOTHINGSafety Profile
Dunaliella Salina Extract is considered safe for cosmetic use. It has a very low hazard rating from EWG (typically 1) and minimal concerns for irritation, sensitization, or toxicity at typical concentrations (0.1-5%). It is well-tolerated across skin types, including sensitive, with strong antioxidant and soothing properties contributing to its gentle profile. Rare allergic reactions may occur in those sensitive to algae or carotenoids. Patch testing is recommended.
