They generally are absorbed into the nail plate only a few layers deep. And when they do, they hold the first few layers together, helping to prevent peeling, and providing some strength, but not really that much. They do not penetrate the entire nail plate. Nail strengtheners/hardeners are not meant for use on healthy nails but rather only people with weak, brittle nails. And they are not for long term use either. Many contain formaldehyde - and over time, this will cause your nails to become weak and brittle due to its drying effect, so use a strengthener only until the problem you are using it for has been resolved, and no longer than that. But, if you already have healthy nails, avoid using it in the first place because it won't do any good, but it could do harm to your nails. If you are having problems with your nails, the best thing to do is to find the cause of the problem, and treat that instead of using things like strengtheners. These act as sort of a band-aid, but they don't provide a cure to whatever problem it is that people are experiencing with their nails.
oh yes, they work. The best thing to do is first use the nail hardener and paint across the nail then up and down across the top of the nail and the back of them if your nails are long enough, then your polish the same way. Works like a charm.
