I was using skII essence for the past 2 years, when I first started using it, it really brightens up my skin, even out my skin tone, pores r less visible, skin is more hydrated..etc, but toward the end of last year not only the effect wasn't there, the essence actually made my sky dry, I read somewhere that pitera actually is actually drying on the skin... Hence, I bought this baby.. The essence is pretty good for price paid, but I would say the result is not as visible as skII when o first started using it... Nonetheless, I can tell the difference of not using this for just one day or two if I am travelling... so I am glad I found a substitute for SK ii
