Imagine an organism that lives in salt lakes and deserts, where water is scarce and the sun is harsh. To survive, it makes a protective molecule called ectoin. Today that same molecule is one of skincare's most promising hydrators. Here is what the science says, with every source linked.
Quick facts
- What it is: a natural protective molecule made by microorganisms in extreme environments
- On a label: Ectoin or Ectoine
- Discovered: 1985
- Best known for: helping skin hold on to moisture and feel calm
How ectoin works
Ectoin surrounds cells with a protective "water shell." This helps protect cell membranes from dryness and the irritation that can follow. Its hydrating and soothing properties have been studied since it was discovered in 1985. (Kauth & Trusova, Dermatology and Therapy, 2022)
What the research says
- Systematic review (2022): researchers reviewed the clinical studies on ectoin creams for very dry, sensitive skin. Formulas with 5.5 to 7% ectoin improved skin dryness and comfort, and were well tolerated by both children and adults. (Kauth & Trusova, 2022)
- Gentle enough for sensitive skin: the same review found ectoin was as effective as dexpanthenol, a classic soothing ingredient, in helping skin stressed by strong skincare actives. (Dermatology and Therapy, 2022)
Ectoin vs. hyaluronic acid: hyaluronic acid draws water into the skin. Ectoin helps the skin keep it. That is why they work so well together.
Why we chose ectoin for Sana Raíz
