I can't believe the difference. Have lots of what used to be called beauty marks and dark spots. In just a couple of weeks I saw dark spots fading. Some are almost gone! The serum tightens my skin, evens the skintone and even helps with fine lines. I am thrilled with this. I put it on in the morning after I wash my face. It dries and absorbs quickly. I apply my moisturizer (just coconut oil) and then makeup. I have been using it on my hands but more importantly on my neckline (chest) where I have lots of sun damage. I will keep using this product. With so much improvement in such a short time I am excited to see what it does over time. I just love it and it really works. I did receive this serum for a discounted price in exchange of my feedback.
