i bought this product about 3 weeks ago..but before i got this product on my hand i accidently found this product's review on makeupalley. when the parcel arrives, i was quite scared to put it on my face due to all bad reviews here, but i decided to try it only on my nose and chin area. so far this product did not harm my skin and i felt my skin less oily than usual. i have use it about two weeks and i bet this product was not that scary..i don't know maybe it is too early to said that it worked, but it didn't harm my skin.if it really did, my skin would be harm on the first week..right? anyway, i will not buy it again because it was too expensive to me.
