Love this serum! All of my friends and family who see my skin are amazed with the results. I don't know what the secret is, but I have gotten such great color that many people have remarked on it. My skin looks healthy, this by far gives an extremely nature looking tan. I was suffering with eczema and all products that I used before to get tan became my skin red, itchy and very angry. This is the first product for tanning that helps with my eczema.
