it doesn’t leave bumps or rashes, but it does take a lot longer, I tried it on my legs to make sure it works (it does) but it feel likes day 1 after shaving with a razor. You can see the difference in the pic, but u can also see I still have prickly legs (as my little brother likes to call it) overall good tho, tried on my 🐱 and it’s not itchy or sore.
