I've actually developed an allergic reaction to gel polish and have had to stop using it and applying it on my friends The skin behind my thumb nails is all cracked, fissured and bleeding. The skin on some fingers, around the cuticle area, is inflamed and sore to the touch.
I knew the risks involved but was at my wits end with peeling and chipping nails that I persevered with gel polish. I read a very interesting article where a Dermatologist was commenting on the whole system. He recommended that you soaked off the polish in acetone until you could gently push it off, rather than scrape it off. Every time you scrape you remove a layer of natural nail. thus exposing it to potential infections etc. He also recommended that you leave it an hour after soaking before reapplying the polish.
As much as I love having perfectly, painted nails, my health is more important so I am having a break from all things nails! Without wishing to sound melodramatic, my thumbs are in agony! You'd be surprised at how much you use them.
