Caused new breakouts
I wanted to love this, I really did! I have done research on tranexamic acid and was stoked to find this serum at Ulta for 25 dollars. I have post acne scars and I saw this was highly rated and the price wasn't bad. I used it twice a day as directed and I started noticing new breakouts. I hoped it wasn't his product so I kept using it and I then started to get very tiny red bumps on the areas I applied the serum. I stopped using it. The breakouts went away and I decided I'd give it another try. The same thing happened again. I went into Ulta to return the product. I was told that even with a receipt if it's past 60 days they can't give you a refund or store credit. So be aware of that change in policy and do a patch test with this product first! I feel like there may be some sort of oil in this.

Nope
I used one bottle of this with no issues. I thought it helped some with evening out skin tone. But my second bottle is causing breakouts. More like skin irritation than acne. There is no ingredient in this that shoukd be a problem for me, so I wonder if something has oxidized and I received a bad batch.
