not amazing but a nice product [SEP] i had never used a bamboo serum when i ordered this and was curious about itpredictably i cannot tell that it helped supercharge collagen production or lift sagging skin or reduce the appearance of age spots no serum will do that but i do like the way it helps firm my skin before i apply makeup it has a sticky feel coming out of the bottle mine came with a dropper rather than a pump and it feels a bit odd going on sort of like rubbing mayonnaise into your skin but then it absorbs well and leaves my skin a bit tighter and smoother one reviewer has perfectly described the effect as akin to putting on pantyhose everything just feels held together nicelyi cannot honestly say i will re order this because i use a pore refiner that does a better job of leaving my face makeup ready and vitamin c serum seems to leave my skin clearer and nicer but this works well enough that i finished the bottlefor those who want to use bamboo serum this one is probably worth a try take a look at the wide variance in product pricing
