Timeless 20% C E Ferulic Acid serum: I kept this in the fridge so it lasted about six months without oxidizing. The amount inside is just enough for three months but I had been using it on and off. It stings occasionally when my skin is too dry. I definitely notice a brightening difference in my skin texture when I’m more diligent about using this in the morning, but I’m looking for something more gentle so i will not be repurchasing this.
