I knew Rhode’s Glazing Milk was hyped, but wondered whether the product truly worked. I was very, very surprised.

Acid-based toners, like AHAs, work wonderfully for many, but they didn't agree with me. In skincare, they're often produced as chemical exfoliants with benefits that include "exfoliation, improved skin texture, and acne reduction," per Medical News Today. Overuse of AHAs can lead to "damage to the skin barrier."

For context, the capsules are a "specialized technology" that embeds onto the skin and allows a "190%" retention rate, according to Aestura. Dr. Koh explained further that the technology "helps keep ceramides in the skin barrier longer and allows longer-lasting hydration." The brand notes that this effect can last up to 18 hours after a single application.

Koh also counts Aestura’s Atobarrier 365 Cream among her favorites, plus CeraVe's Moisturizing Cream ($17), which she recommends to patients — especially those struggling with eczema.
