Didn’t like AHA? Try PHA

Acid exfoliants have been the rage these days with many different brands coming up with their products that contain AHA and BHA. However, we all know that the K-Beauty king of creating these products is Cosrx, and it’s awesome that they make the products affordable and easily accessible!


Cosrx recently came out with a product that contains PHA—polyhydroxy acid—and it comes in a nice, soft cream form. It’s called the PHA Moisture Renewal Power Cream.

While Cosrx’s AHA and BHA products have proven to be successful on many different K-Beauty skincare enthusiasts, we have gotten reports that they can be a bit too much for sensitive faces.

Good news! PHA is a much milder form but still works to gently exfoliate the dead skin cells of your skin. While PHA possess AHA properties, it is a lot larger in molecular size and is great at providing anti-inflammatory and antioxidant benefits. It is also less penetrating than AHA, which means—rather than targeting the deep layers of your skin, it concentrates more on the surface, helping fine lines to subside and lightening dark spots and hyperpigmentation. Therefore, for people who easily get red or irritated and have a hard time finding the right exfoliating agent, this is definitely worth it to try!

Here is the breakdown of what’s in the cream!

  • coconut fruit extract (50%)
  • gluconolactone (3%) – this is the PHA!
  • niacinamide (2%)

It also features a low pH level of 4.0 ±1, which is a thumbs up in a lot of our beauty books!


Like with every other acids, you MUST be diligent about using sunscreen before you step out into the sun! This will prevent your skin from becoming more sensitive, which will lead to more sunburns, irritations and redness! 

Let us know down below if you’re excited to try PHA and we’ll catch you in the next post!

With lots of love,
