I purchased the Vitamin C Ester Treatment and used it for 3 days. My face swelled, my eyes closed and my skin feels like a snake. I obviously have had a very bad reaction to his products. I am on the 4th day of having not used the products but still look as though someone has been boxing on my face. The worst part is that when reading the bottles, there are no ingredients listed on the any of the products. However, the box(if kept, does list the ingredients). When calling Dr Perricone’s 1 – 888 number to let them know about my reaction and to see if they can offer any solution for healing, they are not receptive and offer no solutions. This treatment is suppose to be for wrinkles and since no where does it say NOT to use by the eyes where I have wrinkles, I unfortunately used it there along with the rest of my face. My eyelids are so swollen they fall over my eyes and I have large pockets of swollen skin under my eyes as well as the rest of my face being swollen and extremely dry with no sign of improvement. I have never had a reaction to anything other than cats so this comes unexpected. I realize there are some good reviews about this product on-line but I would be cautious since you don’t know when you will have a reaction and you are dealing with a product line where the company is not receptive in helping you if you do have a problem. I wish you could see my face. it is worth a thousand words,
