The INKEY ListEctoin Hydro-Barrier Serum
Product Description
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

A lovely hydrator!
I ditched HA for this and much prefer it. It works really well with other Inkey products in my routine, and it makes my skin feel soft and bouncy. Love this!

Ok
[This review was collected as part of a promotion.] I'm on my second bottle but I'm not convinced it's doing much to be honest.

Now a Staple of My Regime
[This review was collected as part of a promotion.] The half-face test proved it: absolutely worth the upgrade!This is hands-down the best hydrating serum I’ve ever used. If you're on the fence about spending a bit more compared to a standard pure Hyaluronic Acid, trust me,it is well worth the extra cost. To actually test it, I did a split-face trial for a week: this serum plus moisturiser on one side, and just moisturiser on the other. The difference was night and day. You can absolutely see and feel the results! Highly recommend.

Allergic Reaction
[This review was collected as part of a promotion.] I built my routine on the website and answered that I have sensitive skin. This was the recommended serum so I tried it. After a few days my cheeks were red, blotchy and had breakouts. As soon as I stopped using this and returned to the hyaluronic acid serum my skin calmed down and returned to normal. I have tried it again a couple of times to see if it was perhaps something environmental and I have a basically full serum I won't use but I always have the same result. I'm sad because I heard such good things about this serum. If you have sensitive skin, be careful.
