consistency is an issue but when it works it is fantastic [SEP] i am always looking for new primers to use with my foundation and concealer especially in the summer when my makeup seems to disappear after walking outside i had not heard of this one and there were not any reviews so i thought i would give it a try pros no fragrance or perfume added to irritate your skin or sheer lightweight formula goes on clear and seems to blur or soften uneven texture of the skin just like the filter on your camera long lastingi put this on at and it kept my makeup in place until i took it off that evening at cons consistency in this formula needs to be adjustedfrom the beginning mine was clumpy and i could actually feels little balls or clumps of something in the first few pumpssome was dried completely and unusable not sure if mine was just an older bottle or maybe the product had been on the shelf too long or it got too hot or cold during shipping wasted a lot of product trying to get the first pumps of what could actually be the pump on my bottle does not work every time maybe a squeezable tube would be better to get a consistent amount of primer does not shrink pores clear skin moisturizethis is definitely just a one purpose primernot necessarily a con or a negative i am just used to using multi purpose consistency of this product is definitely lacking and needs some work or the addition of something to keep it from clumpingoverall this is a decent primer and does what it is supposed to when using under makeup or alone however there are definitely some glitches with the formula and delivery system it needs a little tweaking it is entirely possible i received a bottle that was old or exposed to too high or too low temperatures for too long of a time period and this caused the issues with my bottle of primer if not maybe the addition of another ingredient to keep the primer smooth so it applies evenly and does not clump so easily i will continue to try to use primer and see if it was just the first half or all of the bottle with these issues i will update if anything changesi received this product free in exchange for my honest opinion while testing and then my subsequent review whether positive or negative i hope you have found it helpful thank you
