The INKEY ListEctoin Hydro-Barrier Serum
Highlights
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.
Directions
Use twice daily, AM & PM. Always use as your first serum after cleansing.
Apply a pea-sized amount to face and neck and follow with preferred treatments and moisturizer to seal the benefits into skin. Always finish with SPF for your AM routine.
INKEY TIP: Apply to damp skin to help lock in hydration

The ultimate shield for your skin🛡️!!!!
I am obsessed with the Ectoin Barrier Serum from The Inkey List. It’s a dual-action formula that repairs and protects at the same time. It feels super silky and keeps my skin hydrated all day long. If you have a damaged barrier, YOU NEED TO TRY THIS. I use it right after I finish cleansing my skin and my skin is a bit damp and then add this serum. You need this in your routine. I also use defferrin 0.1% gel which can be very drying and has sometimes compromised my skin barrier but when I use this serum first it really helps maintain my skin barrier. I also pair this with the omega water cream and it gives glass skin, so shiny and hydrated. 10/10 recommend! ✨

Okay
[This review was collected as part of a promotion.] I haven’t used this much as it makes my other skincare and make up pill. I can only use this at night so not haven’t much of an effect

Great barrier serum
[This review was collected as part of a promotion.] This serum is great for my dehydrated sensitive rosacea prone skin, doesn’t irritate and keeps it calm and hydrated and healthy. Only need to use a small amount too.

Not right for skin prone to oiliness
[This review was collected as part of a promotion.] Goes on well but skin can become a bit of an oil slick by the end of the day.

MY SAVIOUR
Due to use of another product, my skin barrier got absolutely demolished. With constant use of only this product and a rich moisturiser , I was able to reverse that same in a little over a week. Now I now that prevention is definitely better that cute and that this serum will be a staple in my skincare routine!!
