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:Â
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:Â 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

A lightweight yet powerful hydrating serum that so
[This review was collected as part of a promotion.] I’ve been using this serum for a few weeks and it’s become a must-have in my routine. The texture is silky and lightweight but still deeply hydrating, it absorbs quickly. My skin feels plump and calm, especially after cleansing or exfoliating. It’s fragrance-free and gentle enough for sensitive skin, which I really appreciate. The packaging looks sleek and the dropper makes it easy to control how much you use. Overall, it gives that healthy “glass skin” glow without irritation or heaviness.

Refreshing and hydrated
[This review was collected as part of a promotion.] This leaves skin feeling soft and refreshed, the packaging is nice too with a luxurious feel with the glass bottle. It has a nice light weight texture which I feel leaves skin bouncy and hydrated.

Beautiful everyday serum 💙
[This review was collected as part of a promotion.] Thank you @Influenster and @aestura_uk for the complimentary Hydro Cera-HA serum in exchange for my honest review. I have used the serum everyday since receiving it and my skin looks plumped and more radiant! It’s so lightweight and absorbs easily without leaving a tacky or sticky feeling.
In my before and after photos you can see how this serum evens out my skintone, gives my skin a radiant glow and during this colder weather didn’t leave my skin feeling dried out. Highly recommend 💙

Good for sensitive dry skin.
[This review was collected as part of a promotion.] Didn’t work for my oily skin, but great for dry skin!
I received the Aestura Hydro Cera HA Serum from Influenster to try out. Unfortunately, it didn’t work well for my skin type. I have oily skin, and this serum made my face feel even greasier and caused some breakouts after a few uses. However, my partner has dry and sensitive skin, and it’s been amazing for him! It keeps his skin hydrated, smooth, and moisturized without causing irritation.
So while it’s not a good match for oily or acne-prone skin like mine, it seems like a great option for those with dry or sensitive skin.

Great for dry and dull skin
[This review was collected as part of a promotion.] Easy to absorb and doesn't have sticky or oily feel. Scent was not strong so it feels fresh. It moisturize skin well and leaves the skin bright and firm.

Really enjoying using this
[This review was collected as part of a promotion.] I’ve been using the Aestura Atobarrier 365 Hydro Cera-HA Serum for a few weeks, and it has quickly become a favorite in my routine. The packaging feels sleek and functional — a sturdy bottle with a precise pump that keeps the formula clean and easy to dispense. It has that minimal, clinical look that reflects Aestura’s dermatological focus, which I really like.
The texture is lightweight and absorbs quickly, leaving my skin feeling soft, hydrated, and refreshed without any stickiness. The star ingredient, the Cera-HA complex, combines ceramides and hyaluronic acid, helping to lock in moisture while reinforcing the skin barrier. I also appreciate the inclusion of niacinamide and panthenol, which calm and smooth the skin over time.
After consistent use, my skin feels noticeably stronger and more balanced — less tight, less dry, and overall healthier. It layers beautifully under moisturizer, making it ideal for both morning and evening use. For very dry skin, I’d still recommend pairing it with a richer cream, but as a daily barrier-support serum, it performs exceptionally well.
Overall: Elegant packaging, thoughtful ingredients, and visible results — the Hydro Cera-HA Serum delivers hydration and barrier repair in a gentle, effective formula

A must have serum
[This review was collected as part of a promotion.] It's lightweight, and I have been loving this formula and the results. The fact that it doesn't have any smell is great for a serum, since it's the first layer of product that is applied to the skin. It's for sure a must-have skin care product.
