Unfortunately many products contain formaldehyde. It is a known human carcinogen. It is also an irritant to the eyes, nose and throat, and can lead to skin irritation and an allergic rash called dermatitis. It is a caustic agent and makes the nail surface harder by burning it. In-fact the nail structure is not improved in essence.

Others act like a lacquer and add a layer to nails. These products don't improve the nail structure. They merely increase the thickness, giving the false strength interpretation.
Moreover, they are hazardous to our nail. Firstly because they damage the nails when they are to be wiped off by conventional nail polish removers.
Secondly they impose a load on nails. The later phenomenon makes serious damages to nails over time. Because the nail is not actually strengthened and the weak nail is just carrying an extra load. It affects nail matrix resulting in the production of even weaker nails.

Hand and nail creams are safer than others, however their efficacy have not been proved.
