Buffering, Masking

Sodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.

Its main functions are to maintain the pH of a product and neutralize metal ions.

The acidity of our skin is maintained by our glands and skin biome; normal pH level of skin is slightly acidic (~4.75-5.5).

Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.

This is decent but you gotta be careful with it if you’re sensitive. I was dealing with some intense inflammatory acne after messing up my skin barrier. My skin seemed to be on the mend so I tried this thinking my skin wouldn’t still be so sensitive and it would help clear up the remaining congestion left behind by my crazy breakout, but I think I should have waited a little longer or only used it Show more

It’s much gentler than the ordinary’s version while still being effective. Maybe a bit less of a dramatic change but my skin tolerates it much better.

Got this for my spouse to help with eczema, but I ended up using it too to treat a fungal acne break out. I saw improvements very quickly. Very pleased. Not much of a smell, doesn't irritate my skin. Would recommend. They also have higher percents as well.

First time using Azelaic acid and it has helped with redness reduction and my cystic acne flareups. I started using this 2-3x times a week to avoid using too many actives and I feel that 5% is a bit slow to see faster results. I think my skin can tolerate a higher concentration so I will be testing out the 10% version at some other time. The texture of the serum is on the thicker side and does Show more
