Disappointed

This is a pricey brand. I've been trying different brands of spot lighteners to no avail. I thought this was a more trusted brand to "reverse" the appearance of sun spots, but it didn't work for me. I've been using this serum for 6 weeks daily and it does nothing, doesn't lighten them at all, doesn't make any go away. The serum itself looks and smells like white school glue, which I wouldn't mind if it lightened spots. The package says "reduces the appearance of brown spots", but even with applying it daily to my entire face & spot dabbing it directly onto spots with a q-tip I had no change. I know it's a serum, but it shouldn't say it reduces spots if it doesn't. False claims by this product.
