No, it's not that I'm feeling ill (although the thought of going back to work is having that effect). I wore the beige (Revlon Putty) nail polish that I applied on Wednesday night last week until yesterday morning. While I've experienced a slight yellowing of nails from polish before, I really wasn't prepared for the colour that my natural nails had gone. In spite of having used a base coat, they were a brighter yellow than I was expecting in even my worst nightmare. In contrast, the two nails that were covered with gel were still nice and pale except up towards the cuticles where they'd grown out, and the ones overlaid with acrylic but not gel were a bit patchy.
So it looks like I'm stuck with something of a catch 22 situation. I have to wear nail polish to hide the yellow staining of my nails, but by wearing polish, I'll guarantee that they will continue to be stained, unless I have gel overlays done on my nails. Overlays also reinforce the nails, reducing the risk of breakage.
Add in that I'm still having trouble with the side of one nail cracking, in spite of having had an acrylic overlay over a patched edge, and I decided that it was time to head back to the salon to see about getting gel on all my nails. I dropped in yesterday afternoon and made an appointment for this morning, then went home to put some CoverGirl Fuchsia Girl on for last night's cafe night.
