What It Is

Ectoin is an amino-acid derivative made by extremophile microorganisms as a protective molecule. Cosmetic-grade ectoin is purified for use in hydrating and barrier-support formulas.

It is not an exfoliating acid. Its role is primarily protective and moisture-supportive rather than resurfacing.

What It Does

Ectoin helps bind water and supports the organization of water around proteins and cell membranes. On skin, this can translate to improved comfort, smoother texture, and reduced appearance of dryness.

It is especially useful in formulas designed for dehydrated, environmentally stressed, or easily uncomfortable skin.
