This is my favorite item from my last purchase, and I purchase a fair amount of londontown products. The serum is alright, it does make your hands look younger and quite dewy, but the effect is temporary. The restoration cream on the other hand (ha ha...sorry) is permanent in effect and is worth every penny. I will probably buy another one when this runs out because its that good, but the great news is its going to be a looooong time before I need to do that because a very little goes a long way. My nails are normal (not highly damaged in a chemical sense), but I have 4 kids under 8 and no dishwasher (gloves? see note about 4 kids). Use the restoration cream once a day after washing dishes, and it makes the dry flakies from the top level of keratin go away instantly. I also noticed that my nails were harder and felt thicker after two days of using this. In short: buy it if you're looking for perfect nails under your polish. I don't always have time for polish, but I like my nails to be perfect because nothing else in my life is that organized. With this stuff, my house may be in shambles but my nails and cuticles are insta worthy. Win.
