I have been a loyal customer for years but my last experience was beyond disgusting this is the 2nd time I receive an expired product from them. The first time I just throw out the product second time I ordered Skinceuticals c e ferulic which I have been using for years ( Not through their site) I decide to order it through them the product was delivered in 2 days when I open it it was super dark orange color, anyone knows vitamin C shouldn't be that dark unless if its oxidize or it an expired product there was no expiration date on the package, unfortunately, I went ahead and wanted to give it try since I was out of mine, I used it one time and got a bad rash all over my skin ( I have very clear skin) This pic is after days s of cartizon creams. I tried to contact them there was no email or phone number and when I contact t them through their chat service it was new person every time and ask for the same thing ( sent us pictures of the product/ur skin rection) which I did and been doing for over 2 weeks till I gave up. Will NEVER use them anymore! I will be contacting Skinceuticals to report that!
