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.


Cocos Nucifera (Coconut) Fruit Extract, Gluconolactone (0.5%), Ethylhexylglycerin, Butylene Glycol, 1,2-Hexanediol, Illicium Verum (Anise) Fruit Extract, Scutellaria Baicalensis Root Extract, Polysorbate 60, Caprylic/Capric Triglyceride, Allantoin, Sodium Hydroxide

After your skincare routine, you can use this as a barrier and boost. Use it on the days you don't wear any makeup and let your skin restore and absorb the moisture. You can even use it on your arms and legs for a glow.


This mist is so gentle, yet moisturizing. It leaves you with that dewy skin we all want. The few ingredients are effective and will keep your skin refreshed throughout the day.


Maintaining a low pH level is very important for our epidermis. Formulated with 98.10% coconut fruit extract and 0.5% PHA (polyhydroxy acid), this mist is designed to keep your skin’s pH at the optimal level, so your skin can better fight off acne-causing bacteria and stay hydrated. You'll notice fewer breakouts as well as smooth supple skin. With a short ingredient list including three fruit extracts, this mist is free of potential irritants like parabens, artificial fragrance, surfactants, and mineral oil. Trust me, it'll be your secret weapon for refreshed and clear skin all year long.


This is a really great mist! Finally one for my girls with combo to oily skin! This wont leave your skin feeling tight or dry just hydrated and refreshed. This will also give you a gentle exfoliation promoting faster cell turnover for smoother looking skin!


It\'s a solid mist and it looks pretty on my desk haha. Though I prefer mists that are bi-phase (oil and water) for true hydration, I appreciate that this one has PHA, a hydrating AHA I\'ve been wanting to add to my routine for a while now. (Sheryll Donerson\'s article on PHA totally convinced me to give it a try.) I like feeling that it\'s rebalancing my skin\'s pH midday. It works great when I use it before my cushion touch-up.


This is on my list to try!
