effective [SEP] i have been watching as every personality is raving about rose quartz and jade and microneedling etc i did some research from reputable sources and there is actually some science to the use of these products the microneedle blade is small enough for use it makes little tiny non noticeable holes in the surface of your skin in effect damaging it so it will produce more collagen while i would not use it more than once a week and just until my skin starts to get red it does appear that my skin is softer and smoother after the treatment so i am find on the micro needler just remember gently gently the quartz roller is supposed to reduce redness smooth the surface of the skin and help with lymphatic drainage i am not sure it actually does all that but it does feel nice and has definitely helped with under eye puffiness so it appears to be working i am very pleasantly surprised by the effectiveness of these devices and will continue to use themthe packaging is fine and makes them giftable but i am not sure the quality of the pieces will actually hold up i have been using them for several months and so far so good but if they do fall apart i am willing to invest in more expensive products for a starter set i would give this a try to be sure it works for you and you are willing to do it
