Your Questions, Answered
Ectoin is a short-chain amino acid known as an ‘extremolyte’, found in plants and microorganisms that survive extreme temperatures, drought, and UV exposure.
Ectoin in skincare forms a protective hydration barrier around skin cells, helping prevent moisture loss, reduce inflammation, and shield skin from environmental stress.
- Hydration: Ectoin binds water molecules to the skin, locking in moisture for supple, plump, and nourished skin.
- Reduces inflammation: By stabilising the skin barrier and retaining moisture, ectoin helps calm redness, dryness, and irritation, including eczema.
- Plumping: With antioxidant properties, ectoin helps protect against free radicals, supports elasticity, and helps reduce the appearance of fine lines and wrinkles.
- Retinoid tolerance: Ectoin enhances moisturiser efficacy and helps minimise irritation, redness, and dryness caused by exfoliants and retinoids.
The INKEY List Ectoin Hydro-Barrier Serum is ideal for everyday barrier support, with added hyaluronic acid for a hydration boost, while we recommend Dr Sam’s Flawless Moisturiser Intense for repairing a damaged or compromised skin barrier.
