AESTURAATOBARRIER365 Hydro Cera-Ha Serum - Skin barrier enhancing & hydrating serum
Product Description
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

Perfect
[This review was collected as part of a promotion.] Tried so many different hydration serum in pass few years. In my mind as a good serum first thing first is how long it last on my face and without scent. This serum can do both! My face feel so hydrated and not feel heavy! Also it not scented!

For dry skin
[This review was collected as part of a promotion.] I have sensitive and dry skin, and Aestura Atobarrier365 Hydro Cera-HA Serum is just the right choice. It has a watery texture that absorbs into the skin softly and works great under makeup. The dispenser is great to use. Absolutely great serum for dry skin!

Great hydration boost
[This review was collected as part of a promotion.] I’ve been really impressed with the serum. It absorbs quickly into my skin and leaves it feeling deeply hydrated without any oily or sticky residue. My skin feels soft, smooth, and comfortable all day, and it layers well under my moisturiser and make up. If you’re looking for a lightweight hydration that doesn’t leave your face feeling greasy, I definitely recommend giving this a try.
