As one of the most affordable first essences available, this one performed just as well as many more expensive options! While results did take a while to see, I noticed an improvement in hydration and brightness with continued use. Many claim this is an SK-II dupe, but for me the latter is still more effective and minimizes the appearances of pores. But at the price, Secret Key is a great option!
