I find that one squirt is more than enough to cover my whole face and neck. My skin has been very oily lately, but I might have been so before I started using this product, so I am not sure. It's not a wonder product - the $100 anti-aging serums probably work better, but overall I HAVE noticed an improvement in my skin. Although I still do have some deeper white heads around my chin and jawline and light black heads on my nose and center of chin, they have definitely become less noticeable than before I started using this. I began noticing the difference after about 2 weeks. I do use a moisturizer as the bottle says 5 minutes after applying the serum. I do this not because it makes my skin feel dry but in an effort to cut down on the oil production.

A clear serum that is dispensed by a temperamental pump, Bliss touts this as getting rid of fine lines and dark spots when used at night before bed.  Bliss advises to use 3 pumps, however, I found that 2 work just as well.  The 1 oz. bottle does seem to last.  The serum is very sticky.  If it has a fragrance, I never noticed it.  Once it was applied, I felt a tightening on my face, which is where that sticky texture comes in.  I did see a "brightening" of the skin within 2 weeks of using it.  I did not notice any difference in lines or dark spots until I was almost through using the bottle, which was well over a month, maybe two.  Then I did notice the lines on my face were practically gone.  The dark spots, however, only appeared to be a tiny bit lighter.  You are to use the serum only at night.  In the morning, I would use a facial scrub, as the product did seem to be exfoliating my skin.  I applied moisturizer in the morning only, not at night, because I was worried the serum wouldn't work as well.  The price is steep so I haven't bought another bottle, but I do miss this serum very much!
