Lippmann is my go-to top coat. Zoya is the only other brand that adds any longevity to manicures on my bendy, chipping fingernails, and this one is the reigning champ. The dry time is great, and it layers on itself really nicely over the course of days to help keep the manicure intact. I would give it a full five stars, but after several months or when the bottle starts to get empty, it becomes thick and eventually turns stringy and unusable. For such an expensive product, that’s a major issue, but it’s so good up until that point that I’ve repurchased several times. Definitely worth a look for weak nails that can’t hold a manicure well, probably less worth the price for those with naturally good fingernails.
