Another chemical exfoliant to add to your list!
We all know the hype and craze around AHAs and BHAs but there’s another hydroxy acid that’s making its mark in the skincare realm. Say hello to PHA. I know it might seem unnecessary to add another acid to the already long list and having to wrap your head around another ingredient when you’ve just started to make sense of the difference between AHAs and BHAs. But not fret, it’s not as hard as it seems.
Confused between AHAs and BHAs, here’s everything you need to know!
PHA stands for Poly-hydroxy acid actually falls under the AHA family tree and its benefits are almost exactly identical to AHAs compared to BHAs. The main difference is that PHAs have a larger molecular size making them less potent than AHAs. This means that it is much more suitable for sensitive, compromised skin or anyone whose skin can’t tolerate AHAs/BHAs well as it doesn’t penetrate the skin too deeply and works mainly on the surface layers of the skin.
There are 3 types of PHAs;
- Lactobionic acid

- PHAs are extremely gentle on the skin due to their larger molecular size. This makes them highly tolerable and suitable for very sensitive skin or those with chronic skin conditions like rosacea and eczema.
- PHAs also do not cause the skin to be more sensitive to sun damage like AHAs/BHAs.
Removes dead skin cells
- PHAs benefits the skin just like AHAs, just at a slower rate. They help “deglue” the dead skin from the skin’s surface, contributing to quicker cell renewal and brighter skin.
Evens out the skin
- PHAs can also smooth out the skin’s complexion and texture of any pigmentation and roughness.
Hydrates the skin
- PHAs are humectants meaning they attract moisture from the environment and retains the moisture in the skin.
- PHAs acts as antioxidants that protect the skin from free radicals and environmental stressors, great for anti-aging.
- The antioxidant properties also prevent glycation, a process that weakens collagen and elastin in the skin.
What to note?
- Unlike AHAs and BHAs, there isn’t any drawbacks to PHAs as the chances of experiencing a sensitive/allergic reaction is very slim.
- If comparing the effects of AHAs to PHAs, the benefits of PHAs will appear at a slower rate as they are less potent.
- Do conduct a patch test prior to application.
