About the product

What Is It:

From the K-beauty brand that brought you the K-Beauty Award-winning cult favorite Low pH Good Morning Cleanser comes the latest innovation in low pH skincare: the Low pH PHA Barrier Mist. Formulated with 0.5% gluconolactone, a poly hydroxy acid that is a milder, less irritating, and hydrating version of AHA, this face mist helps your skin maintain its healthy, slightly acidic pH level. (Maintaining your skin’s natural pH level is an important factor in its healthy functioning — read why here.) Spray it on after your skincare routine or even throughout the day to create a moisturizing “barrier” that prevents your prior skincare from evaporating and external assaults out. You’ll want to keep this unscented mist in the pretty blue bottle next to you at all times.

Our insight:

We love spraying this mist on after our skincare routine. It creates a mattified, silky veil that keeps our skin protected all day.

How to use:

Mist on face after your skincare routine and pat in. Can also be sprayed on throughout the day for a pick-me-up.

Cosrx absolutely nailed the spray nozzle on this one. The mist is perfect! My daughter is absolutely addicted to this mist. She would use it all day everyday if I let her. It doesn't make her skin more oily and doesn't leave an unpleasant film. I absolutely love it too. Just a perfect mist of refreshment at any point of the day. It also does not mess with our makeup at all. We also use at the end of our routines just to kinda seal the deal.


I love this mist! First time trying a mist, and I'm addicted to it. I'm definitely going to purchase again this product.


I love this mist! The sprayer is super fine, and I find that using it right before actives after cleansing, I get better performance from my actives. The bottle is also gorgeous, which makes the entire process of using the mist even nicer.


I love this product! For reference, I have very dry and sensitive skin.

The spray is sooo fine and light. I would compare it more to the fine mist of a perfume bottle instead of the larger, wetter mist of a regular toner or setting spray.
This is a bit of a premature review because I have only been using it today, but I have already noticed a difference in my skin's hydration, and there has been none of the normal irritation that comes with testing out a new product.
I live in a very hot climate, so it is great to... Read more
