So, the key to having great looking nails and cuticles really is moisture. Yes, even when you have on polish, you need to keep moisturizing. I am really not so good at remembering to keep applying moisturizing products to my nails, but I do apply before bed every night and this seems to be often enough for me. My favorite method of moisturizing my cuticles is to apply a cuticle oil such as CND Solar Oil first. The oil step seems to really be key for me, don't skip out on the oil! After the oil has had a few minutes to sink in I apply a thick cuticle cream to "lock" it into my cuticle. My favorite is Orly Cuticle Therapy Cream, but the Kiehl's cuticle cream works great as well. The point is to have a fairly occlusive cream on over the oil.
On days that I'm making an effort to remember my cuticles, I use hydroxy acid moisturizers on my cuticles. Pictured here are products from CND and Poshe (I have the old packaging of both, I stocked up about a year ago and am still using them up). The idea behind these products is pretty simple: they hydrate and the hydroxy acids help to exfoliate. When I'm using these a few times a day I find that my cuticles look amazing, I don't need to use cuticle remover and I can go ages between hang nails.
