I was incredibly sceptical when I purchased my first bottle…it was so small. I had spent a fortune on different products & never found anything that made a difference. Within a week, I could see a huge improvement in my skin quality and tone - with wrinkly, crepey skin becoming youthful again. I have had a lot of saggy skin from weight loss so the areas that have benefited most have been inner thighs, back of arms, hands but I use it all over, once a day. I absolutely would not use anything else...
