What is this product?

Aestura's Atobarrier 365 Capsule Toner is worth it if your barrier is the problem: ceramide, cholesterol and sphingolipids ride in visible capsules through a PHA water base, and there is no fragrance, dye or essential oil among its 27 ingredients. Do not buy it as a standalone hydrator, though, because the 72 hr hydration headline has no study attached to it and the formula has nothing occlusive in it to hold water in, which is why Aestura's own routine puts a cream after it. Aestura also does not publish a pH for a toner sold on an acid-balance story, and prints two different volumes for it, 150ml internationally and 300ml on its Olive Young listing.

What makes it different?

The capsules are the point: Aestura says they are the same patented high-density ceramide capsules from its cream, so the lipids stay suspended instead of dissolved. Its 33.3 percent immediate hydration figure does rest on a real trial, 30 women aged 20 to 39 over 4 weeks at a named institution, but the same page also reports that result as a 1.3 times rise and never reconciles the two. Two other headline numbers are not checkable at all: 3 times more barrier protection than wipe-off toner names no product, and 1.2 times faster and 28 percent deeper absorption than Amorepacific's toner compares against a corporate sibling the brand never identifies. Its international product page shows no customer rating, so there is no score to go on.

  • 33.3% immediate increase in skin hydration
  • High-density capsules formulated with long chain ceramides and linker ceramides help compensate for the short and insufficient ceramides commonly found in sensitive skin. By forming a denser and more resilient capsule structure, they strengthen the skin barrier while delivering lasting moisture.
