This serum is my skin savior. I am on my second bottle now. I am 39, with very sensitive skin, some fine lines under my eyes and on my forehead, and some spots. I bought this serum when I realized that my skin turned to worse, I had very small, red spots without head on my face and some weird skin texture like a going to be rosacea. I used 1 bottle of this serum and they dissapeared and my skin became normal. I was not expecting that at all. But it did not happened after the first use, it did happen after i went through the whole bottle. It really helps my skin to be normal. When i use this serum, I do not have spots. Excuse me for my English.
