Of this product, first of all I was struck by the Packaging, immediately after its content and what the use of the Products promised: I have already used the Niacimide serum and it is more than satisfactory in the results on the skin; I was a little perplexed by the use of the roller, indeed rollers that I thought were full of various serums depending on the skin's needs, instead I discovered that the external roller has tiny needles which, when passed over the skin, inject the product , but within one or two days, the external roller then becomes smooth and therefore it is necessary to change the roller (there are 3) or to pass a cream or serum that you already own on the face and then pass for 5 or 10 minutes the roller which, even if now smooth, manages to give a good massage on the more complicated areas of the face, such as the jaw, forehead, etc

Unfortunately, this turned out to be a somewhat disappointing product compared to my expectations: only the HYDRO BOUND SERUM is OK. For the other half of the Kit, a half disaster: I DO NOT understand how to make the ROLLERS and the Tools work correctly. I have asked the CULT BEAUTY Customer Office several times for information, notizie and a HELP: they have written to me about 10 times, but they HAVE BEN NOT ABLE TO SOLVE my PROBLEM, also if they SELL directly this Product. I'm really Disappointed. I will only use the Serum Bottle.
