As dermatologists, a complete knowledge of various nail products, nail-enhancement procedures, and anticipated complications and their management can result in better patient care.

Allergic contact dermatitis from ethylcyanoacrylate in an office worker with artificial nails led to months of sick leave. Adverse contact reactions to sculptured acrylic nails: 4 case reports and a literature review.

This variety contains cellulose, acetate, butyrate, and polyester resin, [3] with plasticizers such as dibutyl phthalate for softness and pliability, dissolved in solvents (N-butyl acetate or ethyl acetate). Specific colors like red, gold, and silver were chosen for royalty, and the common folk had to use lighter shades. Some manufacturers claim to have "toxic-free nail polish," which is free of toluene, pthalate, and formaldehyde and contains natural pigments in a water base. Adverse events may occur either during the nail-grooming procedure or as a reaction to the individual components of the nail cosmetics. Argan oil, which has a high content of amino acids, has also been used as an important ingredient. Artificial nails date back as far as 600 BC to the Chou dynasty in China, where nails were made from gold, silver, and precious stones. They may contain titanium-silicone-zirconium polymers, polytef, nylon, calcium, and biotin.
Separate "nail-bars" have been set up dedicated to serve women and men interested in nail beautification. They were inspired by the enamel paint used on cars to formulate something similar for the nails. Nail hardeners need to be cleaned off every 2-3 days to prevent onycholysis and chromonychia.
These can be partially attached as nail tips or used to reinforce the entire length as sculpted nails (acrylic or gel based).
These are glued to the free edge of the nails with adhesives containing methacrylate or ethyl 2-cyanoacrylate.


The nail surface is filed roughly prior to gluing the nail tip, in order to improve adhesion. The glued-on tips are then painted or decorated with nail art and finally coated with acrylic or gel [Figure 4]a and b.
Both acrylic or gel-based nails involve a mix of a powder and a solution, applied to the nail. A disposable foil with a printed grid is used as a template for the application of materials.Acrylic nails A few drops of ethyl methacrylate mixed with powdered poly-methacrylate results in a polymerized mixture that needs to be applied quickly due to the instant setting potential.
The powder contains benzyl peroxide, which acts as a catalyst, while hydroquinone acts as an inhibitor of polymerization. A further modification of the process is the gluing of pieces of silk, linen, or fiber glass to the nail, prior to the acrylic application. Acrylic nails can be removed with acetone.Gel nails The powder and the liquid phase of gels is akin to dental resin and requires specific UV-light exposure to set and cure (harden) the gel after application on the nail. These nails appear glossy, are aesthetically appealing, have greater strength for endurance to physical wear and tear, and need less after-care [Figure 5].
Anatomically, the cuticle has a very important role in sealing the potential dead space below the proximal nail fold. A damaged cuticle exposes this walled-off space to external agents like detergents and bacterial, viral, and fungal pathogens. Subsequently, acute-over-chronic paronychia ensues, which, over time, results in nail dystrophy. Dombrowski and Llyod reported a case of chemical damage to the cuticle and nail plate by application of a callus remover instead of a cuticle softener, under occlusion, resulting in arrest of cuticle formation.
Staining was reproduced with D and C red no 7, D and C red no 34, D and C red no 6 and FD and C yellow no 5 lake. Allergic contact dermatitis from nail polishes has been seen to affect distant sites like face and neck commonly, especially on the eyelids and around the mouth. Unusual involvement of other distant sites like the genitals and perianal region have also been reported.
The keratin granulations occurred more commonly when the nail polish was kept on for several months or when it was re-applied without removing the first coat and also when a primer base coat was not applied. The possible role of nail varnish in altering pulse oximeter reading has long been debated. However, it has now conclusively been seen that there is no effect in the measurements from healthy or hypoxic subjects. While waiting for the therapeutic response, cosmetic camouflage helps the patients tide over the mental discomfort. This prosthesis consists of a false nail attached to a silicone finger glove molded to the specifications of the corresponding finger of the opposite hand.
However, the author has seen mothers using it on their children's nails in order to break the nail-biting habit, the deterrent being the taste. Increasing number of technicians are sensitized to acrylate monomers used on sculpted nails. The trend at the parlors is to soak the instruments for 10 min in disinfectants like benzalkonium chloride.
