NATURE’S MOST
ADVANCED SKIN
RECOVERY SYSTEM

Using computational metabolomics, we’ve spent 10 years decoding marine organism defense pathways, pinpointing the molecules that repair, restore and protect, how they act, and the optimal concentrations for human skin.

Inflammaging. The Root Cause of Premature Aging.

Inflammaging. The Root Cause of Premature Aging.

Behind fine lines and loss of firmness lies a deeper process: chronic, low-grade inflammation known as inflammaging. Triggered by cumulative UV exposure, stress and environmental exposure, it quietly breaks down collagen and weakens your skin’s natural defenses over time.

Sirenas Complex AQ, built from marine bioactives, targets this cycle at the cellular level. It penetrates to rebalance inflammation, actively neutralize free radicals, and strengthen skin barrier function before surface damage appears-training your skin to adapt and resist stress over time.

Most skincare addresses surface symptoms. We target the root cause of premature aging.

OUR SCIENCE + TECHNOLOGY

Discovery to Innovation

For over 500 million years, marine life has thrived under relentless sun, salt, and stress. Their secret is biochemical resilience—bioactive compounds refined by evolution into nature’s most advanced recovery systems. Using computational metabolomics, we’ve spent 10 years decoding these defense pathways, pinpointing the molecules that repair, restore and protect, how they act, and the optimal concentrations for human skin. This evolutionary intelligence now powers every Terns formula through the Sirenas Complex-our breakthrough ingredient that brings the ocean’s adaptive power to human skin.
