Buyer beware: This product has been reformulated as of 1/27/2012 (or earlier?). After trying many serums, I was so excited to finally find one that really did seem to tighten my skin, give me a youthful glow, and reduce sun spots (brown patches). I have fair, sensitive skin and don't normally wear perfumes and I enjoyed the light fragrance of this product.
However, I don't think I'll be buying it again. Unfortunately, the company has reformulated the product. It no longer includes magnesium ascorbyl phosphate as the form of Vitamin C. It now contains ascorbic acid, and it's almost near the end of the ingredient list, leading me to believe it isn't very potent in Vitamin C.
Also, the smell is no longer nice. Instead of fresh citrus, To me it smells like over ripe or rotting oranges.
It's too bad that a great product had to change. Why? I don't know. The company's customer relations department couldn't tell me. I'm also a fan and user of the renewal facial cream, which she said also has been reformulated.
