    Finally a product that fits my greasy skin

    I have tried a few hyluronic serums but with greasy skin and spotty prone skin I found most blocked pores but Inkey seems thinner and sinks into skin easily rather than other sitting on your skin. Less blocked pores and my skin overall looks smooth and healthy, no more flakes. I use Inkey Niacinamide on top and both together have given me great results. It's taken a while to get these results so keep at it.
