Half bottle of SkinCeuticals C E Ferulic. Absolutely nothing wrong with it. I have just switched over to my cooler weather skin care routine. I’m done with it until next summer and I won’t use it after it’s sat all winter open. The picture with the green line shows the fill mark. The last picture shows that I ordered it April 14th from Dermstore. It wasn’t opened right away because I was still using another product when I received it.
