AESTURAATOBARRIER365 Hydro Cera-Ha Serum - Skin barrier enhancing & hydrating serum
Ceramide + Hyaluronic Acid Face Serum for Sensitive Skin
The ATOBARRIER365 HYDRO CERA-HA SERUM is a lightweight, fast-absorbing serum that delivers intense hydration and reinforces the skin barrier.
What it is:
A dermatologist-tested serum that strengthens the skin barrier and delivers intense hydration. Powered by CERA-HA™, a next-generation hyaluronic acid incorporated with ceramides, it helps lock in moisture and offers 2x longer hydration—supporting long-lasting hydration and a stronger, healthier skin barrier.
Skin Type: Dry & Sensitive Skin
What's in the formula?
CERA-HA, an advanced blend of Hyaluronic Acid and Ceramides, delivers intense hydration and reinforces the skin barrier—offering twice the moisture retention compared to Hyaluronic Acid alone. To enhance long-lasting barrier protection, Ceramide Stabilization Technology is applied. Since ceramides are oil-soluble and typically don't dissolve in water, they are encapsulated in a mesh structure. This allows effective formulation into an ampoule and enables them to remain in the skin's outer layer for up to 18 hours, maintaining a strong barrier and locking in moisture.
The result?
Skin that feels intensively hydrated and comforted, with no stickiness or heaviness. Moisture is delivered quickly to dry, sensitive skin, while the skin barrier is visibly improved—creating a powerful synergy that supports lasting hydration and healthier-looking skin from the first use.
- +281% increase in moisture, delivers 3x more intense hydration in just 5 minutes*
- 100% agree skin feels more hydrated and skin texture appears smoother**
*Based on a 4-week clinical study on 31 women with sensitive skin.
**Based on a self-assessment by 31 women who reported having dry and sensitive skin

Lightweight Serum
[This review was collected as part of a promotion.] I really like the lightweight consistency of this product, it absorbs quickly and provides long lasting hydration. It made a difference to the dry areas of my face as a result of my current prescription. It feels like a clean, minimal product and I while I initially thought it was breaking me out I don’t think this is the case as I paused use for two weeks and my skin didn’t change. It’s a little pricey, but a few drops is enough so I’d consider purchasing it.

Deeply hydrating and strengthens the skins natural
[This review was collected as part of a promotion.] This serum contains 2 of my favourite ingredients: ceramides and hyaluronic acid. These ingredients deeply hydrate the skin and strengthen the skin's natural barrier.
It is gentle, non-irritating, and absorbs quickly, without leaving skin sticky. Overal my skin feels soft, smooth, and plump.

Extremely hydrating
[This review was collected as part of a promotion.] This serum contains ceramides and hyaluronic acid which are meant to improve the skin barrier and give instant hydration. I especially like using it when I can see my skin barrier gets disrupted and my skin starts looking dull and dry. After a couple of days of using this serum, everything goes back to normal.
It's also suitable for sensitive skin and I can confirm it doesn't cause any irritation.
Finally, it works as a really good primer as it leaves the skin tacky and ready for a foundation or concealer.

Hydrating, soothing, premium, gentle, fresh, effec
[This review was collected as part of a promotion.] I was sent the Aestura Atobarrier365 Hydro Cera-HA Serum (30ml) and I’ve found it to be a really solid product overall. The packaging looks and feels premium with a sleek design that gives a great first impression. The texture is slightly greasy for my liking but it absorbs fairly quickly and performs better than many other serums I’ve used before. Once applied, it delivers deep hydration that lasts throughout the day, leaving my skin feeling soft, smooth, and refreshed. I’ve noticed it helps calm any dryness or tightness, especially in colder weather. The smell is lovely too, light and clean without any chemical scent, which makes it pleasant to use each morning. It’s a product that feels like it’s genuinely caring for the skin rather than just sitting on top of it.

Hydrated Glass skin in a bottle
[This review was collected as part of a promotion.] Instantly hydrated my skin!
Such a powerful hydrating serum that doesn’t have a smell or a sticky feeling to it at all. My skin was peeling and cracked this morning before I took the review pictures and the Aestura Atobarrier365 serum instantly hydrating it and made it glow. The bottle seem to last a while. I’m 1/2 through it with using it 2 times a day.
It’s great to keep your skin hydrated if you work in high heat places or go swimming often as well.
All my other skin care products goes over it without peeling and the same with my makeup.
Give my skin that glass skin glow, absolutely love it!
