Valuable / ANTIOXIDANT

Antioxidant Anti-inflammatory Anti-glycation Skin Conditioning Skin Regeneration Brightening

Science

Mechanism of Action

This ingredient functions as a robust antioxidant, neutralizing free radicals generated by environmental stressors and pollution, thereby safeguarding collagen and elastin. Its unique carotenoids, such as phytoene and phytofluene, possess anti-glycation and anti-inflammatory properties that help diminish inflammation and minimize wrinkle formation. It also supports skin regeneration and repair by promoting cell turnover, can reduce hyperpigmentation, and replenishes vital minerals like magnesium and potassium, enhancing skin immunity. As a natural source of beta-carotene, particularly 9-cis beta-carotene, it acts as a precursor to retinoids and Vitamin A, essential for optimal skin health and gene expression regulation.

Key findings

  1. 01 Topical application of a 1% Dunaliella salina extract (which includes components from Dunaliella bardawil) demonstrated significant reductions in skin glycation scores, enhanced skin resilience to irritation, mitigated inflammation, and decreased skin redness and wrinkles over 8 weeks of intense solar exposure.
  2. 02 Oral intake of Dunaliella bardawil powder (60-80 mg/day total beta-carotene, with 30-40 mg 9-cis beta-carotene) for 6 weeks resulted in a 61.3% reduction in the Psoriasis Area and Severity Index (PASI) score for patients with mild to moderate chronic plaque-type psoriasis, significantly outperforming the placebo group's 34% reduction.

Stability

Its active carotenoid components, including beta-carotene, phytoene, and phytofluene, are lipid-soluble and highly susceptible to oxidation when exposed to air and light. Formulations should therefore incorporate protective measures against these elements to maintain ingredient efficacy.

Sensitization risk Unknown

Dunaliella bardawil is designated as Generally Recognized As Safe (GRAS) by the FDA for food applications (GRN 351, GRN 276). Oral studies, including those in rats (up to 10% of diet) and human clinical trials for psoriasis, reported no significant adverse effects, changes in liver function, lipid profiles, or mucocutaneous issues. While the Cosmetic Ingredient Review (CIR) lists Dunaliella Bardawil Powder in an assessment for 'Red Algae-Derived Ingredients', a conclusive 'safe as used' or 'safe with restrictions' statement for cosmetic topical use is not available in the provided data.
