Science
Mechanism of Action
Primarily attributed to its high astaxanthin content, Haematococcus Pluvialis Oil acts as a robust antioxidant, actively neutralizing detrimental free radicals that contribute to premature skin aging and lipid peroxidation from UV radiation. It exhibits significant anti-inflammatory properties by suppressing pro-inflammatory cytokines and reducing mediators such as inducible nitric oxide (iNOS) and cyclooxygenase (COX-2), thereby soothing irritated and inflamed skin. The oil provides photoprotection, defending against UV-induced damage, augmenting sunscreen SPF values, preventing UV-induced immunosuppression, and decreasing erythema. It supports dermal structure by inhibiting collagen-degrading enzymes (MMP-1, MMP-3, and elastase/MMP-12), increasing endogenous collagen content, and stimulating collagen synthesis for enhanced elasticity, firmness, and reduced wrinkle depth. Furthermore, it boosts skin hydration by upregulating aquaporin-3 (a key water transport protein) and minimizing transepidermal water loss (TEWL), fortifying the skin's natural moisture barrier for a smoother, plumper, and more radiant complexion. It also targets hyperpigmentation by suppressing melanin synthesis, mitigating oxidative triggers for melanin production, calming post-inflammatory responses, and inhibiting tyrosinase activity. Additionally, the oil contributes to wound healing by accelerating the process and increasing expression of healing markers like collagen type I α 1 (Col1A1) and basic fibroblast growth factor (bFGF), while supporting skin barrier repair and protection.
Research
Clinical Evidence
High confidenceOptimal topical percentages typically range from 0.1% to 2%.
Key findings
- 01 Astaxanthin extracted from Haematococcus pluvialis significantly increased the SPF value in sunscreens, demonstrating enhanced photoprotection.
- 02 Showed improvements in skin wrinkle (crow's feet), age spot size (cheek), elasticity (crow's feet), skin texture (cheek), and moisture content (cheek) in 30 healthy female subjects over 8 weeks.
- 03 Resulted in a 106.67% elevation in skin moisture content of the left outer canthus after two weeks of application in participants with dried and mixed skin, with observed anti-wrinkle effects.

The Formula
Formulation
Stability
The primary active component, astaxanthin, exhibits poor water solubility and can be chemically unstable. Temperature is a critical factor, with stability maintained between 70–90 °C in certain edible oils, but content is reduced at 120 °C and 150 °C. Formulators commonly utilize advanced delivery systems such as liposomes, particulate systems, inclusion complexes, emulsions, and films to enhance its stability, bioavailability, and overall efficacy. Prolonged extraction times or certain microalgae extract compositions can hinder free astaxanthin stability.
Safety
Safety Profile
Haematococcus Pluvialis Oil is generally regarded as safe for topical application in cosmetic products, with typical usage concentrations ranging from 0.1% to 2%. While no specific health claims or therapeutic indications for topical astaxanthin have been approved by the FDA or EFSA, astaxanthin-rich oleoresin has been accepted by the FDA as a food colorant in animal feed and by the European Commission as a food dye and food supplement. Side effects are generally uncommon, though mild irritation, redness, or allergic reactions can occur, particularly in individuals with allergies to marine products. A preliminary patch test is advised prior to widespread use.
