I've been a user of SK-II Facial Treatment Essence and SK-II Aqua Physics Hydrating Gel since circa December 2007/January 2008. I find that it doesn't really improve my skin condition (I have oily/combination/dry skin type with rather noticeable pores), but I do like the moisturiser because it really moisturises my skin and doesn't cause me to break out. Only a little bit is required, and too much will make it oily. However, I am in search of a new moisturiser, since I find that the SK-II Aqua Physics moisturiser would work better with the serum, and it will get rather costly. That's also a reason why I stopped using the SK-II Facial Treatment Essence and switched to Shiseido Eudermine Revitalising Essence instead
