Astaxanthin，AXN

Astaxanthin, a naturally occurring ketocarotenoid, stands out as one of the strongest antioxidants known to science, far surpassing vitamins C and E in neutralizing free radicals. Unlike many antioxidants, its unique molecular structure allows it to span cell membranes, providing comprehensive protection against oxidative stress—whether from UV radiation, pollution, or internal aging processes.​In cosmetic applications, astaxanthin is prized for its ability to address multiple skin concerns at once. It works to reduce the appearance of fine lines, boost collagen production, and calm inflammation, while also shielding skin from environmental damage. Its lipid-soluble nature ensures optimal absorption, delivering visible results without irritation, even for sensitive skin types.

Key Functions​of Astaxanthin

Superior Antioxidant Protection: Neutralizes free radicals 500x more effectively than vitamin E, defending skin from oxidative damage.​

Anti-Aging Efficacy: Stimulates collagen synthesis to reduce wrinkles and improve skin elasticity.​

Anti-Inflammatory Action: Calms redness, soothes irritation, and alleviates sensitive skin conditions.​

UV Damage Repair: Mitigates photoaging caused by sun exposure, including dark spots and rough texture.​

Radiance Boost: Enhances skin’s natural glow by improving texture and evening out tone.​

Mechanism of Action​ of Astaxanthin

Astaxanthin exerts its effects through multiple pathways:​

Free Radical Scavenging: Its conjugated double bonds and unique ring structure trap and neutralize reactive oxygen species (ROS), preventing them from breaking down collagen and elastin.​

Cell Membrane Protection: Unlike water-soluble antioxidants, astaxanthin embeds itself in lipid-rich cell membranes, forming a protective barrier against oxidative stress from both inside and outside the cell.​

Inflammation Regulation: Inhibits pro-inflammatory cytokines (e.g., TNF-α, IL-6) and reduces NF-κB activation, calming redness and swelling at the cellular level.​

Collagen Preservation: Blocks matrix metalloproteinases (MMPs)—enzymes that degrade collagen—while stimulating fibroblasts to produce new collagen fibers.​
