I don't usually use vitamin c even now I've heard it's good for my skin. This doesn't irritate my rosacea prone skin and I've looked at the ingredients and know that this is a quality product.

Literally the third one I ordered and the third time it's come already leaking and oxidized. I ordered the first 2 on Amazon and thought it was just old stock from Amazon. Then I tried buying directly from the Prequel site and it's still the same. Complete garbage and they clearly don't care because it's a well known issue and they just close their eyes and pretend they can't see the complaints.
