Science
Mechanism of Action
This microalgae complex operates through several sophisticated pathways to optimize skin vitality. *Dunaliella salina*, rich in beta-carotene, lutein, zeaxanthin, chlorophyll, polyunsaturated fatty acids (PUFAs), and ascorbic acid, acts as a potent antioxidant, exhibiting significant antiglycation and anti-inflammatory effects, with its peptides actively scavenging free radicals. *Nannochloropsis gaditana* provides critical cellular protection by modulating oxidative responses and apoptosis, while positively regulating genes vital for skin texture, hydration (including AQP3, Col6A1, FBN1), irritation response, DNA integrity, and age-related cellular processes (such as IL1R, PCNA, FOXO3). *Tetraselmis chuii* and *Isochrysis galbana* contribute substantial antioxidant activity; *Isochrysis galbana* further shields skin from environmental aggressors and helps reduce irritation, both containing alpha-tocopherol to inhibit lipid peroxidation. *Phaeodactylum tricornutum* enriches the blend with beneficial fucoxanthin and EPA.

Key findings
- 01 A clinical trial involving Dunaliella salina extract at a 1% concentration demonstrated a reduction in glycation scores, enhanced skin resilience to irritation, decreased inflammation, and significantly improved skin redness and wrinkle appearance over 8 weeks under intense solar exposure, compared to a placebo.
- 02 In vitro studies on Nannochloropsis gaditana extract revealed robust skin protection against induced oxidative stress, alongside a positive modulation of genes crucial for skin texture, hydration (e.g., AQP3, Col6A1, FBN1), inflammation, DNA repair, and aging pathways (e.g., IL1R, PCNA, FOXO3).
- 03 Individual Dunaliella salina micro-algae extract is generally incorporated into anti-aging, rejuvenating, and revitalizing skincare products at concentrations between 1% and 3% for its moisturizing and skin-conditioning benefits.

The Formula
Formulation
Stability
This extract is typically water-soluble. For optimal integration, components such as Dunaliella salina extract should be incorporated into the water phase of an emulsion or introduced at the final stages of the formulation process. Extraction generally involves solvents like water, alcohol, or carbon dioxide.
Safety
Safety Profile
While adverse reactions to this microalgae extract blend are generally uncommon, a preliminary patch test is recommended prior to extensive application. Individuals who are pregnant or breastfeeding are advised to consult a healthcare professional before incorporating products containing this extract. Notably, Tetraselmis chuii, a component of this blend, is recognized within the INCI listing as non-hazardous, non-infectious, and non-toxic to human health, classified under the Plantae Kingdom by the FD&C Act.
