Ectoin

EctoinHydrator

A tiny water-binding molecule from extreme-environment bacteria — hydrating and mildly calming.

What it does

The studies on people mixed it with other ingredients, so they don’t show what ectoin does alone.

The evidence, graded

strongOne application of a ceramide cream lowered water loss through the skin, measured from two hours and held to 24 hours, and raised skin hydration over the same day. Hyaluronic acid creams improved skin hydration and elasticity when measured at 30 and 60 days. Neither source Drop has read measured how long barrier repair takes, so Drop sets no barrier-repair window.Pavicic 2011 · Journal of Drugs in Dermatology ↗
strongIn an observer-blind trial in 70 children aged 2 to 18 with mild to moderate atopic dermatitis, a cream with 1% ectoine and 0.1% hyaluronic acid improved severity and itch more than its plain base cream over 4 weeks. Mild skin side effects were more common with it: 23.5% of children, against 5.7% on the base cream.Alexopoulos 2023 · Pediatric dermatology ↗

Graded per the methodology: strong · moderate · emerging · expert consensus. A weak source on a strong claim gets the weaker label.
