Keep your hydration levels boosted and your skin’s barrier strong with the Ectoin Hydro-Barrier Serum Duo. This is not just another barrier serum. Combining the power of leading barrier science with advanced hydration, NEW Ectoin Hydro-Barrier Serum is your daily non-negotiable for the ultimate healthy-looking skin. Clinically proven to deeply hydrate and strengthen the skin’s barrier in 15 minutes, get ready for visibly bouncier and smoother skin in just 7 days.

A breakthrough in barrier skincare, the dual-action formula is proven to deliver hydration up to 10 surface layers deep. Hero ingredient Ectoin simultaneously boosts hydration whilst helping to build barrier strength to keep your skin functioning at its best. The addition of multi-molecular Hyaluronic Acid and a 1% barrier blend helps to restore the protective skin barrier from the outside in, enabling it to retain hydration more effectively. With continued daily use, Ectoin Hydro-Barrier Serum helps to visibly improve 5 signs of a compromised skin barrier: dryness, flakiness, dullness, redness, and slackness.  

The milky, lightweight texture effortlessly sinks into the skin leaving an immediate veil of hydration. The fast-absorbing, non-tacky formula layers perfectly under other skincare and makeup. Suitable for use as part of the AM and PM routine.

    Soft and plump skin

    Complimentary from theinkeylist. I was recently gifted The Inkey List Ectoin Hydro barrier serum to try. On first impressions the serum itself is quite lightweight. It has a similar texture to the inkey list hyaluronic acid. I have used it after my retinal, and I follow up with a thick cream moisturiser. I found that it is really good for plumping my skin and making it feel moisturised and leaves me with the nicest glow. I have hardly noticed the barrier benefits yet but with continuous use, I can see how much of a difference it could make to my routine and my skin health in general. It has become a staple in my skincare routine as it makes my skin so soft and supple.
