FAQs

When do I use Ectoin-Hydro Barrier Serum in my routine? Always use this product as your first serum after cleansing. Then follow with your preferred treatments and moisturizer. Always finish with SPF in the AM routine.

Do I use this with Hyaluronic acid, or instead of? Ectoin Hydro-Barrier Serum is perfect for those looking to hydrate and focus on barrier strengthening. As this serum is clinically proven to deeply hydrate up to 10 surface layers deep, you do not need to use Hyaluronic Acid Serum as well. If you want to use both in your routine, you could use Hyaluronic Acid Serum in the morning and Ectoin Hydro-Barrier Serum in your PM routine. However, if you want to use both at the same time, there is no harm - you can never have too much hydration!

Can I layer it with other products? Yes! You can safely use it with all other ingredients both AM and PM. What products should I not layer together?

Is it suitable for sensitive skin?Yes, it is clinically proven to be suitable for all skin types including sensitive skin.

Is it non-comedogenic? Yes. It has been formulated as oil-free

What is the Skin Barrier and why is it so important?The Skin Barrier is a phrase used to describe the outermost layers of our skin that we can see and feel, known as the Stratum Corneum. A healthy skin barrier is described as selectively permeable…Put simply, this means the skin barrier is designed to keep beneficial things in and harmful things out - this is essential for maintaining the skin’s health. Learn more about skin barrier health

What are the benefits of Ectoin Serum providing simultaneous hydration and barrier support?Although they are two different things, hydration and barrier work hand-in-hand and one cannot be healthy without the other. If your skin barrier is damaged, your skin will not be able to retain hydration effectively. And equally, if your skin is dehydrated, your barrier will be compromised. This is why replenishing your hydration whilst simultaneously repairing your barrier is essential for optimizing your skin’s health. Our Ectoin Hydro-Barrier Serum has been uniquely formulated with ingredients that work synergistically to provide deep, multi-level hydration whilst strengthening the skin barrier from the outside-in.

Can I use make-up on top of it? Yes, however we recommend leaving 30-60 seconds between applying each product to allow the skincare to absorb to reduce the risk of pilling.

Does it have SPF? No, this formula does not contain SPF.

How long will it take to see results?Products can take up to six weeks to show full results, due to the time it takes for your skin cells to turnover and the results of any products to reach the surface. Consistency is key, so apply regularly even if you’re not seeing the effects straight away. It can be very tempting to increase use of some products to try and see quicker results, don't overdo it though. More is not necessarily more, and overuse can cause irritation and sensitivity.

Is this product vegan?Yes! This product contains no animal derivatives and is now certified by The Vegan Society.

Is it safe for those pregnant or breast-feeding?Yes! You can safely use it when pregnant or breastfeeding. Read our pregnancy safe skincare guide

Can I use this with prescription medication?We would suggest you consult with your doctor to be sure.

What is the PH level of this product?PH LEVEL: 5.5-6.8

This cream is amazing
Leaves my skin smooth and isn't at all greasy. I use it before the bio-active ceramide and my dry skin is much better now.

Not that impressed - still struggling with dry patches
I’ve used this twice daily as part of my routine for weeks, but unfortunately the dry patches and fine lines on my face have gotten worse!

Excellent addition for my skin.
I confess that I was feeling a little cynical, upon hearing that this product was what my skin was waiting for!
Fast forward a month & from the first day, my skin did enjoy this serum. I didn't think that this serum would do all that the write-ups said that it could.
Well, my skin definitely loves it & I have just received my latest order, for a duo pack of EH- Barrier Serum. Thanks.
