I read about Londontown Illuminating Nail Concealer in a product review and it sounded intriguing. The reviewer and I had the same problem: nails damaged by acrylic application. Why did I believe it when I was sold on the idea that acrylics would strengthen my nails? That may be technically true in some weird way, but *removal* damaged my nails and made them ugly and weak. Enter Londontown Illuminating Nail Concealer. OMGOODNESS! One coat concealed the ugliness, and I’m not sure it’s claimed, but I think the Illuminating Nail Concealer made my nails stronger. For sure it made them pretty in a barely there shade. And there are no stroke lines. I’ve used so-called “sheer” polishes that went on unevenly and left application lines to the point where I had to put on more coats, which defeats the whole purpose of sheer. Londontown Illuminating Nail Concealer isn’t like that at all. One coat with a loaded brush is all it took. Sure, you could put on another coat, but why would you?
