I have been using this for more than 2 months. So far, my skin got horrible breakouts and became more dull than before. 
It is expensive, but it is not working on my face. Now I have big pimples, more blackheads and whiteheads.
Compare to MISSHA time revolution first treatment essence at $49 compared to this at $165!
"there is also limited research, produced by Procter & Gamble (the brand behind SK-II) attesting that the Pitera increases the production of hyaluronan – a component found in the skin’s extracellular matrix – in a synthetic skin model. Since hyaluronan synthesis normally slows with age, this is considered to be a unique way to address the problem of aging.
Does Pitera Work in Other Ways as Well?
Another exciting report from Procter & Gamble is that Pitera (Saccharomycopsis Yeast Ferment Filtrate) reduces production of oxidative species.
Yeast fermentation has been shown to increase the activity of components of the skin known as polygalacturonases. One common polygalacturonase in skin care is allantoin, which is normally soothing for the skin. So perhaps Pitera’s soothing properties stem from increased allantoin production.
Use of the Line
From inspection, my favorite product in the line is the SK-II Facial Treatment Essence ($137.99, Amazon.com) which seems to contain the highest concentration of Saccharomycopsis Yeast Ferment Filtrate (Pitera), as well as sodium hyaluronate."

its expensive, n i got a horrible break out last year 
痘痘肌，大油皮，夏天必須備一瓶~~~而且皮膚會變得細膩透白，not死白。味道也不像大家形容的口水臭，只是沒有香味罷了。雖然價格很不可愛，但是效果確實驚豔啊~~~
