The Aestura Atobarrier 365 Cream is a K-beauty bestseller, and it's now on sale for Prime Day. Going from $31.99 to $22.39, I'm officially counting this among the best Prime Day beauty deals of 2024. I only see it go on sale about twice a year, so if you're curious about Korean skincare products, this is the time and place to start.

I've been using this face cream for over a year now, ever since my best friend gave it to me. It seems she knows me better than I know myself, because it's the only thing that keeps my extremely dry skin feeling hydrated for over 24 hours.

The Aestura Atobarrier 365 Cream is a heavyweight formula that takes some massaging to evenly distribute. I put it on after I cleanse my face with Tatcha's Rice Wash, and it feels like my skin is absorbing a silky layer of cream. It's practically unscented and while dense, it doesn't feel sticky. I recommend it more so for those with noticeably dry, flaky skin because its intense hydration effect is likely too rich for oily skin.

"Skin barrier" is a buzzy new term in the skincare sphere that I hadn't paid much mind to when shopping for the best moisturizers for acne-prone skin. However, the skin barrier shields you from pollutants while protecting your body's hydration balance, so it's an important aspect to consider for treating dry skin. A key ingredient in the reformulated Aestura Atobarrier 365 Cream is its high-density ceramides, which boosts your skin's ability to retain moisture.

If you're like me and prone to hormonal acne flare-ups, I've found this cream is safe and comfortable to wear even when breaking out. For those with chronic acne, Aestura also has a Theracne moisturizer infused with hyaluronic acid and zinc. I like that the squeeze-bottle makes it portable and helps avoid cross-contamination. I take it with me whenever I travel, and it gives my face the coveted "glass skin" look.

What is "glass skin?"

Glass skin is a well-established trend within K-beauty, though the term was more recently popularized after the viral Pat McGrath makeup artistry from Maison Margiela's Spring 2024 Couture show. McGrath revealed in a live masterclass a wide medley of makeup products used to create the porcelain glaze, but in Korean skincare, glass skin instead refers to a naturally dewy and smooth complexion. This is achieved via a routine that emphasizes hydration, beginning with cleansing, exfoliating, toning, and finally, moisturizing. The Aestura Atobarrier 365 Cream tends to be among the recommended list of products.

The bottom line

Now that this cream has been part of my skincare routine for a year, I'm curious to see if it's recent alleged reformulation with works as well as the original. For Prime Day it's almost $10 cheaper, so I'm choosing to give it a try. In my experience the Aestura Atobarrier 365 Cream works for over 24 hours, so I'm restocking while the getting is good.
