5 full days of wear
OPI Infinite Shine system in Girl Without Limits
primer, 2 coats of color, gloss topcoat
The pic above is after 5 full days of wear and I'm pretty impressed with how it looks. I could have probably worn it for at least another day or two, but my ADD kicked in and I had to take it off and do a new mani. It was still shiny, and I had what I would consider minimal tip wear.
But..... would I recommend paying the premium price of $12.50 per step for this system? No, I don't think I would. In addition, I didn't feel like the topcoat behaved as well as the quick-dry topcoat I am used to using. I painted my right hand just before bed and went to sleep about 30 minutes later and had some sheet marks the next morning.
Two other home no-light gel systems that I also liked that are more reasonably priced are L'Oreal Extraordinaire Gel-Lacque ($13 for box with base and topcoat bottles together, $8 for color) and the Revlon ColorStay Gel Envy ($8 for each of the three steps). My recommendation would be to skip OPI Infinite Shine and go with either of those.
