So on my last client of the day, I finish her fill, buff her nails, apply gel top coat to one of the hands and it turns out fine. But on the next hand, I do everything like I usually do, but when I put the hand in the light to cure the gel top coat, disaster happens. One finger looks like it has a hole in it (in the top coat) and the others look like the gel has literally shrunk, and they’re bumpy too. I file it all off and start again, but the same thing happens. I try one more time, and it’s still the same. I do it all one more time and even use a different lamp, but get the same results. My bulbs in both lamps are about four months old, so they shouldn’t need replacing yet. What could be causing this shrinking?
