Skin Care Review: Sudden Change Under Eye Lift Serum

I can't live without this product. When I traded in my eyeglasses for contacts I discovered the dark circles under my eyes. Now I apply Sudden Change after my moisturizer and before my makeup. It's so effective that a 50-year old male friend went out and bought himself a bottle too. I've noticed no ill effects. It does feel a little dry after I apply it but I always use moisturizer and this seems to ameliorate the sense of dryness. I am concerned that I find little info online on this product. It looks like I'll have to clean out my local Wallgreens while they still have it in stock.
