This unique compound seems to do it all. “Ectoin works to provide a protective shield for the skin,” board-certified dermatologist Marissa Garshick, MD, tells Allure. “By protecting against external stressors, it also offers protection against blue light and pollution.” Here’s why ectoin is getting such incredible buzz from experts and dermatologists.

What Exactly Is Ectoin?

Ectoin is an amino acid compound derived from single-cell bacteria found in some of the harshest environments on earth. “Ectoin was discovered in the harsh conditions of salt lakes and deserts, where extremophilic microorganisms flourish by producing substances that protect them from these intense environments,” says skincare guru Kate Somerville. “Ectoin is a type of amino acid, known scientifically as an ‘extremolyte,’ which acts to shield these organisms by stabilizing their proteins and cell membranes against extreme heat, cold, and dryness.”
Protective Qualities

Those protective qualities are what makes Ectoin so useful as a skincare ingredient. “It protects organisms against dehydration, extreme temperatures and a host of other environmental factors by providing a natural protective component on the outer layer of cells,” Dr. Stefani Kappel board-certified dermatologist Dr. Stefani Kappel tells CNN.
UVA Protection and Wound Healing

Moisturizing Superstar

Because it reduces the impact of the sun’s harmful rays, it helps fight inflammation, which means less crepe-y and overall smoother skin.”

Ectoin works nicely with other ingredients, and can soothe any side effects from retinol. “Ectoin acts as a great team player with other ingredients,” board-certified dermatologist Dr. Nowell Solish tells CNN. “It works well with other moisturizing ingredients including humectants like hyaluronic acid, and soothing ingredients like niacinamide.”
Anti-Aging Properties

Its ability to preserve skin cells and promote skin hydration contributes to a smoother, more youthful complexion. This is particularly helpful for those looking to combat the early signs of aging and maintain a vibrant, healthy glow.”

Look for Ectoin in moisturizers and serums with a concentration of 0.3%-2.0%. “Ectoin should be incorporated into your skincare routine as a topical serum or cream,” board-certified dermatologist Dr. Ashley Magovern tells Refinery29.
