I have used this product only 2 times now, and my sun spots have faded tremendously and the wrinkles around my neck are gone. This is an awesome product. I am going to put a drop or two in my moisturizer at bedtime like another reviewer said she was doing. I would highly recommend this product, each day of the week and twice on Sundays--it is really that good. And, yes, it does sting when you put it on but it is only because it is working.
