As the write-up on the packaging states its best to use with a brand new razor, but this is literally the best shaving cream product I have EVER tried. Not only was there not any bumps or razor burn afterwards, but it left my skin baby soft. Longevity? It has that in spades.. I used it on a Tuesday night and its only now, a WEEK later that I feel like its time to do it again.. The price is a little steep, but you honestly dont need a whole lot, and the results make it worth it, IMO. I bought my first one with the Frosted Cake scent, which smells divine but leaves only a soft lingering sweet vanilla scent - nothing overpowering, very subtle. Ive ordered 2 more in a different scent, 1 for me and 1 for my bff. Try this.. I did and have zero regrets.. Aside from not knowing about this stuff before lol
