This serum is a good one by any means. I have very sensitive skin that will blush up and get irritated over nothing, but this serum has never irritated my skin the slightest. However, I have not noticed a faster fading of acne pigmentation scars than my skin would normally do on its own.

Another thing to remember is to always know where the extra cap is at, as I believe that is for traveling. Product easily leak and clump out from the squeeze cap, but that does not mean the product will spoil.

All in all; a good serum with little chance of irritating your skin, but with a little clumsy squeeze cap.
