NailTek Citra is a brand new clinically proven nail strengthening system by NailTek that is 100% formaldehyde free.  NailTek's ingenius formula uses naturally occurring aldehydes derived from citrus sources to completely replace formaldehyde, which is normally used in nail strengthening solutions.  These natural elements provide the strengthening characteristics of aldehydes with the health and safety of pure citrus.  When applied daily, Citra helps to develop stronger, more flexible nails in a safer, more natural way!
