Nail fungus is an infection affecting the nails, most often the toenails. This common condition typically causes discoloration, thickening, and brittleness of the nail plate. Many individuals seek ways to cover these visible changes due to aesthetic concerns.
Why Gel Polish Worsens Nail Fungus
Applying gel polish creates a non-porous, airtight barrier over the nail surface. This sealed environment traps moisture and heat directly against the nail, creating an ideal breeding ground for the fungi responsible for the infection. This occlusive layer significantly promotes their proliferation and spread.
The lack of air exposure beneath the gel polish further accelerates the fungus’s growth and severity. Fungal organisms require specific environmental conditions to flourish, and the anaerobic or low-oxygen state created by the polish can be highly conducive to their development. This continuous moist, dark setting allows the infection to become more entrenched.
The application process, which often involves buffing the nail plate, can create microscopic abrasions. These tiny entry points allow fungi to penetrate deeper into the nail structure, compromising its integrity. Additionally, the UV or LED light used to cure gel polish can potentially damage the nail bed, making it more vulnerable.
Challenges to Effective Treatment
Applying gel polish creates a physical barrier that prevents topical antifungal medications from reaching the fungal infection site. These medications require direct contact with the nail bed to be effective, and the polish prevents active ingredients from penetrating.
Covering the nail also hinders visual assessment of the infection’s progress, making it difficult to monitor whether the fungus is improving or worsening. This lack of visibility can delay necessary adjustments to treatment plans. Masking the infection prolongs its duration and can lead to more deeply embedded cases.
The continuous presence of gel polish means the fungus is consistently in an environment that supports its growth. This constant favorable condition can lead to the infection becoming chronic and more resistant to standard therapies. Keeping the nail covered with gel polish can turn a treatable infection into a prolonged health issue.
Appropriate Solutions for Fungal Nails
Effective management of a fungal nail infection begins with a professional diagnosis from a healthcare provider, such as a dermatologist or podiatrist. Treatment options range from prescription-strength topical antifungal solutions to oral medications, which work systemically to clear the infection. Laser therapy or surgical removal of the affected nail portion may be recommended for persistent infections.
While awaiting full recovery, individuals might consider breathable, medicated nail polishes that allow air circulation and sometimes contain antifungal agents. These are generally considered cosmetic or supportive measures, not curative treatments for established infections. They can provide a temporary aesthetic solution without exacerbating the condition.
Maintaining good nail hygiene is important to prevent recurrence and spread of the infection. This includes keeping nails clean and dry, trimming them straight across, and avoiding sharing nail clippers or files. Regularly changing socks, allowing shoes to air out, and wearing breathable footwear can also help reduce the risk of fungal growth.
