Benefits of Lithothamnion Calcareum Extract

A sustainably harvested marine algae extract naturally rich in calcium, magnesium and trace minerals.

• Marine Mineral Source: Naturally supplies calcium, magnesium and dozens of trace elements to condition skin.
• Barrier Support (Appearance): Helps skin look replenished, resilient and healthy — a natural complement to ceramides.
• Soothing Comfort: Valued in formulas for sensitive, reactive-feeling skin for a calm, comfortable finish.
• Replenishing: Helps remineralize and condition skin that looks dull or depleted.
• Naturally Derived & Sustainable: Sourced from responsibly harvested calcareous marine algae (maerl).

How It Works

As it grows, the Lithothamnion algae accumulates calcium carbonate and magnesium along with a broad spectrum of trace minerals (such as zinc, iron and manganese) from seawater, concentrating them in its calcified structure. Milled into a fine extract, it delivers this natural mineral matrix to the skin’s surface, where it conditions, helps replenish the look of depleted skin, and supports the appearance of a comfortable, well-balanced barrier.

Formulating with Lithothamnion Calcareum Extract

Lithothamnion Calcareum Extract is typically incorporated into the water phase and used at low to moderate levels in creams, lotions, masks and soothing barrier treatments. It pairs naturally with barrier lipids (ceramides, cholesterol, fatty acids) and humectants in remineralizing, “marine” and sensitive-skin positioning. Adjust to the desired mineral feel and observe good manufacturing and preservation practice.
