My first bottle of Retinol 2% seemed ok with a serum texture and look, I bought the second bottle this was so much like watered down, did not look like the first bottle, did not stay on my skin. The worst part was I sent an email to the manufacturer- got me nowhere; went to the retail store where I bought it from- got me nowhere.the box has Batch number but no best before date / expiry date the store manager was looking for - none showing, promises on I will get back to you... never do. No wonder it is so cheap...
