Ectoin

Ectoin is a naturally occurring extremolyte - a small protective molecule produced by microorganisms that survive in extreme environments such as high-salt lakes and deserts. Ectoin was first described in 1985, following its isolation from halophilic bacteria of the genus Ectothiorhodospira, found in Egyptian salt lakes. The name “ectoine” was derived from this genus. 

Microorganisms rely on molecules like ectoin to prevent dehydration and protect essential biological structures under constant environmental stress. It achieves this by stabilising the surrounding water environment, helping proteins, membranes, and DNA maintain their structure and function.

Ectoin is highly compatible with human skin, with studies showing it is non-irritating, well tolerated, and suitable for sensitive or compromised skin. It helps the skin retain water and maintain a stable cellular environment - supporting hydration and strengthening the skin barrier. As a result, ectoin is particularly effective at reducing redness and dryness triggered by everyday environmental stress such as UV exposure, wind, and dry air.

Beyond skincare, ectoin is used in eye drops and nasal sprays, where gentle, non-irritating protection is essential. It helps stabilise the natural moisture layer on the eye and nasal surfaces, reducing dryness and irritation caused by allergens, pollution, and dry air. This makes it particularly useful for conditions like dry eyes and hay fever.

Ectoin brings a unique, science-backed approach to hydration and protection - working at the level of water structure to support skin stability under real-world conditions. Its versatility and compatibility make it suitable across a wide range of formulations, from everyday skincare to more targeted applications.

Key benefits:

• Supports long-lasting hydration by helping skin retain water
• Reinforces the skin barrier against environmental stress
• Reduces redness and dryness from UV exposure, wind, and dry air
• Calms sensitive or compromised skin without irritation
• Suitable for advanced formulations, including eye and nasal applications
