I am blessed with strong and fast-growing nails. I'm not sure if it's correlated to having strong nails, but my cuticles are a challenge. They'd take over half of the surface of my nail if I let them. I'm exaggerating, but not by much. Wintertime is especially rough on my cuticles, and the skin surrounding my nails becomes tougher.
I love using handmade cuticle balms that are packaged in either small jars or in lip gloss style swivel tubes. There are artisans that make some lovely ones that smell beautiful and work well. The balms, however, can take time to apply and unless I rub the balm in well, it doesn't reach the nooks and crannies between my nails and surrounding skin.
I recently began using a cuticle oil that I prepared myself and store in a repurposed old nail polish bottle. It does wonders in keeping my cuticles and surrounding skin soft and winter-proofed. I haven't yet seen an all-natural cuticle oil, though one might exist... I can make my own, so I haven't actively searched. I have seen brush-on cuticle oils, but they contain synthetics. One mass-market brand also contains alcohol which is drying to the skin.
