Ectoin

What it does

Ectoin protects skin cells from osmotic stress and environmental stressors by stabilizing cell membrane proteins. It strengthens the skin barrier and reduces inflammation, making it particularly effective for calming irritated or compromised skin. Often derived from halophilic bacteria, it works both as an immediate soother and a long-term skin resilience builder.
